Rolls-Royce Power Systems (LSE:RR.) has entered into agreements with Baltic renewable energy developer Sunly to build four large-scale battery energy storage facilities in Latvia, adding a combined 490MWh of storage capacity to support grid resilience and energy security in the region.
The announcement was made during the inauguration of Sunly’s new solar park in Valmiera, one of Latvia’s earliest hybrid renewable energy developments.
First Project Scheduled for 2027 Launch
Construction will begin with a battery storage facility in Valmiera, which is expected to enter service during the first quarter of 2027.
The remaining three installations are scheduled to become operational later that year, expanding Latvia’s energy storage infrastructure as renewable generation continues to grow.
Together, the projects are intended to improve grid reliability by helping balance fluctuations in electricity supply and demand.
Rolls-Royce to Deliver Turnkey Storage Solution
Under the agreement, Rolls-Royce will provide a fully integrated battery storage package built around its mtu EnergyPack technology and the mtu EnergetIQ energy management software platform.
The solution is designed to optimize the storage and release of electricity, helping grid operators maintain stability while supporting the integration of renewable power sources.
Rolls-Royce will also serve as the project’s general contractor, overseeing design, procurement and construction activities from start to finish.
Focus on Grid Stability and Energy Security
Andreas Görtz, president of the mobile and sustainable solutions business unit at Rolls-Royce Power Systems, emphasized the benefits of the company’s turnkey approach.
“As a general contractor, we offer our customers a single point of contact, which helps them reduce risks and complexity, ensure profitable performance and maximise long-term asset value.”
He added that the collaboration would contribute to strengthening regional energy infrastructure.
“Together with Sunly, we are delivering large-scale battery storage systems that will play a crucial role in strengthening grid stability and energy security in the Baltic region.”
Sunly Highlights Reliability and Cybersecurity Requirements
Sunly selected Rolls-Royce following previous cooperation in the Baltic market and the company’s ability to satisfy both technical and cybersecurity standards.
The renewable energy developer views battery storage as a critical component in improving the reliability of renewable energy generation.
Sunly Chief Executive Officer Priit Lepasepp said: “Our aim is to build an energy system that serves people – not just when the sun is shining. By combining solar power generation with battery storage, we can supply energy when it is needed. This makes renewable energy more reliable and less dependent on the weather.”
