  • The main energy consumption is due to:
  • The actual power contracted by Acuamed is : 145 MW. This is the evolution of power contracted and a middle term estimation, we will reach 300 MW by 2020: 2011 2012 2013 110 MW 145 MW 195 MW ... 2020 305 MW
  • 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. 2011 2012 2013 100 GWh 132 GWh 354 GWh ... 2020 1.700 GWh
  • Acuamed has at the moment 131 supply points.

  • 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. The electrical energy quotes in markets 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
  • 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.
  • 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
  • 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 Societys Office
  • 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%

  • 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.
  • 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.
  • 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,
  • 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.

  • 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.
  • 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
  • 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.
