The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation (54% of installed capacity) and hydropower generation (41%). The country still has a large untapped hydroelectric potential. The prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply.
Faced with rising electricity demand (over 6% annually) and declining reserve margins, the government of Argentina is in the process of commissioning large projects, both in the generation and transmission sectors. To keep up with rising demand, it is estimated that about 1,000 MW of new generation capacity are needed each year. An important number of these projects are being financed by the government through trust funds, while independent private initiative is still limited as it has not fully recovered yet from the effects of the Argentine economic crisis.
The electricity sector was unbundled in generation, transmission and distribution by the reforms carried out in the early 1990s. Generation occurs in a competitive and mostly liberalized market in which 75% of the generation capacity is owned by private utilities. In contrast, the transmission and distribution sectors are highly regulated and much less competitive than generation.
Private and state-owned companies carry out generation in a competitive, mostly liberalized electricity market, with 75% of total installed capacity in private hands. The share in public hands corresponds to nuclear generation and to the two bi-national hydropower plants: Yacyretá (Argentina-Paraguay) and Salto Grande (Argentina-Uruguay). The generation sector is highly fragmented with more than ten large companies, all of them providing less than 15% of the system's total capacity. Power generators sell their electricity in the wholesale market operated by the CAMMESA.
CAMMESA S.A., a wholesale electricity market administrator offers operation and dispatch of generation; price calculation in the spot market; and the administration of the commercial transactions in the electricity market. The company also purchases and sells electric power from abroad and to other countries. CAMMESA S.A. offers consulting services. The company was founded in 1992 and is based in Buenos Aires, Argentina.
n 2005, Argentina imported 6.38 TW·h of electricity while it exported 3.49 TW·h. Net energy imports thus were about 3% of consumption.
Argentina also imports electricity from Paraguay, produced by the jointly built Yaciretá Dam. On 18 September 2006 Paraguay agreed to settling its debt of $11,000,000,000 owed to Argentina for the construction of Yaciretá by paying in electricity, at the rate of 8,000 GWh per year for 40 years.
Total electricity coverage in Argentina was as high as 95% in 2003. However, about 30% of the rural population lacks access to electricity.

TECHNO-ECONOMIC EVALUATION OF COAL-FIRED POWER PLANT IN SOUTH EAST NIGERIA, A...IAEME Publication
This research focus on a recent review of the techno economic study of coal fired power plant in south east Nigeria, its application, effects and suggestion in processing the coal and safeguard the atmosphere. Electricity crisis in Nigeria and power reform in the sector is analyzed to determine another source of electricity generation in the country. To recognize the fact that coal is one of the mostly available sources of energy than oil and natural gas. Furthermore, Coal production in different countries and environmental impacts enables us to forge ahead in generating electricity through coal processing. Finally, economic evaluation of the plant will boost coal fired power plant in south east Nigeria.
This application note provides an overview of the most relevant characteristics and considerations regarding commercial and tertiary sector photovoltaic (PV) power plants (100 kW to 2 MW). It is aimed at potential investors, including industrial and tertiary sector companies, communities and financial institutions, among other parties.
Over the past decade, the competitiveness of PV as opposed to other electricity sources has improved considerably, mainly driven by new technological improvements and cost reductions per unit of installed power. In many situations, PV systems represent a profitable and relatively low risk investment opportunity. Nevertheless, a case-by-case analysis should be performed to properly evaluate each project.
The principal technological choices to be made during a PV plant development project concern the actual PV panels, the mounting structures, the inverter, and the storage system. Relatively few major types of systems are currently available on the market for each of these components. This application note describes their main advantages and disadvantages. It also provides a comprehensive overview of the difficulties and risks that can be encountered during the PV plant development process.
The business model of the project will be determined by the local system of government incentives. This application note depicts key issues related to financing and the economics of a PV investment. It describes the choice between a corporate loan and a leasing formula and the calculation of the Internal Rate of Return (IRR). Finally, it executes a sensitivity analysis on the Levelized Cost of Energy (LCOE) of the PV plant. The cost of the EPC contractor and the local irradiation level turn out to be major parameters influencing the result. The discount rate and the lifetime of the PV plants influence the LCOE to a lesser extent. Note that the LCOE needs to be compared with retail electricity prices for residential PV projects, with commercial electricity rates before VAT for company PV projects, and with the cost of other electricity generation sources (e.g. a gas fired combined cycle plant) for electrical utility PV projects.
A Markov model of generator performance at the Kainji hydro-power station in...IJECEIAES
The Kainji hydropower station is a seven turbo-alternator station that for many years served as the base load supply for the Nigerian power grid. Over 200,000 pieces of data about the performance of the machines were used to estimate values of the failure and repair rates for each machine and a Markov steady-state model of the plant was constructed to determine the probability output of the turbines. This result showed that Kaplan turbine (KT) 12 is prone to failure compared to any other KT unit in the hydropower plant. Also, the clusters of probability that define the system state due to the different output capacities of the units show that the hydropower plant has not performed to its maximum capacity, further evaluation shows that 60% of the KT machine units are operating which is consistent with the observed robustness of the output. The model not only conforms to observations but reasonably provide a means of studying the effects of different actions that may be taken to improve the performance of hydropower plant.

An Examination of the Impact of Power Sector Reform on Manufacturing and Serv...IJAAS Team
The main objective of this study is to empirically examine the impact of Power Sector Reform on Manufacturing and Services Sector in Nigeria between 1999-2016. The study employed secondary annual time series data sourced from World Bank database (2016). The methodology adopted for the study was Augmented Dickey-Fuller (ADF); a test for long-run relationship using ARDL Bounds Testing approach with analysis of long-run and shortrun dynamics in the model. A striking revelation from the study is the inverse relationship that exists between manufacturing output and electricity consumption in Nigeria within the period referenced. This negative relationship is not unconnected with widespread allegation of misappropriation of budgeted funds for the Power Sector by successive administrations in Nigeria since 1999. It must be stated in clear terms that constant and consistent electricity generation, transmission and distribution is sine-qua-none for the growth of the national economy. Virtually all sectors of the economy depend on the supply of electricity to do business and so the lack of this vital ingredient of growth contributes in no small measure in stagnating economic growth and development. Efforts at reforming the power sector can only be fruitful when ALL stakeholders in the power sector including the political class put away their personal agendas and take the bull by the horn towards rescuing the nation from the looming danger of stagnant economic growth. Furthermore, there is the need for the Nigerian government to come up with new, better and alternative ways of improving energy generation and supply, as well as proper maintenance of electricity infrastructure in the country.

A research paper that examines the economic forces behind the electricity market in California, specifically on the competition between Investor Owned Utilities (IOUs) and Community Choice Aggregation programs (CCAs). I develop a theoretical model using microeconomic theory to evaluate the nature and effectiveness of an 'exit fee' assessed to CCA customers, known as the Power Charge Indifference Adjustment (PCIA). Background information on the history of the electricity market, the development of the IOU, Community Choice Aggregation, and relevant legislation are also discussed.
Attempting to reduce the existing electricity consumption bill, as well as the stability and non-outage grid recharge with the lowest possible cost and suitable quality, is one of the most important goals for those interested in energy around the world. This paper study the circumstances surrounding the Egyptian society to find the best solutions to a achieved this goals, and it was found that solar energy is one of the best alternatives available for energy. Firstly will be study the electricity consumption bill, slice prices and a program was made to calculate the consumption invoice moreover another program for quick estimation to the proposed solar system.The proposed system provides a smart integration between the solar system and grid, where the supply sustainability and the optimal cost are considered. This configuration allows the two sources separately or simultaneously supply the loads depending on photovoltaic extracted energy. Operational analysis of the proposed system will discussed in this paper. The proposed system consists of solar cells, charge controller, batteries and inverter plugged to automatic transfer switches (ATS) using Programmable Logic Control (PLC). The system grantee a safe and reliable load feeding independently on the grid status. The system durability is the most depicted feature through the modelling and experimentally results. A typical case studies for about four years of non-outages photovoltaic-grid hybrid supply (the implemented system) will be presented and discussed.
DESIGN AND CONSTRUCTION OF A 0.5 KW SOLAR TREE FOR POWERING FARM SETTLEMENTSIAEME Publication
Nigeria is a country faced with great challenges in the power sector. This is as a
result of inadequate administrative and technical efforts in handling issues in this
sector. Aforetime, the country has solely depended on grid electricity generation
which has proven to be unstable for several decades. These and others, has made it
imperative to introduce the use of renewable energy in addressing some of the
electricity challenges facing the country. The sources of renewable energy which
could serve as an alternative source of power include wind, solar, and biogas. These
can also be combined together as an entity to form a hybrid renewable energy source.
In this paper, a solar tree was designed and constructed to provide an alternative
supply of electricity to farm settlements in Nigeria. This is achieved by generating
electricity from a single or multiple number of solar panels connected with a charge
controller, a battery bank for storage and an inverter circuit to supply electrical
power. Depending on the electrical load demand and the applications coverage area,
the solar tree rating and specification can be a single-phase or three-phase AC output

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

I. Introduction
The Philippine Electric Industry has developed and evolved from being a state monopoly
to a deregulated and private industry. But this transformation however, did not come without
much controversy, criticism, and concern. From the imposition of EO 215 (Executive Order 215)
in 1988 to the Electric Power Crisis Act in 1993, the BOT (Build-Operate-Transfer) Law in 1994,
and then the EPIRA (Electric Power Industry Reform Act) of 2001, the benefits of private firm-
produced electric power has not yet been felt by the people. The efficiency promised by the
EPIRA has not yet been realized. This research paper aims to investigate the accrued effects of
the electric power industry reforms since 1988 to the Philippine economy.
As of February 7, 2011, the Philippines has surpassed Japan in having the most
expensive electricity rates in Asia1.This should come as no surprise since the electricity rates in
the Philippines has long been regarded as one of the highest in Asia. How this came about is
arguably not that much unexpected. This paper shall discuss the various reasons why our
electricity rates are very high and why this should be a cause for economic concern.

The discussion will start from the origins of the Philippine IPPs (Independent Power
Producers) leading to the rationale behind the PPA (Purchased Power Adjustment), then
followed by the various reforms under the EPIRA. The paper then details the economic effects
of the implementation of the EPIRA and the Wholesale Electricity Spot Market (WESM), the
present state of competition of the Philippine Electric Industry and how it is affecting the high
electricity rates that the Philippines have been facing. Finally, the reasons why electricity rates
are high will be presented as well as some recommendations on how to mitigate its
macroeconomic effects.

II. Thesis Statement
The existence of the IPPs and the PPA has been justified by the state of the economy
and budget deficit position of the government during the early 1990s but the over-commitment
to the IPPs contributed significantly to the high electricity prices during the late 1990s.
Together with the IPPs and PPA, the Philippine Electric Industry’s transition from
monopoly to oligopoly is the primary cause why our electricity prices today are the highest in
Asia, notwithstanding other factors such as taxes, the transmission system, and dependence on
imported fuel.
III. Body
Independent Power Producers – History and Rationale(Woodhouse, 2005)
EO 215
During the first Aquino administration, it has been forecasted that there will be an
electric power shortage. This prompted the government to pass EO 215. This order effectively
ended NPC’s (National Power Corporation) monopoly in the country by allowing private
companies to build power plants and supply power to NPC and the local distribution utilities.

The effects of the deficiency on added power plant capacity brought by EO 215
culminated during the Ramos administration. In 1992, the lack of added capacity resulted to
rolling blackouts. Because of this, in 1993, Congress passed the Electric Power Crisis Act that
authorized the executive branch to contract IPPs on a fast track basis. Since it was on a fast
track basis, most of the IPPs that were contracted have generating capacities that were based
on combustion turbines and diesel engine technologies. It is important to note that these
power plants have short construction times compared to other technologies like coal thermal
and hydroelectric and that these power plants have low capital costs and can be operational
within a year. These power plants however, have high operating costs.

Although these power plants became quickly available to address the electric power
shortage, these plants were dispatched as base load units (ran 24 hours a day) rather than their
typical use as peak units (only during peak hours) making the overall dispatching of power
plants very expensive. Based on the economic dispatching of generating units, diesel and
combustion turbines (different from combined cycle technologies) should be dispatched only
during peak hours because of their high heat rates (BTU per kWh, a measure of efficiency) and
high operating costs2.
Figure 3 shows the typical demand curve that is unbundled according to base,
intermediate, and peak. Each classification of demand ideally uses particular set generating
units that would result to a lower overall cost. Baseload power plants typically include nuclear,
geothermal and coal. Intermediate power plants are combined cycle gas turbines that run on
natural gas. Peaking plants include combustion turbines, diesel, and sometimes hydroelectric.
This is the economic dispatching of power plants.

When the power crisis ceased, high economic and demand growth was projected so IPP
contracting continued. These power plant projects include large baseload plants like Sual (1200
MW), Pagbilao (700 MW), and hydroelectric and natural gas plants such as Ilijan became online
in the late 1990s.
Nature of the IPP Contracts
IPPs that are operational during 1988-2001 sell their output energy either to the
government (through NPC, PNOC, or NIA) or to distribution utilities such as MERALCO. Their
operations are covered by contracts that can take the form of either a Power Purchase
Agreement or an Energy Conversion Agreement in which the government purchases fuel and
pays the IPP for the electrical conversion of that fuel.
The nature of these contracts is such that all risks except the construction and operation
of the power plants are shouldered by the government. Given the power situation at that time,
the government was of no position of strength and therefore had to make the contracts
attractive to the investors. The common elements of the risks that are assumed by the
government include:
Market Risk
o This refers to the MEOT (minimum energy off-take typically in the range of 70-
85% of power plant capacity factor) in which NPC can pass to the consumers, the
costs attributed to the take-or-pay provisions. This means that consumers would
have to pay for power that they did not actually consume
Ateneo Graduate School of Business 7
9. [THE ECONOMICS OF ELECTRIC ENERGY: IPPS, THE PPA, AND THE
November 7, 2011 ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)]
Fuel Risk
o The ECAs have this provision in which the price and availability risk are passed on
to consumers
Foreign Exchange Risk
o Most IPP contracts have dollar-denominated components on fees and the risk of
the Peso-Dollar exchange rate is also passed-through
Other Payments
o Pass-through payments involving cost recovery and operations and maintenance
Sovereign Guarantee
o Most IPP contracts are backed by a sovereign guarantee
Effects of the IPP Contracts(Woodhouse, 2005)
Asian Financial Crisis
The Asian Financial crises proved to be a blow for the Philippine government and
electricity consumers because the IPPs were contracted based on a very high GDP growth
forecast by NPC. GDP growth is a good indicator for electricity demand growth. According to
the Power Sector Study of the World Bank, during that time, NPC based its projections on a high
forecast of 12% while the World Bank used a more conservative approach and used the 9.5%
figure. Figure 4 shows Philippine’s historical GDP and it shows the steep drop in output during
the Asian Financial Crisis. Actual demand against projected demand is seen on Figure 5 and it
also includes the annual levels of installed and dependable capacity of generation.

Because of the fall in GDP, electricity demand fell and there was a huge oversupply in
generation capacity. This resulted to higher per KWh electricity ratesthat NPC is paying because
of the take-or-pay provision of the contracts. And since this is a pass-through provision,
consumers were burdened for paying electricity that was not consumed.
Devaluation of the Peso
The devaluation of the Peso worsened the electricity price situation because of the
foreign exchange risk provision in the IPP contracts. In addition, since the Philippines has no
extensive domestic reserves of fuel, NPC had to import most of its fuel needs.
Figure 6 illustrates the historical foreign exchange rate of the Peso relative to the Dollar.
The Asian Crisis resulted to a huge devaluation of the Peso. As long as we have IPP contracts
that have dollar-denominated payments and imported fuel, electricity prices will remain at risk
of the foreign exchange rate.

Purchased Power Adjustment (PPA)(Department of Energy)
The PPA is the automatic cost recovery system to cover for the adjustments in cost not
included by the basic rate of NPC. To state it in another way, the PPA is the mechanism that
NPC uses to pass to the consumers all the various risks borne by the government in all of its IPP
contracts. These include the risks in minimum energy, fuel procurement, and foreign exchange.
The PPA is charged by the distribution utilities or electric cooperatives like MERALCO
and BENECO and just mirrors what NPC is charging these utilities and cooperatives. What NPC is
charging are all the adjustments based on the risks and indexation provisions in NPC’s
generation costs and IPP contracts.
NPC’s cost recovery adjustments are generally divided into two parts: the FPCA (Fuel
and Purchased Power Cost Adjustment) that covers the minimum off-take and fuel risks, and
the FOREX (foreign exchange) which covers the foreign exchange risk. Figure 7 illustrates NPC’s
charges. Figure 8 on the other hand, shows what NPC adjustments look like for the customers
of MERALCO.

The Burden of PPA
Because of the multitude of risks that are passed on to the consumers, the effects have
been so far condemning. The Asian Crisis taught us how expensive NPC’s generation rate can
be. Recall that during the Asian Crisis, the Philippines experienced a slowdown in demand
which meant a higher rate because of the minimum off-take IPP provision. In addition, the
devaluation of the Peso also contributed to the rate increase because of the FOREX component
of the PPA. Figure 9 shows how the PPA grew over time.

EPIRA (RA 9136)(Philippine Electricity Market Corporation, 2005)
Despite the PPA, NPC did not succeed in passing on to the consumers all its costs. Aside
from the fact that in 2000, NPC had around $6.6 Billion in outstanding loan facilities of which
50% is US dollar denominated and 45% is Yen denominated3, regulation prevented NPC from
passing on to consumers all of its PPA adjustments.
With the ballooning deficit of the government and the intent to privatize the huge
capital expenditures and risks of the electric power industry, the government pushed for a
reform in the electric power industry. This came into fruition in 2001 when Congress passed the
EPIRA or the Electricity Power Industry Reform Act.
The EPIRA has the following objectives:
Ensure the quality, reliability, and affordability of the supply of electricity
Ensure transparent and reasonable prices of electricity in a free and competitive
market
Enhance the inflow of private capital and broaden the ownership in the power
generation, transmission, distribution and supply sector
To assure socially and environmentally compatible energy sources and
infrastructure
To promote the utilization of indigenous, new and renewable energy resources
in power generation in order to reduce dependence on imported energy

Provide an orderly and transparent privatization of NPC assets and liabilities
To accomplish all these objectives, the electric power industry needs to be
restructured.The restructuring mainly involves the separation of the competitive and the
monopolistic components of the industry. The competitive components of the industry are the
generation and retail sectors while the monopolistic components are the transmission and
distribution systems. EPIRA also involves the unbundling of electricity tariffs to ensure
transparency.
Before restructuring, there are basically just three sectors in the industry. These are the
generation, transmission, and distribution sectors. Figure 10 illustrates the electric power
industry before EPIRA while Figure 11 shows the new structure. The retail function has been
handled by the distribution sector. It will be opened up to Retail Electricity Suppliers (RES) once
“Open Access” has been put into commercial operations.

Figure 11: The New Electric Power Industry Structure
Philippine Electricity Market Corporation. (2005). WESM Commercial Operations Training Module 1.
For the new industry structure, the EPIRA declares the generation of electric power
competitive and open and shall not be subject to regulation by the ERC (Energy Regulatory
Commission). The transmission and distribution sectors will still be subject to the ratemaking
powers of the ERC. The supplier sector, or the retail sector, is also not regulated although
entities under this category will be required an ERC license.
Along with the industry restructuring, the EPIRA created the National Transmission
Corporation (TRANSCO) which shall assume the electrical transmission function of NPC.
TRANSCO is the lone entity in the transmission sector.
Another entity, the Power Sector Assets and Liabilities Management (PSALM)
Corporation, is also created by the EPIRA to administer the privatization of all disposable assets
of NPC (including TRANSCO) except SPUG (Small Power Utilities Group). PSALM is also
responsible for liquidating all financial obligations and stranded contract costs of NPC.
16 Ateneo Graduate School of Business
18. [THE ECONOMICS OF ELECTRIC ENERGY: IPPS, THE PPA, AND THE
ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)] November 7, 2011
The EPIRA has provisions on cross-ownership between sectors of the industry, market
power abuse, and competitive behavior. According to this law, no generation company or
distribution company shall be affiliated with the transmission sector entity TRANSCOor its
concessionaire (now National Grid Corporation of the Philippines or NGCP).
Aside from breaking the state monopoly, the EPIRA was envisioned to transform the
industry into a more competitive marketplace. Aside from deregulating generation and supply,
the law also established the Wholesale Electricity Spot Market or WESM to achieve this aim.
WESM
The Wholesale Electricity Spot Market was established to provide the mechanism for
reflecting the true cost of electricity outside of bilateral contracts. The aim of the WESM is to
establish a competitive, efficient, transparent, and reliable market where:
A level playing field exists among WESM Participants
Trading of electricity is facilitated among WESM Participants within the Spot Market
Third parties are granted access to the power system
Prices are governed as far as practicable by commercial and market forces
Efficiency is encouraged
Ateneo Graduate School of Business 17
19. [THE ECONOMICS OF ELECTRIC ENERGY: IPPS, THE PPA, AND THE
November 7, 2011 ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)]
The basic features of the WESM are:
Gross Pool
o All energy transactions are scheduled through the market
Net Settlement
o Bilateral Contract quantities transacted in the pool can be settled outside of the
market
Locational Marginal Price
o Marginal price computed at each node or location to reflect transmission loss
and/or congestion
Reserve Co-Optimization
o Reserve and energy offers are scheduled at the same time
Demand bids
o Customer’s choice to buy energy lower than a specified price
Mandatory Market
o EPIRA mandates procurement of at least 10% from the market for distribution
utilities and electric cooperatives

How the WESM Works
The WESM basically allows the price and electricity volume to be determined through
the interaction of supply and demand “on the spot”. Since electricity cannot be stored,
transactions should be done in real time. A basic illustration is showed in Figure 12, where the
market-clearing price (MCP) and the market-clearing volume (MCV) are determined by market
forces.
Figure 12: Basic Illustration of MCP and MCV
Philippine Electricity Market Corporation.(2005). WESM Commercial Operations Training Module 1.
The market bids (demand) and offers (supply) are actually arranged in MW (megawatt)
energy blocks. The supply and demand curves look like step ladders as shown in Figure 13. The
WESM also determines the actual merit order of dispatch of the generators. The generators
that offer the least will get to be dispatched by the system first. The market clearing price is the
price that would be paid by all customers and paid to all generators. The cheapest plants will
have the incentive of having a bigger producer surplus.
Ateneo Graduate School of Business 19

November 7, 2011 ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)]
Figure 13: WESM Demand/Supply Curves and Dispatch Scheduling
Philippine Electricity Market Corporation.(2005). WESM Commercial Operations Training Module 1.
The current market, however, does not include demand bids yet. The unavailabilty of
customers’ historical metered demand makes it difficult for them to make meaningful bids, that
is why until now, demand bids are not yet in effect4.
But note that electricity demand is like demand for oil. It is highly inelastic. Meaning, at
any given point in time, we can assume that demand is a vertical line and the intersection of the
supply energy blocks and demand determines the market clearing price. The market clearing
volume will always be equal to demand.
An example is shown in Figure 14. Suppose that the demand for a given trading interval
is 400 MW. Generator A offers 100 MW at a price of 1000 Php/MWh. Generator B offers 250
MW at 1500 Php/MWh and Generator C offers 500 MW at 2000 Php/MWh. The generators will
be dispatched according to merit order (cheapest plants will be dispatched first) until supply
meets demand. In this case, only 50 MW will be taken from Generator C and Generator C is the

The WESM is fairly simple and theory suggests that if an electricity market is
competitive, the spot market will encourage efficiency and lower prices. But will this system
work if the industry has a high market concentration? We now turn to this and examine the
current industry concentration.
Ateneo Graduate School of Business 21

Market Concentration and Oligopoly
Almost every time that MERALCO raises its generation charge, very seldom do you not
hear that WESM played a vital role. Last June 7, 2011, Meralco again raised its generation
charge with WESM as one of the reasons for the increase.5
The WESM provides an avenue for buyers and sellers of electricity to trade electricity
like a commodity. In a perfectlycompetitive setting, the WESM like any other commodity
market, should demonstrate efficiency in which electricity is allocated at the least possible cost.
However, like in many cases, the WESM is imperfect.
The generation sector, according to the Market Assessment Group of the Philippine
Electricty Market Corporation (PEMC), has an industry concentration that is between the
moderate and high levels depending on the measurement used (based on registered capacity,
offered capacity, actual generation, etc.).
Market concentration is measured using the Herfindahl-Hirschman Index or HHI. HHI is
the standard measure of industrial concentration used by the United States since 1982 6 and is
adapted by the Market Assessment Group of PEMC as one of the ways to measure competition
and assess the spot market condition. The HHI is calculated by expressing the market share of
each firm in the industry as a percentage, squaring these figures, and summing. 7

ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)] November 7, 2011
In the WESM, an HHI of below 1000 indicates no concentration. An HHI of between
1000 and 1800 is moderately concentrated. An HHI that is between 1800 and 2500 indicates a
concentrated market while an HHI that is above 2500 is highly concentrated.
The generation sector is currently dominated by four firms: First Gen Corporation of the
Lopez group, Aboitiz group, and San Miguel Corporation, and PSALM Corporation. Figure 15
shows the market share of the generation sector suppliers of the Philippines. Figure
16illustrates the major suppliers’ historical market share by registered capacity while Tables 3-4

Meeting: Market Assessment. Quezon City
From 2009 to 2010, the market share of PSALM has gradually decreased. This is
reflective of the decrease of the monoplostic market share of NPC. The decrease of NPC’s, or
PSALM’s in this case, market share is the result of the sale of NPC’s generation assets. The
24 Ateneo Graduate School of Business
26. [THE ECONOMICS OF ELECTRIC ENERGY: IPPS, THE PPA, AND THE
ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)] November 7, 2011
assets have been acquired by various industry players including new entrants such as San
Miguel Corporation.
As PSALM’s dominance decreased, a new market power emerged. Excluding PSALM, the
largest suppliers are First Gen Corporation, the Aboitiz group, and San Miguel Corporation. The
once monopolistic structure of the industry has produced a new kind of imperfect market
structure: Oligopoly.
Oligopoly is a form of industry structure characterized by a few dominant firms. Market
concentration tends to lead to pricing that is above marginal cost at equilibrium and output is
below the efficient level8. Just how concentrated is the generation sector? Figure 17 shows the
HHI by Luzon major participants from June 26, 2009 until December 25, 2010. The year 2009
shows the dominance that PSALM is enjoying during that time and as generation assets were
sold, the market share of other participants grew and it resulted to a decrease in industry
concentration.
However, if the measurement is based on registered capacity that is net of outage,
offered capacity in the market, actual generation and spot market transaction, the HHI level will
reach the concentrated to highly concentrated level. Figure 18 shows the HHI of the Luzon grid
from June 26, 2009 to December 25, 2010.

Residual Supply Index
The residual supply index (RSI) provides a measure of the degree of pivotal supplier
power based on fundamental economic intuition9. The pivotal suppliers are the suppliers who
can raise the market price substantially by withholding generation capacity10. The RSI measures
the collective capacity of all generators as a percentage of total demand but excluding the
largest generator or supplier. A measure of below 100% indicates that the largest supplier is
pivotal. The lower the value, the higher is the pivotal power of the pivotal supplier.
Figure 19 shows the RSI of the market between June 26 to December 25, 2010. In this
period, pivotal power is above 60%.

Pivotal Supplier and Price Setting Frequency
Besides the market abuse case against PSALM that was filed by PEMC’s board of
trustees (a 73% increase in prices but ERC junked the case on June 6, 2007 because of lack of
evidence), there has been no filed complaints against market abuse. Because of the high
concentration and RSI of the market however, it is very possible that some market power is
being exercised by the firms who hold the largest market shares.
There are two measures of market power. One is the Pivotal Supply Index in which a
particular supplier (the pivotal supplier as discussed earlier) has an integral role in supplying the
demand for electricity at any time. If the pivotal supplier chooses not to generate, then there
may be adverse effect in market that would raise the clearing price. In fact, market power due
to the presence of pivotal suppliers has been documented to contribute to high prices and
inefficiency in wholesale electricity markets and is a significant concern for public policy toward
the electric industry11
The next measure is the Price Setting Index. It measures the frequency of market-
clearing price setting of a particular supplier. If a supplier is both a pivotal supplier and price
setter above marginal cost, then you have an exercise of market power.
Table 4 shows the Pivotal Supply Index of the power plants from July to December
2010. This research will only concentrate on Luzon for simplicity. The values are the percent of
the time each month that a power plant is considered a pivotal supplier. Table 5 shows the

average percent of the time that the power plants of the three major generator groups namely,
San Miguel, Aboitiz and First Gen have been considered as pivotal suppliers.

Taking the average of all the power plants of the three major participants, we can see
how their sizes influence the dependence of the Luzon grid to their power plants. In Table 5, of
all three major participants, San Miguel has the highest average percentage of being a pivotal
supplier.
Table 6 shows the Price Setting Frequency Index of the Luzon power plants from July to
December of 2010. The values here only shows the instances where the market clearing price is
above Php 5 per KWh or Php 5000 per MWh. Table 7 on the other hand, reflects the average
percentage of the time that the power plants of the three major participants have set the price
in the spot market.

Table 7 shows that at the price range of above Php 5000 per MWh, only San Miguel and
Aboitizhave set the price in the market.
With the market hovering between the concentration levels of moderate to high and
the residual supply index falling below the level of 100% at least 60% of the time between July
to December 2010, it is quite possible that some market power has been exercised. The price
setting frequency of the three largest pivotal suppliers sets a warning for Market Surveillance
Committee to continue their monitoring for market power abuse.
The data presented however, is not enough evidence that market power has indeed
been exercised. But the values clearly show that the present industry structure where you have
a moderate to high industry concentration is very prone to market power abuse and there is a
high probability that it can be exercised. That is if it has not been exercised yet.
So far, there has been no word yet if the Market Surveillance Committee of PEMC has
proven market power abuse of the three largest suppliers. But this intensifies the call for them

IV. Conclusion
Why Philippine Electricity Rates are high(Woodhouse, 2005)(Freedom from Debt Coalition,
2009)
The IPP structure that resulted to the PPA, and the oligopolistic structure of the
generation sector are the top reasons why electricity rates in the Philippines are now the
highest in Asia.
The following is a list of why the electricity rates in the Philippines are high.
1. The Oligopolistic Structure of the Generation Sector
The market concentration of the generation sector clearly indicates that the sector is
oligopolistic in structure. Although the evidence is not complete in proving that the largest
suppliers are exercising market power, economic theory suggests that in any oligopoly, there is
a tendency that the resulting price is higher than that of the perfectly competitive market and
output is below the efficient level. This structure is also prone to tacit/explicit collusion
between participants
2. Structure and Implementation of the IPP program
Because of the risks that were eventually passed on to the consumers, the PPA became
very expensive and has now been comparable to the base rate charge. The rapid build-out of
the peaking power plants, the minimum off-take requirements, and foreign exchange risk has
increased the cost of electricity substantially.

3. No Extensive Domestic Reserves of Fuel
With the exception of our natural gas requirements which is supplied domestically
through the MalampayaDeepwater Gas-to-Power Project (which is operating at near capacity),
our requirements for coal and oil have to be sourced from foreign countries. Transportation
costs plus the foreign exchange rate can significantly increase the cost of fuel needed to
produce electricity.
4. Transmission Infrastructure
The transmission system investment is relatively higher in the Philippines compared to
other countries primarily because of the challenge of transmitting electricity over hundreds of
dispersed islands. Inter-island connections are typically connected through submarine high-
voltage DC systems. The cost is made worse because of the need to build transmission lines
that can withstand earthquakes and tropical storms.
5. Lack of Local Capital Markets
The lack of local capital markets has resulted to firms and even the government itself, to
borrow abroad for most of its finance.
6. The Country’s Electricity Demand Curve is “Peaky” Compared to other Countries
The lack of a strong industrial electricity base demand on a 24-hour basis does not help
in reducing the cost of installing generating facilities to cover the peak demand.

ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)] November 7, 2011
7. No Domestic Source of Equipment
As with coal and oil, almost all major equipment used to produce and transmit electric
power must be sourced abroad and is exposed to foreign exchange risk.
8. EPIRA allowed the existence of Distribution Utilities sourcing its electricity requirements from
its sister IPPs
Critics argue that the EPIRA “had” to be crafted to accommodate some of the existing
industry structure before 2001. One of which is the cross ownership of generation and
distribution companies. We have MERALCO and First Gen in Luzon and VECO and Aboitiz Power
in the Visayas. According to the Freedom from Debt Coalition (FDC), MERALCO pays its IPPs
more than what it would have paid NPC if it bought the electricity from NPC. Another
controversial topic of this structure is the existence of a similar “take or pay” provision of
MERALCO’s contract with First Gen, which the Lopez family both have shares with.
9. Value-Added Tax (VAT)
VAT now includes oil and electricity. The consumption tax regime before exempted oil
and electricity because of its “socially-sensitive” nature, meaning raising its prices will raise the
price of other commodities.
Another controversial application of VAT is on system loss. System loss is electricity
which had been generated but not used such as line losses (natural losses of electricity in lines
that are converted to heat), pilferage, and station use.

10. Royalty Taxes on Indigenous Fuel Sources
According to the July 3, 2009 press release of the Senate of the Philippines by Senator
Juan Ponce Enrile, royalty taxes have amounted to 1.79 Php/KWh. This is eight times higher
than the importation tax of oil and coal which is not higher than 0.22 Php/KWh.
There have been calls by various stakeholders to scrap or at least reduce the royalty tax
on natural gas. According to Dr. Francisco Viray, President and CEO of Trans-Asia Oil and Energy
Development Corporation and former Energy Secretary, proceeds from the royalty tax can be
used to subsidize the electricity costs of the industries that are vital to the macro-economy,
such as export industries so they can be competitive.
V. Recommendation
To lower electricity rates, the following should be considered:
1. Increase GDP to increase electricity demand
To counter the effects of the generation sector’s oligopoly structure, the government
should introduce other incentives to spur growth in GDP that would increase the demand of
electricity. Although it may seem at first that increasing GDP to lower the electricity rates is a
“chicken and egg” situation, the government can use proceeds from the VAT and royalty taxes
to create incentives for firms to increase their output. The incentives can be in the form of

38. [THE ECONOMICS OF ELECTRIC ENERGY: IPPS, THE PPA, AND THE
ELECTRIC POWER INDUSTRY REFORM ACT (EPIRA)] November 7, 2011
subsidized electricity rates so their products can be more competitive especially against foreign
competitors.
With electricity subsidies, the government can encourage investment and thus increase
GDP. The resulting increase in demand for electricity will not only improve the demand curve of
the country which can lower the per KWh cost of covering the facilities to cover the peak
demand, but it can also dilute the market share of the largest suppliers of electricity. With
increased demand, other competitors can increase their market share and can thus lead to an
industry with a lower HHI. A lower HHI is needed to achieve a market structure that is closer to
perfect competition.
2. Remove oil and power from VAT coverage
If proceeds from VAT cannot be used to subsidize targeted industries, it should be
removed. According to the FDC, removing the VAT will effectively reduce electricity rates by at
least 0.80 Php/KWh. With this reduction, firms will be more competitive and households can
increase their consumption thereby increasing GDP.
3. Renegotiate IPP contracts
Although this has been done before, a new agreement is still possible to lower the
impact of the PPA.
4. Encourage investments in natural gas and geothermal power projects

The success of the Malampaya project automatically provides a bright picture for the
future of oil and gas exploration in the country. Government should craft policies that would
further encourage oil and gas exploration and infrastructure investments.
The Philippines is very rich in geothermal resources and this should be optimized.
Currently, the country is the second largest producer of geothermal power next to the United
States.
With investments in natural gas and geothermal power, the Philippines can effectively
decrease its dependence on imported coal and oil and this could help lower electricity rates.
