The relationship with our clients: beyond retailing electricity from renewable sources, we share a common purpose

We provide all types of effective resources and tools to cater to your energy needs, with a highly practical focus on rational consumption, improving business competitiveness, sustainability and the strengthening of environmental and societal policies. In other words, a focus on designing a better planet.

Services for you

Demand management

The focus of energy demand management is on how each client consumes depending on their business sector.

Adjusting demand to actual needs by optimising the use and operation of renewable energy facilities and taking advantage of the most efficient technologies available allows for energy consumption to be reduced and energy supply related costs to be lowered.

Energy efficiency

Corporations and companies committed to the conservation, efficient use and proper management of energy require a strategy that allows them to establish and achieve consumption reduction and environmental impact goals.

Energy efficiency is fundamental to reducing energy consumption and, therefore, is aimed at cost reduction, improved competitiveness, reduced CO2 emissions and the improvement of related renewable energy processes, equipment and facilities. This improved use of energy can be supplemented with the generation of your own renewable energies or by third parties.

Therefore, energy efficiency entails net economic benefits and is the best option for reducing emissions together with the use of renewable technologies.

Public aid and subsidy management

Before starting any renewable energy project, talk to our team of experts about lines of public funding within the renewable energy and energy efficiency development plans.

We have a professional team to give you specific advice on the availability of public aid and provide information on existing public alternatives and the necessary requirements. We are here to guide you every step of the way.

Energy management systems consulting

The aim of the UNE EN ISO 50001: 2001 standard is the promotion of energy savings, energy efficiency and the reduction of greenhouse gas emissions through the establishment, implementation, maintenance and continuous improvement of an Energy Management System.

The internal and external communications of an Energy Management System, like an environmental or quality management system, are a commitment by ACCIONA aimed at strengthening its competitiveness through the rational use of energy: the maximum expression of a responsible commitment to the environment.

Integrity and transparency in the energy Wholesale Market.

The Energy Division of the ACCIONA Group (henceforth ACCIONA), which participates in the Iberian Electricity Market through its subsidiary company ACCIONA Green Energy Developments S.L.U., subscribes to the principles stated in EU Regulations No. 1227/2011 of the European Parliament and Council (REMIT). The aim of this regulation is that consumers and other participants in the market can trust the integrity and transparency of the wholesale energy market, these being the spot and long-term markets with physical or financial settlement for electricity and natural gas in each of the Member States.

The prices set in the wholesale energy markets should reflect a fair and competitive interaction between supply and demand. To achieve this, REMIT lays down rules that prohibit abusive practices and an obligation to report operations made in the different markets to ACER (European Agency for the Cooperation of Energy Regulators).

REMIT also establishes a specific legislative framework for the supervision of the wholesale energy market, promoting coordination between ACER and the national regulatory authorities in order to carry out this supervisory function.

ACCIONA supports this initiative and complies with the terms of the abovementioned Regulation. It provides, in the greatest possible detail and in advance, information on the availability of its generation portfolio and operations made in the markets, with a view to encouraging transparency and facilitating competition in energy markets.

Prohibition of abusive practices

Specifically, REMIT establishes prohibitions on insider trading and any attempts to manipulate – or try to manipulate – the market, plus an obligation to publish insider information.

In its Internal Code of Conduct in Wholesale Energy Markets ACCIONA Green Energy Developments S.L.U. includes rules to set up suitable checks related to Insider Information and the preparation or performance of practices that may affect the free formation of prices or involve other kinds of actions that could represent a manipulation or abuse of wholesale energy markets.

ACCIONA Green Energy Developments S.L.U. provides the information indicated below, subject to its review and updating by the company in compliance with current legislation.

  • Final matching program in the electricity market (P48).
  • Programmed and non-programmed availability.
  • Portfolio and generation capacity of ACCIONA.  Please consult these.

Registration requirement and reporting operations

REMIT establishes a requirement for participants in the wholesale energy market to register with the national regulatory authority of the Member State in which they operate or, in the case of operators who are not established or are domiciled in the European Union, with the authority of a Member State in which they operate.

From October 7th 2015, participants in the wholesale energy market, either directly or through a person or entity authorized to act on their behalf, are obliged to provide ACER with a list of operations carried out.

For this purpose, ACCIONA – through its subsidiary Acciona Green Energy Developments S.L.U., a participant in the Iberian Electricity Market (MIBEL) and the OTC market − reports its operations in the futures market and has contracted the services of OMIE to report the operations carried out in the MIBEL.
