This Solution supports local governments in retrofitting existing district heating systems to make them more modern, energy efficient and cost-effective. It is applicable to old systems – from small to large – facing difficulties and which are owned, operated or regulated by the local government.
As other infrastructure, to be able to deliver expected performance levels, district energy systems need adequate operation, maintenance and replacement at the end of useful life. For funding to be available for this, a sound business model must be put in place to ensure an adequate customer base and steady revenue streams.
The key roles local governments can play in the implementation of this Solution are:
– promoting modern technologies/systems/practices such as combined heat and power generation (CHP), smart systems and improved automated control
– facilitating the use of local renewable resources and waste heat
– reviewing metering policies, tariff regulation and other policies and regulations to remove barriers and incentivize modern district energy
– contributing to a sound business model
– facilitating access to funding for needed retrofitting works.
