RWE exits Five Estuaries stake; ENGIE opens Chile battery; HELLENiQ completes Greek storage
RWE completed the sale of its 33.33% stake in the Five Estuaries offshore wind project to EDF, which will lead development on behalf of the remaining shareholders. ENGIE started commercial operation of the 142 MW/802 MWh BESS Lile battery project in Chile, a roughly $174 million installation at the Mejillones Energy Complex. HELLENiQ ENERGY finished a €50 million, 100 MW/200 MWh battery facility in Thessaloniki, Greece, using lithium iron phosphate technology.
RWE's divested Five Estuaries interest sits in the southern North Sea, covering about 128 square kilometres. Its December 2025 consent allows as many as 79 turbines with maximum tip heights of 370 metres; output could match roughly one million UK homes. RWE plans to redeploy sale proceeds into other approved offshore wind schemes.
ENGIE's Chilean BESS Lile uses 160 battery containers and 40 electrical units, discharging for about five hours and serving more than 84,000 households. It reuses substation, land and roads from a former coal unit. HELLENiQ's Thessaloniki plant uses liquid-cooled lithium iron phosphate across three stations, linked by a five-kilometre underground line and a new 33/150 kV substation.

These developments may improve grid flexibility and support coal-to-cleaner transitions, potentially benefiting households and businesses in the UK, Chile and Greece. Offshore wind and storage could reduce exposure to fuel-price swings, while communities near former thermal sites may gain new industrial activity. Outcomes for ratepayers, workers and local grids could vary with permitting, connection timing and market rules, so the projects represent potential shifts rather than guaranteed effects.
