The Greek energy group is expanding its M RESET division with grid-scale storage projects in three European markets. Recent milestones include a 129 MW project in the UK, a 25 MW asset in Italy and Greece's largest standalone battery at 330 MW.
The acquisition of the digital platform developer brings jHub in-house for the Greek energy group, giving it a platform for real-time monitoring, forecasting and curtailment across its 3 GW renewable and storage portfolio.
METLEN's integrated utility chief explains how the group fuses generation, storage, trading and supply into one platform, underpinning decarbonisation, customer affordability and industrial resilience across more than 40 markets.
With a 3 GW pipeline of solar and battery projects, Metlen is strengthening its position in Italy through new storage projects, tolling agreements and partnerships with industrial energy consumers.
Metlen and Tsakos Group will jointly invest in one of Greece’s largest hybrid plants, combining large-scale solar generation with 375 MWh of battery storage, scheduled for completion in early 2028.
The partnership grants Acciaieria Arvedi access to the Energy Release 2.0 framework, with roughly 2.4 TWh of electricity to be delivered from a 170 MW solar portfolio.
A new joint venture from Metlen and Karatzis will deliver a €170 million utility-scale battery system in Thessaly, with completion targeted for Q2 2026.
Metlen has signed a 10-year Power Purchase Agreement (PPA) with Engie to supply solar-generated electricity from six sites across the UK.
