Greek Ministry of Energy has identified an urgent need for battery integration into PV projects and it aims to incentivize such a combination by restricting PV tariffs offered at RES auctions for investors developing solar energy units with storage units.
The ministry fears prospective solar energy growth would have an unfavorable wider impact on the grid if PV projects develop at a faster rate than battery usage.
Solar energy farms are seen, by the ministry, as a key problem as they operate in a coordinated fashion, producing energy at the same time of day, regardless of where they are located around the country, whereas wind farms offer inconsistent output, day and night, which varies depending on their location.
Installed RES capacity growing at a faster rate than electricity storage would not only shrink available grid capacity but will also exacerbate RES cutbacks, made to prevent grid overloading, the ministry has noted.
