The Spanish government is planning to tax homes that produce their own energy through solar power and store some of it using batteries.
A draft decree prepared by the Industry, Energy and Tourism Ministry establishes a new fee to discourage the use of batteries or other storage systems by people who produce electricity, with solar or photovoltaic panels for instance, and who are connected to the national power grid.Only off-grid consumers may use batteries without being charged
Under the new rules, these self-reliant consumers will not be able to use products such as the Powerwall battery recently launched by American automotive and energy-storage company Tesla, and will additionally be penalized for the storage systems that come included with the latest generation of solar panels.
