The document provides comments and suggestions on Massachusetts' proposed solar incentive program. Key points include:
1) Clarification is needed on how net metering rates will impact the viability of standalone vs. behind-the-meter solar and how PPAs would address changes to rates over time.
2) Metering, data reporting and incentive calculation requirements need to be established to accurately track generation from behind-the-meter systems and those with storage.
3) The program could discourage community solar projects if standalone systems receive higher incentives without community benefits.
4) Simpler alternatives like allowing buyers to purchase the incentive value upfront could reduce soft costs for behind-the-meter projects.

Utilities Global Market Report 2015 Released By The Business Research Company
http://www.thebusinessresearchcompany.com/our-research/utilities/utilities-global-market-briefing/
Utilities Global Market provides strategists, marketers and senior management with the critical information they need to assess the global Utilities sector.
The total value of the utilities sector globally in 2014 was $3,676 billion. Related to a world population of more than 7 billion in 2014 this equates to about $525 per person globally. Given that World Domestic Product was approximately $78 trillion in 2014, the market makes up about 4.7% of the global economy.
83% of households globally were supplied with electricity in 2013. Urban electrification was 95% whereas, rural electrification stood at 70%. The average annual rate of electrification in developing countries increased by 3.7% in 2014.
Global natural gas production was 3500 Bcm (Billion cubic meters) and grew by 1.6% in 2014. The highest level of natural gas consumption was by China (8.6%) followed by Iran (6.8%).
The utilities industry is one of the largest and fastest growing industries in the world. The term utilities refers to electricity, natural gas, water and sewerage services consumed by the public, hospitals, schools and other institutions, agriculture, factories and commercial establishments. In some countries these services are provided commercially by national, state or municipal governments or by cooperatives; in many, however, they are provided by the private sector.
Electric utility companies engage in the generation, transmission and distribution of electricity. They source coal from mining companies and heavy oil distillates from oil companies for power generation. Some also source power from sustainable energy sources and nuclear power stations for distribution. The power generated is transmitted over long distances to transformers in substations. The electricity from the substation is then delivered to commercial and residential customers, in some cases along a national or state grid. The market for electricity is often a regulated one. Natural gas businesses deal with the storage, transmission and distribution of gas. In this report we are dealing with the companies engaged in transmission and distribution of natural gas. Natural gas utility companies are either privately held or run by state/national governments. They source gas from oil and gas exploration companies for distribution. The gas is stored in storage tanks, then distributed through high capacity interstate and intrastate pipelines to households, commercial and business establishments and to power plants which use it for generating electricity. The market for gas is often a regulated one.

Evaluation of Utility Advanced Distribution Management System (ADMS) and Prot...Power System Operation
Practical and cost-effective communications solutions are needed to enable control of the growing number of integrated distributed energy resources (DERs) and grid-edge local aggregator devices such as home energy management systems. Each year, the total installed photovoltaic (PV) system capacity increases by an estimated 5 GW, over half of which is interconnected to the distribution system.1 PV’s increasing penetration—already accounting for the bulk of DER capacity—underscores the need to enable and manage its continued integration on the distribution system.2 Much previous work has shown that advanced distribution management systems (ADMS), which are effectively integration platforms for various grid control and visibility applications, can help enable the integration of higher levels of PV while also improving the overall performance and efficiency of the distribution circuit. Greater connectivity and controllability of utility- and customer-owned equipment increases the level of DER integration and overall circuit performance.3 The required performance of the enabling communications system, however, has been less thoroughly studied and is often greatly oversimplified in ADMS performance analysis. The availability of new technologies such as distributed sensors, two-way secure communications, advanced software for data management, and intelligent and autonomous controllers is driving the identification of communications standards and general requirements,4 but the link between the communications system and the expected performance of a utility-implemented control system such as an ADMS or other communications-reliant protective function requires further investigation.

Analysis of Electric Power Consumption using Smart Meter DataIRJET Journal
This document proposes an analytical model to analyze electric power consumption using smart meter data. The model consists of two modules: 1) A consumer-oriented module that clusters consumers with similar appliances and analyzes consumption patterns to provide customized recommendations for reducing usage. 2) A predictive module that uses historical consumption data to identify trends and predict future usage or irregularities. The proposed system first collects smart meter data, preprocesses it, then clusters consumers using k-means clustering based on appliance type and number. Consumption profiles are analyzed within each cluster to develop standards and suggest recommendations. Historical data is also used for predictive modeling and outlier detection.
Smart Grid Data Centers Distributed & ICTs Sustainability on Generation Energ...IJMTST Journal
Smart grid has modernized the way electricity is generated, transported, distributed, and consumed by integrating advanced sensing, communications, and control in the day-to-day operation of the grid. Electricity is a core utility for the functioning of society and for the services provided by information and communication technologies(ICTs). Several concepts of the smart grid, such as dynamic pricing, distributed generation, and demand management, have significantly impacted the operation of ICT services, in particular, communication networks and data centers. Ongoing energy-efficiency and operational expenditures reduction efforts in communication networks and data center shave gained another dimension with those smart grid concepts. In this paper, we provide a comprehensive survey on the smart grid-driven approaches in energy-efficient communications and data centers, and the interaction between smart grid and information and communication infrastructures. Although the studies on smart grid, energy-efficient communications, and green data centers have been separately surveyed in previous studies, to this end, research that falls in the intersection of those fields has not been properly classified and surveyed yet. We start our survey by providing background information on the smart grid and continue with surveying smart grid-driven approaches in energy-efficient communication systems, followed by energy, cost and emission minimizing approaches in datacenters, and the corresponding cloud network infrastructure. Through a communication infrastructure, a smart grid can improve power reliability and quality to eliminate electricity blackout.

2) Physically install submeters and current transformers according to manufacturer instructions while ensuring safety.
3) Commission the system by confirming accurate data, addressing any variances, constructing an optimization plan using submeter data, implementing the plan, and maintaining efficiencies through reviews. The goal is to maximize building value through precise billing, minimize utility usage, and optimize building intelligence.
Presentation by A. K. Bohra on Issues & Challenges in Net MeteringAnil Kumar Bohra
This document discusses net metering for distributed solar energy generation in India. It begins by providing background on smart grids and how they integrate renewable energy. It then discusses issues with integrating distributed solar generation through net metering, including metering and energy accounting, interconnection arrangements, commercial settlement processes, and applicability of regulatory instruments. Key challenges with net metering in India include the lack of standardized policies and technical standards. The document argues that developing comprehensive standards and policies can help address safety concerns while also opening new business opportunities in the growing distributed solar energy sector in India.
The utility landscape is dynamic. Some pundits claim that traditional utility regulation is becoming obsolete. Others are calling for a complete overhaul of utility ratemaking as we know it; distributed energy resources, technology advancements and societal trends are changing the way utilities function. In such turbulent times, how can utilities manage their financials through rate structures? How can utilities bridge the span between the rate and regulatory frameworks of yesterday and tomorrow? One way to do so is to revisit the design of rate offerings available to all utility customers and to residential customers in particular.

The American Public Power Association’s “Rate Design for Distributed Generation” report examines rate design options for solar and other distributed generation (DG), using public power utility case studies. The report discusses how utilities have educated customers about new rates, and how DG
and non-DG customers responded. While the rate design options have some drawbacks, and might not be technically feasible for all utilities, they offer the industry new models that account for the rate impacts of distributed generation.
The use of DG, particularly rooftop solar photovoltaic (PV), is growing fast. As of October 2014, just under 8,000 megawatts (MW) of solar capacity was installed on residential and business rooftops across the United States (U.S.).1
The growth of DG has been spurred by environmental concerns and economic considerations. Federal and state tax incentives are a driving force behind solar PV installations
and can together cover up to 70 percent of the total cost of solar panels in some states.2 Declining solar panel prices have also fueled growth in rooftop solar. Utility rate structures for distributed generation have provided a significant benefit to solar customers.
As DG becomes more widespread, rate analysts and researchers are developing new rate designs to help ensure that utilities recover their cost of service, encouraging while providing appropriate incentives for rooftop solar deployment.
Utilities can no longer afford to take a wait and see approach in rate design for DG, nor should they assume that old rate designs adopted before the escalation in DG installations will work in the future.
Most utilities in the U.S. use net metering to measure and compensate customers for the generation they produce. However net metering has several shortcomings and results in non-DG customers subsidizing DG customers.
Utilities have options other than traditional net metering. Many public power utilities have adopted new rate designs to serve DG customers. Some of these rate designs supplement net metering by recouping more of their fixed costs through fixed charges, while other designs provide comprehensive alternatives to net metering.
Utility rate setters must balance between simplicity and accuracy, align costs and prices, support environmental stewardship, and ensure that rate designs are well suited to customers. Customer communication and engagement are essential components of the rate-setting process.
This report does not examine every rate design option, nor does it suggest a single best option. It offers alternatives
to traditional net metering, with case studies. Utilities
can consider how they can adapt rate designs to suit their community’s needs, factoring in market structure, state policies, and other considerations.

The document discusses Con Edison's support for solar and storage projects seeking interconnection in New York City. It outlines the various teams within Con Edison that support interconnection via project management, engineering, policy initiatives related to renewable energy goals, and operations. The agenda then highlights specific programs and processes Con Edison will cover, including non-wires solutions, demand response participation, electric vehicle programs, and the EV interconnection process.
Case Study: Blockchain as the Foundation of Alectra's Grid Exchange Transacti...Jill Kirkpatrick
GridExchange is a blockchain-based platform being developed by Alectra Utilities to facilitate energy transactions. It will enable three key services - managed electric vehicle charging, CO2 reduction incentives, and demand response. The platform is designed to provide benefits to end users, utilities, and other stakeholders. It will leverage robust data analytics and governance to improve grid reliability, lower costs, and empower customers while maintaining privacy. Success will depend on continued growth of distributed energy resources and regulatory support for non-wired alternatives.
This document summarizes a webinar on net metering policies for tribes. It defines net metering as allowing electricity customers who generate their own power to send excess electricity back to the grid. It outlines key components of net metering policies like system size limits and credits for excess generation. It provides examples of net metering programs and discusses debates around the appropriate rate for crediting solar generation. The webinar aimed to help tribes understand net metering policies to inform renewable energy projects.
This document provides guidance for consumers considering investing in a solar photovoltaic (PV) system. It discusses factors to consider such as system sizing, location, incentives available and costs. The best location for a PV system is a south-facing roof that receives maximum sunlight with no shading obstructions. State incentives like rebates and net metering can help reduce the upfront costs, though PV remains more expensive than grid electricity initially. Careful planning is recommended to ensure a PV system is right for the home or business.
This document provides information about solar electric or photovoltaic (PV) systems for homes and businesses. It discusses what a PV system is, how it works to convert sunlight into electricity, and its key components. It also notes that several states offer financial incentives like rebates, net metering programs, and tax incentives to help reduce the cost of installing a PV system. Net metering allows customers to receive full retail value for excess electricity generated by their PV system and sent to the electric grid.

Solar peco my generation customer report rooftopJason Shragher
This document summarizes a report on the potential for rooftop solar panels at a property located at 27 Redwood Dr, Richboro, PA. It estimates that installing a 10.5kW solar system would cost $26,900-$32,900 upfront but qualify for incentives reducing the cost to $23,300. The system would offset 25% of the property's electricity usage and have a payback period of 35 years based on electricity savings and assumed annual rate increases of 2%. It also estimates the environmental impacts of offsetting over 12,000 pounds of carbon dioxide emissions annually.

3. Standalone (Ahead Of The Meter)
1. Which “net metering” rate will be used?
Within a utility territory, more than one “net metering” rate may be
used for standalone systems
o E.g. Eversource – NEMA: A9 (General without Demand Meter) or B5
(Optional Time of Use )
Value of PV energy generated can vary by several cents / kWh
depending on the rate
Rates may be subject to changes that could incentivize standalone
PV to switch rate classes
3
4. Standalone (Ahead Of The Meter), cont..
2. Standalone net metering rate may exceed Tariff rate
E.g. Eversource-NEMA weighted-average standalone net metering
rates have been in the $0.20 to $0.25 / kWh range.
o Proposed Illustrative Tariff Values for > 250 kW-AC lower than net
metering value
o With any increase in delivered energy costs, standalone net metering
rates likely to rise also
o If net metering services are available, why would a PV participate
in the new solar program if they expect the net metering rate to
exceed the new tariff?
If standalone net metering value exceeds tariff, there will be an
incentive to install standalone PV over behind the meter PV
o This does not appear consistent with the new program’s goals
4
5. Standalone (Ahead Of The Meter), cont..
3. Incentive structure may complicate the terms in Power
Purchase Agreements (PPAs)
Typical arrangement has been:
o Developer keeps SRECs
o Off-taker pays flat rate, or rate with preset escalation, to developer for
20 years
Known energy rate is a big PLUS!
o Off-taker gets full benefit of net metering credits
Under proposed new program
o When net metering rate goes up, the value of the incentive goes down
If a developer takes the incentive (e.g. like SRECs, now), how do they
protect themselves from this risk?
• Indexed PPA rate? (Do Off-takerss loose the comfort of knowing what the rate will be?)
• What if net metering rates (small commercial class) are modified (by DPU)
substantially? How does the agreement deal with this situation?
5
6. Standalone (Ahead Of The Meter), cont..
4. Merchant PV vs. Off-taker PV
As the new program design caps the combined value of net
metering, or sale to utility as a QF, and Incentive:
o Why would a developer bother to negotiate a PPA with a
municipality or other Off-taker?
• Assuming the value of the net metering credits does not exceed the Tariff.
• The Tariff rate is the same under either case, but,
Under the PPA, the developer will need to share some of the benefits with the Off-taker
(e.g. municipality)
Under a PPA a lengthy RFP proposal, contract negotiations, etc.. may be required
If sited on public land, a land-lease only agreement likely to be easier to obtain
• As a QF, they can keep all of the benefits without the hassle/risk of securing a PPA
agreement
Will solar with Off-takers (primarily public) for landfills,
brownfields, parking lots, etc.. be a thing of the past?
If so, does this endanger “community” and local support for solar?
6
7. Behind The Meter
1. Who owns the solar production meter?
The behind the [utility] meter, “meter”
Installed on customer side of electric system, prior to grid interconnection
point
Measures solar generation prior to consumption by load
Frequently used with a Data Acquisition System (DAS) to report generation
remotely and also track PV performance
If utility owned,
Will utility have meter accuracy requirements?
Would current meter / DAS vendors supporting the SREC market meet these
requirements?
Could they integrate their DAS systems with the utility meter?
Will there be any liability concerns for the utility in having equipment on the
customer side of the electric system?
Whose responsible for the accuracy, testing and calibration of the meter?
If customer owned,
What, if any meter requirements are there?
How do the utilities collect the meter data?
7
8. Behind The Meter, cont..
2. How does generation data get to the utility?
If meter is utility owned, utility meter reading system records
generation
If meter is customer owned,
Production Tracking System (PTS)?
Currently used to track PV generation for SRECs
How does the utility access the information and link it to specific utility
accounts for Incentive calculation and processing?
PTS/ NEPOOL-GIS
Like SREC market, aggregators buy rights to Incentive attribute from PV
owners, aggregate generation, then sell to utilities.
The base electric rate associated with the PV will need to be tracked through
the sales chain to establish the Incentive associated with the PV.
Does a new class of “attribute” need to be added to the GIS system to
accommodate this? If so, how long would it take to get this set up?
What are the soft cost implications?
8
9. Behind The Meter, cont..
3. Special consideration for PV with storage
Systems with storage will have energy losses associated with storing
and retrieving energy
o To ensure storage PV systems are sufficiently incentivized, should a factor
(e.g. X 1.1) be applied to the generation reported?
AC coupled storage systems may already have a solar production meter installed
after the PV inverter but prior to storage, so no factor may be required
DC coupled systems
• May experience significant loses prior to solar production meter
• Some PV storage systems may require two (2) behind the meter, meters to accurately track
generation, and manual calculation of the result (e.g. as currently experienced with Outback
residential PV with storage systems)
Energy Resiliency (backup power) systems may require a higher
incentive than Peak Shaving Systems
o For energy resiliency the idea, is to keep the “tank” full to serve in an
emergency
o Peak shaving burns the tank during certain hours to save money and will
likely achieve a higher value for each kWh of energy generated by the PV
9
10. Behind The Meter, cont..
4. What’s the Base Rate?
For rate classes that have demand based T&D charges in lieu of
energy based T&D charges, what is the rate to be used in the
incentive calculation?
o “All in” - i.e. total $ charges divided by kWh used in a month.
o Would likely be unfair to those on utility commercial accounts
• Max PV generation does not often occur at the peak demand time, thus rates that have T&D
demand charges are not optimal for PV
PV can not capture full value of rate
As opposed to an energy (kWh) only rate
o Supply only – i.e. does not include T&D charges
• Conceptually easier, but would this meet the statewide program goal?
Adjustment for PV at sites that have a supply contract (e.g. energy
choice)?
o Energy rate may be substantially higher or lower than utility default rate
o If supply and T&D bills not consolidated, how does utility get supply rate?
PV sited in municipal aggregation area?
10
11. Data Aggregation and Incentive
Management
1. Who does the math?
For Standalone PV, utility has both the generation and net metering rate for
a specific PV – meter and rate are linked together under the utility account
o Can process of deriving incentive be automated, (e.g. [Tariff Rate – Net Metering
Rate]* kWh) ?
o If not, how many PVs will need to be manually calculated and processed each
month?
For Behind The Meter PV
o Could MassCEC do the math?
• Generation data and utility rate need to be linked by someone
• Does PTS track utility account numbers?
• Could PTS track rate class?
2. Who cuts the checks to PV?
Utilities?
MassCEC on behalf of the utilities?
Aggregators (e.g. like current SREC brokers)?
11
12. Community Shared Solar
1. Comments on CSS Definition
Per, “No more than two participants may receive electricity or
net metering credits in excess of those produced annually by
25 kW AC capacity,”
o Could be an ambiguous benchmark
• How much energy (kWh) does the 25 kW-AC benchmark generate? What
are the design details and equipment specifications? What generation
projection tool should be used (e.g. PV Watts), what weather file?
• Simpler approach perhaps: “No more than two participants may have a share that
exceeds 25 kW AC of nominal rated inverter capacity as calculated by: Share(%) *
Total Project Inverter Nominal Rated Capacity.
Nitpick: as written, may be perceived as excluding some forms
of CSS, e.g. when the net metering host customer is the
“community”
o Suggest modifying language to: “…in the form of formal ownership, a
lease agreement, a retail supply contract, [power purchase
agreement] or a net metering contract.”
12
13. Community Shared Solar, cont..
2. Comments on Retail Supply Contract Option
Is this CSS, or more akin to a green power program?
o Is this the same as offerings currently available with a mix of wind, hydro
and biomass? Except the technology is solar?
o What is the “community” and how is the PV “shared?”
• Power buyers co-op?
• Will DOER promulgate minimum solar content requirements?
o Will it always be possible to be 100% solar? (e.g. in winter months?)
o If not, what’s an acceptable minimum content?
o Could an offering that had 50% and 50% other renewables participate at
a prorated (50%) level in the program?
13
14. Program Design Suggestions
1. Standalone Net Metering PV
Why bifurcate net metering and the incentive?
o Total of the two is capped
o Both have utility cost recovery
o Doing the math of calculating the incentive adds cost / complexity
o Simplify math: Value = energy (kWh) * Tariff Rate
Elective distribution of incentive
o Host Customer decides what percent of value will be credited to electric
bills (through a modified Schedule Z) and what portion will be paid in
cash
• E.g. customer wants 50% of value as a credit on electric bills, and 50% to go
as cash to third-party PV owner
o Should help simplify PPA / Net Metering Agreements and reduce
administrative burden for the utilities, help program roll out sooner
14
15. Program Design Suggestions, cont...
2. Behind The Meter
To reduce administrative burden and soft costs, allow behind the meter PV a
buyout option
o One-time payment from utility to PV owner to purchase 10 years of Class 1 RECs
(i.e. the Incentive payments)
o PV generation is projected for 10 years (using a prescribed method) and utilities
are able to claim the RECs associated with the generation in each year
o Tariff set based on the expected cost of a behind the meter PV system and
expected benefits with reasonable payback period
o Tariff may vary by utility territory to account for lower or higher costs and benefits
o Policy and other adders can be included
o PV sites may be subject to audits or other means to verify generation, must
maintain approved meter or means to track generation
o Annual or bi-annual evaluation of program can determine whether actual
generation is in line with projected generation
o Meter reads from sample of PV sites sufficient for 80/20 confidence (or higher) used to
document annual generation – approach similar to that used verify benefits of energy
conservation programs
o Results calibrated to account for insolation experienced during the year
o If projections are higher or lower than actual generation, then projections can be adjusted as
needed
15
16. Program Design Suggestions, cont...
2. Behind The Meter, cont..
Benefits of Incentive Buyout for Behind the Meter
o Easy to adjust Tariff with each block or as needed to account for changes in the
market
o Incentivizes Behind the Meter versus Standalone (i.e. money now, instead of in the
future)
o Should reduce administrative burden and soft costs
• No need to calculate the incentive on a monthly basis for each site
• No metering or rate class issues to contend with
o Should mesh nicely with Solarize programs and the Mass Solar Loan program
• Lower loan amounts required – means less interest to pay
o Faster program startup time – no need to construct business / metering / billing
systems to get metering data to the utilities and process it
o MLPs could readily utilize the program while proving funding for the PV in their
territories
• MLPs could set their own incentive levels
• MLPs could accrue Class 1 RECs and sell them to recoup program costs
Income Tax implications
o Program should be designed to allow the PV owner an option to treat the Buyout as
non-taxable, or taxable, depending on which approach minimizes their taxes
16
17. Program Design Suggestions
3. Incentivize Off-Taker PV over Merchant PV
Why is an adder for non net-metered Standalone systems needed?
o The structure of the Tariff appears to level the playing field between net-metered and non net-
metered PV
• Why is an adder needed?
o Won’t this encourage solar developers to sell power to the utility?
• Why would they respond to an RFP released by a community?
More cost and hassle for less financial benefit
Why go behind the meter, if better value as Merchant PV?
o No energy savings for communities?
• No community participation?
• Will solar be industrialized with no substantial community participation?
Suggestion – add requirement that to take the Adder there have to be Off-Takers in
some form
o Energy benefit needs to show up on an electric bill
Suggestion 2 – allow Behind the Meter PV to take an Adder if they aren’t net
metered
o Not necessarily at the same level as for Standalone
o Otherwise might incentivize Standalone over Behind the Meter when no net metering
services are available
Nitpick: should the Chart on Slide 23 of the Straw Proposal (Large System Tariff
(Qualifying Facility)actually show the Tariff at $0.20 instead of $0.15
o $0.15 Base + $0.05 Adder
