Stag Energy is an independent UK based company providing expertise and management services to innovative energy development projects in the rapidly evolving electricity and gas sectors.


The company’s primary business focus lies with gas-fired power generation, standby electricity generation, underground gas storage and associated infrastructure. As the structure of energy markets evolve to incorporate an increasing proportion of intermittent renewable generation, Stag Energy is also assessing the potential to utilise gas storage technology for energy storage, and fossil fuel power generation schemes, including carbon neutral power generation plants to enable electricity supply to follow demand.


Stag Energy works with partner companies wishing to invest in the UK and European energy markets, and who wish to ensure assets are structured to accommodate financing and the management of commercial risk.

Stag Energy is developing projects in the UK, in the following areas:


Power Generation: Building on extensive experience in this sector, Stag Energy is managing the development of new open cycle gas fired peaking plant and emergency standby generation prospects at a number of sites in England and Wales.


Gas Storage: Facilities in recognition of the increasing demand for energy price insurance and security of supply.


Alternative Energy: With knowledge and experience in power generation, transmission and underground storage, Stag Energy is progressing forward initiatives to assist in modulating energy supply from intermittent renewable resources


Transmission Systems: Stag Energy brings project development expertise to ensure a secure infrastructure is available to convey a produced energy to the point of use


Key Initiatives



Watt Power is an energy infrastructure development and operating company. Its purpose is to develop and own energy projects related to power generation. Development activities include the sourcing of new energy prospects, securing of consents and property rights, negotiation of commercial and financial arrangements and the preparation for construction and operations.


Watt Power has been seeking to develop a portfolio of small, flexible power projects to support the security of electricity supply in England and Wales since 2012.  The principle focus of these efforts has centred on the development of two 300MW gas-fired generation projects in wholly-owned subsidiary companies Progress Power and Hirwaun Power.  These projects participated in the 2015 Capacity Market Auction but were unsuccessful in securing contracts.


Watt Power’s subsidiary company, Prime Energy, has focused on small-scale distributed generation projects.  Seven Prime Energy projects were successful in the 2015 Capacity Market Auction, and subject to their raising construction finance, are targeted to be built in time to meet their Capacity Mechanism commitment in 2019, at the latest.  Each 20 MW project will provide short-run back-up generation to the Grid, at times when electricity demand is at its highest – normally during winter weekday evenings.





Gateway Storage Company Ltd has secured the necessary permits, consents and land agreements to build an underground natural gas storage facility in the East Irish Sea, approximately 25 km (15 miles) offshore, south west of Barrow-in-Furness. Subsurface analysis and engineering design work have been concluded in support of a storage facility developed in bedded salt approximately 1,000m below the seabed. Gas would be delivered, stored and then returned the UK´s national transmission system to provide enhanced security of UK gas supplies and increase consumer protection from disruptions and price spikes in the international gas market.


Gateway is one of the most mature gas storage development prospects and is well positioned to respond to demand for UK gas price insurance and gas security, plus future demand for underground energy storage using Synthetic Natural Gas.
