The guidance note on energy solutions for hub DBFM projects provides information on the energy usage and price risks retained by the Authority under the standard form hub DBFM Agreement. The energy solution proposed by hubCo on a project will be a factor in the Authority's assessment of the ongoing affordability and budgeting implications of the project. The guidance note also highlights the implications of the energy solution proposed for the Authority's utilities costs and revenues, including entitlement to certain revenues such as renewables incentives. The extent to which reliance is placed on different energy sources for a particular utility will directly impact the Authority's utilities costs and revenues. The guidance note emphasizes the importance of adequate maintenance of the CHP plant to avoid reliance on back-up generators, which could result in higher utilities bills and lost incentives.
