Intersolar Summit Spain 2019 – Solar Growth in Spain brings New Opportunities for Energy Storage

At the Intersolar Summit Spain 2019 in Barcelona this week on the 18th of June the Solar community got together and discussed the national plan for energy and environment. This plan includes the target of Spain having 74% renewable electricity supply in 2030 which will include new PV installation of 28GW from 2020 to 2030. This means an installation of 2800MW of Solar in average each year from 2020 to 2030. Compared with the installation in 2018 of roughly 260MW this will be a huge increase for the next 10 years in Spain.

Most Common Business Model – PPA

Together with increased PV installation the opportunities for energy storage will rise. In Spain are great opportunities for Power Purchase Agreements (PPAs) according to Bruce Douglas, Deputy CEO and COO at SolarPower Europe. Within a PPA most commonly a price for the electricity purchase is fixed over a certain duration. But as presented within the Intersolar Summit there are many different possibilities for PPAs as presented by Nicolas Gourvitch (Founder of Green Giraffe).

Opportunities for Energy Storage – Merchant and Energy Shifting

Merchant

For example, together with PPAs, energy storage can bring benefit to Solar energy providers by storing energy in case the electricity price at EEX (European Energy Exchange AG) is lower than the contracted PPA price. This energy can be traded at the EEX in case the current price index is above the contracted PPA price. This is just one example for an application of a battery system combined with PV.

Energy Shifting

According to Raúl Morales (CEO at Soltec) there will be an overproduction of Solar energy during the midday, which results in an electricity price of zero or even negative values. This scenario will get more and more important with the raise of Solar power and brings huge potential for energy shifting with storage solutions like batteries. This statement was backed up by the Spanish TSO Red Eléctrica (presented by Paula Junco, Tecnico de la Dirección de Operacioines) for the winter months. There is a big potential for energy shifting although in the summer months the solar power will match the electricity demand in the near future.

Solar needs storage to compete in National Grid’s UK Capacity Market redesign

National Grid has outlined how renewables could participate in the UK’s Capacity Market, unveiling technology-specific de-rating factors that range from 1–15%.

However National Grid’s Daniel Burke warned that there remains a long way to go before renewables can participate in CM auctions, not least because of the need for policy reform.

Any introduction of renewable energy into the CM would require regulatory overhaul from BEIS and market regulator Ofgem, matters which, Burke said, mean it is “quite feasible” to “take some time”.

Wind, solar could be self-financing by 2025 under current European electricity market design

According to the Centre on Regulation in Europe (CERRE), Large-scale solar and wind power projects may already be able to compete in Europe’s wholesale electricity market in 2025. Lower capital costs for large-scale wind and solar projects, and much higher fossil fuel and carbon prices could lead to renewables becoming self-financing by 2025. If these conditions do not materialize, more auctions and tenders may still be needed.

In our opinon at cellution battery technology can help developing more economical models for wind and solar energy in the future and may enable renewables even befor 2025 to compete with conventional energy applications.
