As the energy landscape becomes more complex, Stag Energy brings experience and understanding to the evolving landscape of energy infrastructure:

Reserve Power Generation

As the energy sector transitions to a low carbon future, the role of gas reserve power capacity and Demand Side Response (DSR) will play an increasingly important role in providing system support and balancing services.

Over that last 10 years, Stag Energy has developed and managed over 1,500MW of reserve power capacity around the UK.  Our expertise in selecting the most appropriate sites for electrical connections and straightforward planning consent has enabled swift development and the deployment of cost-effective solutions.

Transmission Systems & Stability

National Grid is overseeing a transformation of the UK electricity system as they develop the capability to manage a network with 100% renewable generation by 2025. The National Grid Pathfinder Programme is seeking to procure services to underpin System Stability and to alleviate transmission Boundary Constraints. Stag Energy is actively engaged in progressing projects to meet these services at locations around the UK.


Solar PV technology is well established in the UK and has an important role to play in the decarbonisation of the UK power system. The cost of solar PV technology has been falling, which enables solar energy schemes to proceed without public support or subsidy. A solar scheme can be enhanced by co-locating battery storage that can make the scheme more flexible and support the electricity network. Stag Energy provides a development and management capability to deliver cost-effective, high-efficiency solutions to the solar sector.


Storage is becoming a critical part of energy system development as intermittent renewables require storage of energy and system balancing to ensure a stable and reliable electricity system throughout the year.

Battery – Battery storage is establishing a growing role to provide short term storage and system balancing services, often co-located with solar or wind facilities. Stag Energy is engaged in the development of energy storage projects which can take power from the grid at times of high renewable generation and release it for use at other times. These projects may also be combined with grid stabilisation equipment.

Natural Gas & Hydrogen – for longer-term seasonal storage of energy, gas is one of the most cost-effective means of storing large volumes of energy.  Stag Energy has developed the Gateway salt cavern Gas Storage project, in association with the Lundin Group, and  completed  the necessary environmental, engineering, design and planning work to prepare the facility for construction.  The project has the potential to provide a significant energy reserve for the UK market at a time when energy production and utilisation are becoming more volatile and unpredictable.
