Batteries: The jack of all trades
The EU 2020 energy and climate targets have led to a significant increase in the share of renewable energy sources in the EU’s electricity supply mix. Going forward, EU’s ambitious goal of reducing the greenhouse gas emissions by at least 80% of the 1990 value by 2050 indicates that this growth in renewable generation can be expected to increase over the coming years.
A power system based on renewable energy needs flexibility to balance demand and supply. OFGEM defines flexibility as “modifying generation and/or consumption patterns in reaction to an external signal (such as a change in price, or an electronic message) to provide a service within the energy system”.
