Rolls-Royce and Voltaria to build a 43 MW large-scale battery storage facility in Scotland
mtu EnergyPack to support Scottish power grid and Clean Power 2030 Action Plan from 2027 The battery storage facility will have a capacity of 86 MWh and an output of 43 MW Rolls-Royce provides turnkey solution and long-term service More than 200 mtu battery storage systems in use worldwide
Rolls-Royce has begun construction on an Engineering, Procurement, and Construction EPC contract from leading battery energy storage platform Voltaria Helios Energy Storage to supply a large-scale battery energy storage facility in Falkirk, Scotland. This is the first large battery energy storage project by Rolls-Royce in the UK and will help stabilize the grid and support the UK’s Clean Power 2030 Action Plan.
The mtu EnergyPack, with a capacity of 86 MWh and an output of 43 MW – which is equivalent to the demand of around ten thousand homes or a large industrial site – will connect to the grid in 2026 and come online in 2027. It will store electrical energy during periods of high renewable energy production and feed it back into the grid during peak demand. The battery storage will facilitate additional renewable generation by avoiding uneconomical turn-down of wind generation. Rolls-Royce will maintain the system for 15 years.
The UK is considered Europe’s most mature market for battery energy storage systems, and it continues to grow rapidly. With its Clean Power 2030 Action Plan, the UK has set a target of providing 27 gigawatts (GW) of battery storage capacity by 2030, primarily for grid-connected applications to support carbon-free electricity supply. This capacity will help balance supply and demand, maximize electricity generation from renewable sources by reducing the requirement for expensive curtailment of renewable generation, and reduce dependence on fossil fuels.
Nigel Jefferson, CEO at Voltaria, said:
The Bankside project in Falkirk is the first of many battery energy storage sites Voltaria intends to deliver and operate.
”Rolls-Royce were selected because we were impressed by their commercial and technical offering, as well as their technical advice and engagement in the run-up to the decision, and their 15-year full-wrap long-term service agreement. Rolls-Royce and the CATL battery solution are market leaders, and both stand for quality, so our expectations for the delivery and operation of this project are high. Rolls-Royce has also leveraged the Scottish supply chain, which is great to see.”
Andreas Görtz, President Business Unit Mobile & Sustainable at Rolls-Royce Power Systems, said:
As a European turnkey integrator, we foster the energy transition by delivering storage solutions – from system design and EPC delivery to intelligent control and lifecycle support.
”Our collaboration with Voltaria draws on all the experience we have gained in over 200 battery projects worldwide.”
Voltaria Helios Energy Storage is a joint venture between Helios Energy Investments, a group of private equity funds focused on energy transition investments, and Voltaria (which is owned by Renewables Infrastructure Capital).

aw firm Foley & Lardner LLP released today its 2026 Data Center Development Report, focusing on the growth and challenges in the data center boom that aims to sustain the growth in AI and LLM usage.
A major focus was on energy, with 54% of respondents citing “energy availability and redundancy” as the single greatest obstacle to successful data center development between now and 2030.
Join us on April 22 for the 3rd SunRise Arabia Clean Energy Conference in Riyadh. The event will spotlight how solar and energy storage solutions are driving sustainable and reliable infrastructure, with a particular focus on powering the country’s rapidly growing data center sector. In terms of the right energy mix for data centers, 55% of respondents agreeing that the ideal energy mix to meet the growing power demand of data centers is largely renewables (41%), followed by natural gas (17%), nuclear (16%), and BESS (14%). Nearly half (48%) of industry participants named advances in energy efficiency (which often includes storage optimization) as the greatest opportunity for development through the end of the decade, and nearly three in four respondents (74%) said advanced energy storage systems like batteries, hybrid solutions, and microgrids are the best way to ensure energy resilience. Only 14% of developers are actually pursuing modular and small modular nuclear reactors as a viable energy opportunity. Intriguingly, 63% anticipate a “strategic correction” in the market by 2030, driven by the intense competition for power, with one unnamed banking executive in the report saying, “Once power runs out in 2027 or 2028, that’s where we think deal flow will start to slow down.” 105 U.S.-based respondents were qualified to participate in the survey, including those who had direct experience in data center development, energy procurement, technology delivery, or operations within the past 24 months. Energy analyst firm Wood Mackenzie identified data centers as one of the five trends to look for in 2026 for global energy storage, and within the past week, a battery storage project decided to give up a grid-connection to a data center and re-tool the batteries, earning revenue without being connected. What they said: Daniel Farris, partner and co-lead of Foley’s data center and digital infrastructure team: “There is a Gold Rush mentality right now around securing power. That’s a big part of why people feel there’s a bubble,” said “There’s going to a period in the next two to three years where power at necessary levels is going to be really hard to come by.” Rachel Conrad, senior counsel and co-lead of Foley’s data center and digital infrastructure team: “Over the next five to 10 years, power providers will need to either grow capacity or increase efficiency to meet the demand fueled by data centers.” Want to learn more about matching renewables with data center demand?
Scientists at CeNS in Bengaluru have created a photo-rechargeable supercapacitor, known as a photo-capacitor, which simultaneously captures and stores solar energy, eliminating the need for separate solar panels and batteries. This innovative device enhances efficiency and compactness, paving the way for advanced, self-sustaining power systems in portable electronics and renewable energy use.

In Detail : Telangana is preparing for a significant shift in its energy landscape as electricity demand in the state is expected to cross 100,000 MW by 2047. Rapid urbanization, industrial expansion, digital infrastructure growth, and rising living standards are driving a sharp increase in power consumption. To meet this demand sustainably, the state has outlined a long-term strategy centered on renewable energy and energy storage.
A key pillar of Telangana’s plan is achieving a 50% green power mix in its overall electricity portfolio. This involves scaling up solar, wind, and other renewable sources to reduce dependence on fossil fuels and minimize carbon emissions. The transition is aligned with national clean energy goals and reflects Telangana’s ambition to position itself as a leader in sustainable development.
Solar energy is expected to play a dominant role in this transition due to Telangana’s high solar potential and availability of land for large-scale projects. Rooftop solar, utility-scale solar parks, and solar integration in industrial and commercial zones are being promoted to decentralize generation and reduce transmission losses. Wind and hybrid renewable projects are also expected to complement solar generation.
As renewable energy penetration increases, grid stability becomes a critical challenge. Intermittent power generation from solar and wind creates variability that must be managed effectively. To address this, Telangana is planning significant investments in battery energy storage systems to balance supply and demand, ensure reliability, and support round-the-clock power availability.
Battery storage is being positioned as a strategic enabler of the green transition. Large-scale storage systems will allow excess renewable energy generated during peak periods to be stored and dispatched during high-demand or low-generation hours. This not only improves grid resilience but also reduces curtailment of renewable power and enhances overall system efficiency.
Grid modernization is another central component of the state’s energy roadmap. Upgrading transmission infrastructure, deploying smart grid technologies, and integrating digital monitoring systems will enable real-time demand management and efficient power distribution. These measures are essential for accommodating large volumes of distributed renewable energy and storage assets.
The expansion of green power and storage is also expected to have strong economic implications. It will attract private investment, create employment opportunities, and stimulate the growth of clean energy industries within the state. Manufacturing of solar equipment, batteries, and related technologies could emerge as new industrial clusters.
From a policy perspective, Telangana’s strategy requires coordinated planning between government agencies, utilities, regulators, and private developers. Supportive policies, long-term power purchase agreements, financial incentives, and regulatory reforms will be necessary to accelerate renewable deployment and make storage systems commercially viable.
Overall, Telangana’s vision of achieving a 50% green power mix with large-scale battery storage represents a forward-looking approach to energy planning. By proactively addressing future demand growth and sustainability challenges, the state is building a resilient, low-carbon power system that supports economic growth while contributing to national and global climate goals.
