Colchester Amphora Energy Ltd was set up to act as ESCO for the Colchester Northern Gateway Heat Network which is being jointly developed by Colchester Borough Council (CBC) and CAEL (wholly owned by CBC).

The primary heat source will be an 800kW open loop water-source heat pump utilising five 135 metre boreholes into the confined chalk aquifer75 metres below ground level. There is over 550m separation between the two abstraction and three re-injection boreholes making one of the largest separations in the UK.

This is a significant flagship project, both for Colchester and the UK. In 2017, it was 1 of only 9 operations in the UK to gain funding from the Department for Business, Enterprise & Industrial Strategy (BEIS) Heat Network Investment Project.

The project will deliver approximately 5.5 GWh of low carbon heat per year when the Northern Gateway development is complete, this equates to about 80% of the total heat required. This technology is seen as potentially an important part of reducing carbon for the heating of 350 homes, 300 retirement apartments, 30,000 square meters of offices and 10,000 square meters of healthcare facilities.
