Rolls Royce signs 490 MWh Latvia BESS deal as Sunly cites cybersecurity rules

Rolls-Royce Power Systems will supply Baltics developer Sunly with 490 MWh of energy storage capacity across four utility-scale BESS projects in Latvia.

The contract will see Rolls-Royce deploy its mtu EnergyPack containerized BESS, as well as its battery management software platform EnergetIQ. The first hybrid energy park, featuring mtu EnergyPacks and solar panels is set to be commissioned in Valmiera in 2027.

Sunly CEO Priit Lepasepp explained that sourcing BESS from a European supplier was vital for the business.

“We need to meet strict cybersecurity requirements,” Lepasepp said. “It was therefore crucial for us to find a European partner who has already demonstrated expertise in Latvia.”

A Sunly representative confirmed to ESS News that this meant compliance with the European Union’s NIS2 Directive on securing network and information systems.

Rolls-Royce and Sunly have also signed a memorandum of understanding to extend their partnership in Estonia with a 300 MWh project in Risti.

The Baltic states have become a core market for Rollys-Royce Power Systems, with the BESS supplier on course to have more than 1.5 GWh of energy storage deployed in the region once current projects are complete.

Andreas Görtz, president mobile and sustainable business unit at Rolls-Royce Power Systems, said that offering partners a single point of contact allowed the company to reduce risk, complexity, and ensure profitable performance.

“Together with Sunly, we are supplying large-scale battery storage systems that will play a crucial role in strengthening grid stability and energy security in the Baltics,” said Görtz.
