The new plan increases the Spanish government's energy and climate ambitions across the board, setting higher goals for solar and wind power, among others. Energy is a hotly debated topic in Spain ahead of national elections next month, with the front-runner, the opposition People's Party (PP), pushing to extend the life of its nuclear plants.
The revised plan sets a 2030 target of 11 gigawatts (GW) of electrolysers, up from a previous target of 4 GW. It also plans to double the target for biogas production to 20 terawatt hours (TWh).
By 2030, Madrid wants to cut greenhouse gas emissions by 32% from the level in 1990. The previous target was 23%.
The document is a draft that may still be amended.
The plan also increases targets for wind generation capacity, to 62 GW from a previous 50 GW, and photovoltaic generation capacity to around 76 GW, and power storage capacity to 22 GW.
A spokesperson for the Energy Ministry declined to comment.
Spain, like its European peers, faced an end-of-June deadline to submit the draft updated plan to the European Commission. The final text is due by June next year.
