Portland Gas is a joint venture between InfraStrata plc and eCORP.

The Old Engine Shed due to be transformed into an interpretation centre will be the highlight of the Portland Gas Trust's work on Portland.

At a projected 1,000 million cubic metres (“mcm”) or 35 billion cubic feet (“bcf”) of working gas, the gas storage facility would be the largest of the publically announced onshore gas storage facilities in the UK. Planning permission was granted by Dorset County Council in May 2008 and Pipeline Construction Authorisation was granted by the BERR (now known as the Department of Energy and Climate Change) in July 2008. The gas storage facility is designed to inject or withdraw gas at 20mcm per day. The current estimate of total development cost for the project is £456m. The project will use brine compensation technology and will not require cushion gas.

Portland Gas believes in supporting local communities with projects that increase public understanding of geology and benefit education and the environment. In Dorset the Company set up the Portland Gas Trust, based on the Isle of Portland, to work with projects across the county.
