Rolls-Royce Power Systems and Sunly have struck a deal, paving the way for the deployment of four battery storage systems in Latvia. This partnership promises to bolster energy innovation and sustainability in the region, marking a pivotal step towards a greener future, supporting the integration of renewables in the Baltic region.
Rolls-Royce Power Systems and Sunly have entered into a prominent partnership, formalised through contracts to develop four extensive battery storage systems across Latvia.
Collectively, these systems will boast an impressive capacity of 490 megawatt-hour (MWh). The first of these innovative hybrid energy parks, featuring cutting-edge motor and turbine union (mtu) EnergyPacks paired with solar panels, is scheduled to commence operations in Valmiera, Northern Latvia, in 2027.
mtu opetates as the product and solution brand under the Rolls-Royce Power Systems division and is the premier brand name for Rolls-Royce’s heavy-duty diesel and gas engines, hybrid systems, and emergency power supply units.
Furthermore, this initiative marks a crucial step towards enhancing the country’s renewable energy infrastructure and addressing the growing demand for sustainable energy solutions.
ENHANCING RENEWABLE ENERGY STORAGE
The agreement between the two companies was announced at the inauguration of Sunly’s new solar park in Valmiera, one of the first hybrid energy parks in Latvia.
The mtu EnergyPack in Valmiera is set to become operational in Q1 of 2027, with the other three sites following later that same year. Rolls-Royce has also secured additional contracts in Latvia and Lithuania, positioning itself as the leading supplier of battery storage systems in the Baltic states.
“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. We have to meet strict cybersecurity requirements. It was therefore crucial for us to find a European partner that has already demonstrated its expertise in Latvia.”
Rolls-Royce provides an all-encompassing solution from one centralised source, leveraging its dependable mtu EnergyPack alongside the advanced mtu EnergetIQ software platform.
This innovative software meticulously manages the intricate processes of energy storage and release to maintain grid stability. It seamlessly integrates renewable energy sources, optimises their contribution, and intelligently balances energy supply and demand to ensure a reliable and efficient power system.
“Our strength lies in providing integrated, high-performance battery energy storage systems. 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. 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.”
Andreas Görtz, President of the Mobile & Sustainable Business Unit, Rolls-Royce Power Systems
A MAJOR INITIATIVE AND STRATEGIC COLLABORATION
The contract was signed by Toms Naburgs, Managing Director of Sunly Latvia; Abhinav Bhargava, Senior Manager of Sales at Rolls-Royce Power Systems; Alexa Heinrich, Vice President of Finance for Sustainable Power Solutions at Rolls-Royce Power Systems; and Priit Lepasepp, CEO and co-founder of Sunly.
As the largest supplier in the Baltic states, Rolls-Royce has signed a memorandum of understanding (MoU) with Sunly to strengthen its partnership in Estonia, focusing on a 300 MWh project in Risti, Estonia.
To date, Rolls-Royce Power Systems has provided mtu battery storage solutions, successfully delivering over 200 projects worldwide.
Once the current projects in the Baltic states are completed, the total capacity will exceed 1,500 MWh, solidifying Rolls-Royce as the leading provider of battery storage technology in the region and, indeed, the dynamic market.
As a testament to its capabilities, Rolls-Royce has developed a large-scale battery storage system, which has been operational since 2025 for the Latvian transmission system operator, Augstsprieguma tīkls (AST).
Additionally, the company has secured contracts in Lithuania, further solidifying its presence and expertise in the region’s energy landscape and showcasing its commitment to innovative energy solutions, thereby taking a significant step forward.
