The plant will comprise a Wärtsilä BioPower 5 unit using wood residue from various sources as fuel. It will deliver hot water to the district heating network of Halmstad, a city of 88,000 inhabitants. Some of the hot water will also be used by local industry. The electricity produced will be exported to the Swedish national grid.

This is the fourth CHP installation contracted in Sweden using Wärtsilä BioPower’s BP5 plant concept, says the company. The others are in Trollhättan, Mark and Motala.

Renewable energy, combined with efficiencies from the ‘smart use’ of energy including CHP, can deliver half of the world’s energy needs by 2050, according a comprehensive new plan for future sustainable energy provision — Energy [R]evolution: A Sustainable World Energy Outlook — produced by the European Renewable Energy Council (EREC) and Greenpeace International.
