At the core of the acquisition is the jHub platform, an advanced system for the remote monitoring, control and optimisation of renewable energy and storage portfolios. Developed exclusively by Joule, it enables real-time monitoring of unit operations, more accurate production forecasting and the remote implementation of curtailment commands, as well as advanced digital services for producers through an integrated customer portal.
Greek energy group Metlen: “Italy is a core market for us”
The acquisition materially enhances METLEN's capabilities in the management and commercial optimisation of renewable energy and storage portfolios, as well as the company's aggregator business, one of the largest and most dynamic in the Greek market. The portfolio currently under management comprises approximately 1,450 renewable energy units with a total installed capacity of 3 GW, covering all major renewable technologies. The first two energy storage units, with a combined capacity of 378 MW, were also recently added to the portfolio.
Optimising energy portfolio performance
METLEN's aggregator business has also established a presence in other European electricity markets, providing producer representation services in Italy and Romania, and is in the process of expanding into Bulgaria. Curtailment and periods of negative pricing have made real-time portfolio monitoring increasingly important for renewable operators. With jHub now integrated, METLEN manages this function in-house rather than relying on external providers, giving it more direct control over how its renewable and storage assets are operated.
Giannis Giannakopoulos: “Portfolio and aggregator management is essential”
The platform also creates significant opportunities for new digital energy services, including advanced applications for storage system management, solutions for dispatchable renewable units and the commercial management of hybrid portfolios combining renewables and storage. (hcn)
