UK-based InterGen has achieved commercial operation at its 300MW natural gas-fired Spalding Energy Expansion project in Spalding, Lincolnshire.

Construction of the £100m project began in March 2018 and was carried out in partnership with Siemens, Atlantic Projects and Darke Engineering.

The Spalding Energy Expansion project consists of one Siemens F-class gas turbine in open-cycle configuration, creating a flexible peaking plant, which will provide back-up for renewable sources of generation such as wind and solar.

During the T-4 December 2016 capacity auction, the Spalding Energy Expansion project secured a 15-year capacity agreement.

It is also the first and only large-scale thermal project to secure limited recourse financing and has been built based on a capacity market award.

InterGen CEO Jim Lightfoot said: “We are delighted that the Spalding Energy Expansion project has achieved commercial operations safely, ahead of schedule and within budget.

“This plant will play an important role in providing essential power and system services during periods of peak demand.

“I am very pleased to be joining InterGen at an exciting time for the company and the sector. We are looking forward to delivering more projects that will help ensure reliable electricity supply for the UK as we transition towards a net zero economy.”

Jointly owned by China Huaneng Group/Guangdong Energy Group and Sev.en Energy, InterGen has six power plants in operation in the UK and Australia with a total generation capacity of 4,630MW.

Recently, Sev.en Energy acquired a 50% stake in InterGen from Ontario Teachers’ Pension Plan.

The existing Spalding Power station in Lincolnshire is a combined cycle gas turbine that is capable of generating up to 950MW. The plant has been operational since 2004 and is owned and operated by InterGen.

The new 300MW open-cycle station is located on land adjacent to the existing power station.
