We are what we do every day

Renewable Energy

Our trajectory begins in 2001, focusing at that time only on wind energy, and entering as collaborating partners in APPA and APPA Eólica Catalunya. From this section we were co-drivers of Eolicat. In the following years we remain very active in transactional advice, and from 2005 we expanded to photovoltaic technology, accompanying foreign component manufacturers and also photovoltaic plant developers in their processing, Due diligence and financial structuring. In these first years our career is mainly focused on Renewable Energies, and their remuneration and permiting.

Creation and consolidation as an independent firm

In 2008 our firm was born as an independent entity, and a purpose-driven company. These are years of much growth in the renewable energy sector and our firm grew along. We extend our advice to other renewable technologies such as biomass and hydraulics. In this period we started our blog about the evolution of industry regulations, which creates a lot of interest in our firm. Soon we consolidated as an independent firm, having companies of great relevance among our customers.

Legal Defense

From the retroactive changes of the years 2010 – 2014 we deployed a collective defense of photovoltaic, wind, hydraulic, cogeneration and biomass producers and the APPA itself. We litigate up to the Supreme Court and the Constitutional Court, the European Court of Human Rights in Strasbourg, a procedure for annulment of State aid before the General Court of the European Union, a cassation of the same before the Court of Justice of the European Union, and in two proceedings preliminary questions representing more than 3,500 generation facilities.

Since the beginning of self-consumption with the Royal Decree 1699/2010, but even before, when it was legalized simply in low tension, we have advised in distributed generation. The European Commission, following our defense in the European Parliament, before its petitions committee (PETI), made a critical follow-up of self-consumption in Spain, during the years of reactionary government on issues of energy transition.

Journey across the desert

We initiated 7 infringement proceedings before the European Commission, and we ended up suing the European Commission itself before the General Court of the European Union and in cassation before the European Court of Justice. In the European Parliament’s Committee on Petitions, we defend our demands for retroactivity and self-consumption. This case has been pending since 2021 before the Spanish National High Court, and a preliminary question has yet to be referred.

In 2013, we participated in the meeting of recycling experts and/or second life batteries. Since then, we have advised on different projects with batteries. The most recent, and in which the partners of our firm are the drivers, is EquanimityEnergy, electric vehicle charging project with proximity renewable energy and storage systems to ensure optimal 24/7 supply.

Hot and cold grids

In 2014 we were commissioned the first legal consultancy to implement a district heating between various industrial estates. Over the years we have carried out this type of advice also for public entities such as the management of the district heating municipal network of Molins de Rei, among others.

In 2015, Eurosolar awarded us the Eurosolar prize for our tireless defence of the energy transition. Finally, in 2020, a regulation is approved that forces the abandonment of these causes before the threat of destabilizing the remuneration of these facilities in the future. We advised our customers to accept it, although a customer wanted to follow. We are still waiting to refer the latter procedure to the European Court of Justice by way of a preliminary ruling.

From 2016, PPAs began to be negotiated in Spain, due to the grid parity that was reached in this year. We have advised on PPAs of all types, for a wide variety of clients. From large volumes of almost 80GWh per year to PPAs for installations of only a few MW. We have done it for generators, marketers and consumers, large and small. We also help in neighbouring issues such as access and connection, financing contracts, guarantees, project finance, bonds, structured finance etc.

Self-consumption at last

As requested by ICAEN we have led the self-consumption table in Catalonia. Since the winter package of the European Commission we have advised a multitude of companies, public administrations and public companies on self-consumption, such as the Diputaciones de Lleida and Girona, the Area Metropolitana de Barcelona, Barcelona Energía, Infraestructures de Catalunya, the Govern de Balears, the Climate & Energy Foundation in Valencia, and INCASOL, to name just a few. As well as a large number of private clients, the companies associated with the sector organizations to which we belong usually have our expertise.

In 2018, we launched the idea of self-supply, a configuration that resembles a remote consumption. In the years 2021 and 2022 they have had special impact on our advice on the intervened wholesale market.
