BESS Control System (NK-EMS)

Project Summary

Implemented a test connected to the actual BESS.

Measurement of operation confirmation based on FFR test specification, communication response time / response time of power storage system.

Test result

Confirm the normality of communication between the BESS site controller and NK-EMS.

Performing the test based on FFR test the National Grid. Confirm the normality of the following items.

· Speed of delivering the response

· Proportionality of the response

· Sustainability of the response

Request response time (within 10 seconds) of FFR fully satisfied. We got the possibility to respond to EFR request response time (within 1 second).

NK-EMS successfully tested with a 4MWh BESS (partly owned by NK)

Development of a BESS in Belgium (25MWh)

Ruien Energy Storage NV (RES) is a joint venture between NK and the Belgium company Yuso.

RES is currently developing a Battery-based Energy Storage System (BESS) in Ruien (East Flanders, Belgium).

The BESS aims to deliver ancillary services to European grid operators (TSOs) as well as energy services to local businesses at the site of the former 800MW coal-fired power plant currently under post-decommissioning redevelopment.

The BESS commissioning is expected for early 2020. The capacity of the energy storage installation will be 25 MW with the option to enlarge its size later.
