On Friday, December 14th, we will attend the V General Assembly and round table on energy storage of the RIS3CAT community. Along with AEPIBAL, the Business Association of Batteries and Storage, will be present at the round table where different projects will be presented and will discuss future challenges in research and development on energy storage in a broad view: from batteries for electric mobility or self-consumption, chemical storage or integration in distribution networks.

The event will take place on December 14th from 08:45 a.m. to 12:15 a.m. in the ACCIÓ Conference Hall (Passeig de Gràcia, 129. Barcelona). You can access the complete information and the registration form of this appointment here.


On Thursday, December 13th, will take place at the Hall of the Palau Robert Cotxeres in Paseo de Gracia number 107, Barcelona, a key event for self-consumption: the 2018 Plenary Meeting of the taula d'impuls to l'autoconsum fotovoltaic de Catalunya . This initiative, sponsored by the ICAEN whose legal working group leads our firm, seeks to facilitate and promote self-consumption in Catalonia. Self-consumption is destined to play an essential role in the energy transition, and should help decisively to meet the ambitious targets set in the Catalan Law 16/2017 of climate change.

This coming Thursday, 26 March we will be attending an event in Girona titled "Implantació de l’energia solar fotovoltaica amb autoconsum en els municipis" ("Promoting Photovoltaic Self-Consumption in Local Government"). The event's objective is to identify, on the one hand, the opportunities and application processes necessary for the development of photovoltaic installations by local government entities, and on the other hand, to discuss how to remove administrative barriers with respect to private photovoltaic installations. The event will also provide a summary of the results of a study into the integration of charging points for electric cars and photovoltaic installations installed on buildings, along with a discussion of potential sources of assistance and financing.


The event is designed principally for employees of local governments.


Piet Holtrop will participate in the conference as speaker in a session titled "All that local governments need to know about self-consumption" ("Tot el que les entitats locals han de saber sobre l'autoconsum").


We will provide the complete event program and the registration details as soon as they are available.

On 22 January 2018 the UNEF PPA Working Group will meet. UNEF has a variety of different working groups in which prestigious professionals from different backgrounds meet to discuss the issues of most relevance to the photovoltaic industry.

Without a doubt one such issue is the rise of bilateral contracts for the sale and purchase of energy, also known as PPAs (Power Purchase Agreements). PPAs are destined to contribute decisvely to the development of new photovoltaic projects. Amongst other reasons for this is the fact that these contracts assist greatly in the financing of projects, given that they allow for a diversification of the income streams available to developers, such that electricity can be sold directly to pool, individually to a specific purchaser, or as a type of financial instrument to minimise exposure to volatile electricity prices.

Piet Holtrop will present on the principal aspects to take into account in these agreements from a legal point of view.




On Thursday, 22 February 2018 the EolicCat General Assembly will take place. EolicCat is the wind power association of reference in Catalonia, an association of which we are members. Piet Holtrop will attend this event, in which some of the key decisions for the development of the wind power sector in Catalonia will be taken, and which will also discuss PPAs. Piet Holtrop is invited to comment one the legal aspects of this type of bilateral energy contract.

At 13.30 Piet Holtrop will speak on recent modifications to the 'Charging Manager' ("Gestor de Carga") figure under Spanish law. These changes are essential for the development of the electric vehicle in Spain and Catalonia. Piet Holtrop's presentation will provide an overview of these modifications and whether or not they go far enough in the context of electric mobility scenarios in the future. On 24 November Piet Holtrop recently published an article on the topic.
