21. The energy consumption during 2012 reached: 132 GWh and it should reach
1.750 GWh by 2020.
The energy consumption of hydraulic infrastructure is quite variable as it
relies on the availability or not of water resources and associated water
demand this graphic is also an estimation for the next years.

25. As State Society Acuamed is subject to the Spanish Law for Contracts of the
Public Sector, in particular to the “Texto Refundido (TRLCSP)” approved by
Real Legislative Decree 3/2011, of November 14th 2011.
The TRLCSP tries to guarantee the free concurrence and the
transparency of the bidding procedures.

variability.
therefore its price has a great
The TRLCSP does not include procedures allowing to optimize the purchase
of energy.
The procedures used for the purchase of energy may be:
•Auction
•Open procedure
•Agreement
•Negotiated with publicity

26. Acuamed uses the negotiated bidding with publicity which is only allowed
for exceptional reasons.
In this case the exceptional nature of the contract to bid comes from two
aspects:
•A part of the price of the energy is regulated by the Ministry of Industry,
Energy and Tourism, and it is impossible to know its modifications in
advance.
•The consumption of the energy in a certain period of time is not known
beforehand, since it is subject to circumstances out of control of the State
Society.

27. Characteristics of the bidding:
Acuamed requires to bidding companies to provide a minimum of 750GWh
in a year
The term of the contract is 12 months.
The modality of the asked for supply is of fixed price.
A technical offer with the following content is requested:
•Procedures to solve incidences of invoicing
•Flexibility of the demand and management of the consumption
•Description model for the information for flexibility of demand
•Proposal for consumption management
•Improvements and additional services

28. The main landmarks of the hiring procedure are:
1.Opening of the administrative documents
2.Invitation to present the technical and economic documents to the
admitted companies
3.Opening of the technical documents (Act witnessed by public notary)
4.Technical Valuation
5.Opening of economic proposals (Act witnessed by public notary)
6.Economic and total Score
7.Beginning of the process of negotiation with the three companies with
the higher scores
8.Proposal of awarding to the Society’s Office

29. The valuation of offers is made with the following criteria:
Technical offer: 20%
14%: Proposals of flexibility of demand
3%: Additional proposals of improvements and services
2%: Model, content and frequency of information
1%: Systematic resolution of invoicing incidences
Economic Offer: 80%

GREEN ENERGY FOR INFRAESTRUCTURES FINANCING

31. Acuamed gives great importance to energy supply coming from cogeneration and renewable power plants of high efficiency. The Spanish
Regulation is based on: Order ITC 1522/2007, related to high efficiency, and
Order ITC 2914/2011,a modification of the previous which incorporates article
15 of the 2009/28/CE.
How is green energy considered in the bidding of energy supply of
Acuamed?
The provision of green energy is not a requirement of forced fulfillment.
It is considered in two ways:
• A specific chapter in the technical offer: where each distribution
company can offer a certain % of green energy, obtaining an additional score
of up to 5 points.
• Each distribution company decides its influence on the economic offer.

32. The Regulating Clauses establish:
•The amount of green energy supplied must be clearly specified in the
economic offer.
•The distribution companies must certify the percentage of energy coming
from renewable sources or co-generation of high efficiency that are
going to be provided to Acuamed throughout the contract.
•At the end of every natural year the awardee must certifiy the amount of
green energy supplied according to the regulation established by the
National Commission of Energy. If the awardee fails to fulfill the commitment,
and certifies less than 80% of its commitment, a penalty equivalent to 0.3%
will be applied to him on the invoiced total price.

33. Regulating Technical Clauses award:
5 points awarded to the 100% of the green energy
2 points will be awarded in between 75% and 100%.
1 point between 50% and 75%.
The actual result of this bidding formula is that the 100% of the energy
supplied to Acuamed comes from renewable energies since January 2010,

34. The incidence of the 5 additional points is higher than might be thought at first
sight:
The differences in the scores of the technical offer are usually around 2
points.
The differences in the scores of the economic offers are usually between 12
and 20 points.
This means that the 5 points obtained from the provision of green
energies represent 25 or 35% of the difference of scores.

GREEN ENERGY FOR INFRAESTRUCTURES FINANCING

36. There is an increasing need to look for external financing for the construction
of great hydraulic infrastructure.
On the other hand, the environmental aspects in the infrastructure financing
are more relevant.
On June 4th 2003, 10 bank leaders, from of seven countries, adopted the
“Equator Principles”, that represent
a series of directives for the
management of social and environmental aspects assumed by those banks
for the financing of great international projects.
The Equator Principles are based on policies and directives of the World
Bank. Nowadays as much as 79 institutions have joined that agreement.
The banks require promoters that ask for financing to fulfill those principles.

37. 5.- GREEN ENERGY FOR INFRAESTRUCTURES FINANCING
The Equator Principles are:
Principle 1: Review and Categorisation
Principle 2: Environmental and Social Assessment
Principle 3: Applicable Environmental and Social Standards
Principle 4: Environmental and Social Management System and Equator Principles
Action Plan
Principle 5: Stakeholder Engagement
Principle 6: Grievance Mechanism
Principle 7: Independent Review
Principle 8: Covenants
Principle 9: Independent Monitoring and Reporting
Principle 10: Reporting and Transparency
The use and generation of Green or Alternative Energy may be among
these principles

38. 5.- GREEN ENERGY FOR INFRAESTRUCTURES FINANCING
In the case of Acuamed, the state society has subscribed a credit of 500
million euros with the European Investment Bank for the construction of
hydraulic infrastructure.
The policy of the EIB for the financing of projects incorporates, as one of the
key points, the power management of the projects, valuing significantly the
use of renewable energies, as well as power efficiency.
In this sense Acuamed has implemented an Action Plan intended to:
Give advantage to renewable energies: photovoltaic plants and
hydraulic energy.
Power audits in the facilities of greater consumption.
Power improvements by means equipment modernization.
Use of renewable energies.
