High temperatures, clear skies and many hours of sunshine have meant that in recent weeks gas has lost prominence in the mix. In the first days of May, the electricity production of photovoltaic solar energy reached 20.2% of the total, according to Red Eléctrica data.
Even solar thermal, which is usually around 1.8% of generation, soared and produced up to 4. 2% of electricity on specific days. With the greater prominence of solar there is a phenomenon known as duck curve, due to the shape of the price of electricity in the market.
