Plan for $100m network of pipes

Christchurch's new energy agency will be driving a proposal to build a $100 million network of heating and cooling pipes around the central city.

An energy-efficient central plant burning wood chips would generate hot and cool water to pipe to commercial and residential properties.

The proposed district energy system (DES) would provide space heating, domestic water heating and air conditioning, meaning individual buildings would no longer need to run their own boilers, chillers or air conditioners.

The system is one of the proposals in the draft central-city plan and would involve a combined heat and power plant and an about 10-kilometre network of pipes.

The Christchurch Agency for Energy, launched yesterday, will investigate options for improving the city's use of energy, increasing the proportion of renewable energy used and providing accurate energy supply and consumption figures.
