(now owned by Tractebel). In 1988 the privately owned Dutch company, SHV became a significant shareholder, acquiring 40% of Calor Group's equity. In 1991, a joint venture company involving Calor, SHV and Primagaz (in which SHV holds a 50% stake) had been started in both Poland and Slovakia. This was then followed by Hungary in 1992. In 1997 SHV acquired the rest of Calor's shares. In 2002 Calor opened 12 Customer Operations Centres at Grangemouth, Port Clarence, Stoney Stanton, Elland, Ellesmere Port, Coryton, Cranbrook, Saxham, Fawley, Neath, and Newbury. In December 2005 The Canvey LNG project was announced which commenced with a feasibility study into the development of a strategic LPG import and regasification facility at the existing Calor LNG terminal at Canvey Island, Essex UK. The project is led by Calor Gas and also includes LNG Japan Corporation, (Joint Venture of Sumitomo Corporation and Sojitz Corporation). Following this study Centrica has now been selected as a gas supply partner and would hold equity in the facility, together with capacity rights enabling it to deliver supplies to their British Gas customers from a range of international sources. A full scale planning application and project plan is now being developed. On 16 of February 2023 Calor announced workforce reduction of 114 positions in Commercial, Operations and Central Functions departments.

For leisure use such as caravanning and barbecuing, Calor retail butane, propane and Patio Gas (an alternative brand name for propane) cylinders, all of which come in a number of sizes.
