World : Wartsila delivers first engine-plus-storage hybrid plant

Finnish technology group Wartsila has delivered its first engine-plus-storage hybrid project.

The installation in Budapest, Hungary, also marks Wartsila’s first EPC energy storage project in Europe.

The storage project was delivered to Sinergy Kft, a subsidiary of ALTEO Group, a Hungarian energy service provider and trading company. An existing plant, running on three Wartsila W34SG engines, was optimised with an energy storage solution that also incorporates GEMS, an energy management system from Greensmith Energy, a US company acquired by Wartsila last year.

With the new plant, ALTEO expects to participate in the electricity market by providing frequency and secondary regulation to the national grid operating in virtual power plant mode. 

“The integration of the energy storage system is a huge step in ALTEO’s virtual power plant development and we strongly believe that this technology has opened us new opportunities to successfully respond to upcoming challenges” said Peter Luczay of ALTEO.

Greensmith Energy’s GEMS system analyses changes in market conditions and rate structures, which Wartsila said “future-proofs energy storage investments for both power developers and regulated utilities”.
