Approximately €2m is being invested into the energy storage facility, with 30% of the required funding being covered in the form of aid from Finland’s Ministry of Employment and the Economy

In Northern Europe, Finish electrical utility Helen Ltd has contracted Landis+Gyr, a member of Japan’s Toshiba Group, to deliver a battery energy storage system to store power from two solar projects currently under construction.

The 1.2MW – 0.6MWh SCiB lithium-ion battery energy storage system (BESS) will be located in the Helsinki district of Kalasatama, and situated next to the utility’s 340kWp Suvilahti solar power plant. The energy storage system will be made up of 15 000 Li-on batteries and is reported to have over 10 000 charge-discharge cycles.

The €2m storage facility will store solar energy from the completed 340kWp plant in Suvilahti and the 850kWp plant, currently under construction in Kivikko.

According to PV Magazine, Juha Karppinen, development manager, ESS, smart grids & e-mobility said that the energy storage system will “provide frequency regulation, reactive power compensation, peak shaving and renewable energy shifting.”

Flexible RE supply 

The facility to be commissioned in 2016, will be assembled in Italy and will test the potential of megawatt-scale electricity storage in enabling flexible energy supply. Karppinen explained that the “SCiB technology provides [a] much higher cycle life than other available Li-ion technologies, which allows us more flexibility in operating the BESS.”

The energy storage facility is also envisioned to assist the development of smart grids in Finland. The electric utility said in a statement that the storage system’s primary function would be to “balance the electricity supply”

The utility added: “The benefits of this battery-operated electricity storage facility are its instant start-up and easy controls.”

Juha Karppinen noted that the success of the Suvilahti BESS (battery energy storage system) would determine the future of additional smart stoirage facilities.

“Future plans are dependent on the experiences we gain from this pilot,” he said. “The project’s greatest innovation is in the way the facility will be operated and controlled. We will study and test when it is worth charging and discharging the battery and who is prepared to pay for is at any given time and according to which logic.”
