Toshiba advances Spain storage test

Toshiba has teamed up with Spanish utility GasNatural Fenosa (GNF) and Japan’s New Energy and Industrial Technology Development Organization (NEDO)  to regulate transmission of renewable-generated electricity via the Japanese conglomerate’s transportable lithium-ion battery energy storage system (BESS).

The five-year demonstration project started last month at the Alcalá de Henares substation in suburban Madrid. However, Toshiba and GNF plan to eventually test the transportable BESS at other sites as well.

They will evaluate the ability of the BESS to manage electricity flows at locations in which power demand tends to spike on a seasonal or temporary basis, Toshiba said in an online statement. They will also test the system’s ability to manage power and voltage fluctuations caused by renewable-energy resources.

The BESS, which boasts an output of 500kW and a capacity of 776kWh, is designed to ensure "an efficient, reliable and stable distribution network," Toshiba said.

In November, Toshiba agreed to provide a lithium-ion battery storage system for a trial project under regional Japanese utility Tohoku Electric Power to regulate and expand transmission of electricity generated by solar and wind projects.

The system will be installed at a substation in the northern Japanese city of Sendai, Miyagi prefecture, by February 2015, with 20MWh of storage capacity and maximum output of 40MW.

This past summer, power equipment manufacturer Sumitomo Electric Industries also won a contract from Japan’s Ministry of Economy, Trade and Industry (METI) to provide a similar large-scale battery, with 60MWh of storage capacity, on the northern Japanese island of Hokkaido.
