Which energy storage technologies are being commissioned in Finland?
Currently, utility-scale energy storage technologies that have been commissioned in Finland are limited to BESS (lithium-ion batteries) and TES, mainly TTES and Cavern Thermal Energy Storages (CTES) connected to DH systems.
How many electricity storage projects are there in Finland?
There are hundreds of electricity storage projects underway in various parts of Finland. Individual electricity storage facilities can range in size from tens to hundreds of megawatts, with a power requirement equivalent to the electricity consumption of a medium-sized city.
What is a capacity fee for grid energy storage?
The capacity fee for grid energy storages is a component similar to the capacity fee for power plants, and it is billed to the electricity storage facility for the sum of the rated capacity of its consumption and production power. For example, a 20 MW electricity storage facility is charged a capacity fee based on its 40 MW capacity.
Are electricity storage facilities billed only for energy taken from the grid?
Changes to the main grid fees for electricity storage facilities Unlike other network users, electricity storage facilities have been invoiced only for energy taken from the grid and supplied to the grid as part of their main grid service fees.
Which power storage facilities should be connected to the Fingrid network?
In the future, electricity storage facilities with a nominal capacity of more than 30 MW, which are to be connected directly to the Fingrid network, must be connected to the strongest nodes of the main grid, 400+110 kV or 400 kV substations.
When will Fingrid introduce a capacity fee?
In order to harmonise its pricing practices, Fingrid has decided to introduce a new component to the grid service fees, a capacity fee for grid energy storages, on August 1st, .
Changes to the main grid fees and connection principles for
For example, a 20 MW electricity storage facility is charged a capacity fee based on its 40 MW capacity. In , the electricity storage capacity charge will be €87.5/MW
