CE Delft advises cabinet to subsidize batteries in solar
Minister Jetten (Climate & Energy) today presented the House of Representatives with a letter sent which discusses the role of batteries in the energy system. It discusses the results of a CE Delft study on the role of batteries in overcoming generation congestion. The study concludes that batteries are the cheapest and most feasible option to reduce additional CO2 at times when there is less supply of renewable electricity. It also found that there is an uneconomic top for batteries that defer delivery. A subsidy could then help incentivize such batteries.
The recommendation to encourage batteries in solar PV fulfills the €416.6 million which the Cabinet set aside in the Spring Memorandum. The parliamentary letter shows that 160 to 330 MW of battery power can be realized with this budget. The cabinet thus considers it desirable for batteries to play a role in preventing or solving generation congestion.
Finally, the letter discusses TenneT's proposal for the introduction of a time-dependent transmission tariff, with which up to 65% can be discounted. On this wrote we rather that the proposal takes a nice first step, but does not achieve a breakthrough for energy storage.
