ESCO in a box is a concept being developed with government support with the aim of improving takeup of energy-saving measures among small and medium enterprises.
In essence, the project is designed to enable respected local community organisations (for example) to set up as providers of energy-saving services to the SMEs in their area, by equipping them with a complete package of technical, analytical, legal and financial components.
The originators of the idea, EnergyPro Ltd, have produced an overview of the scheme and I interviewed their managing partner, Steven Fawkes, about it on 15 April. The recording will be available until 14 May at http://bit.ly/ESCObox (apologies that the recording is missing the first couple of minutes).
