Bridgeport – District Energy Project

The Bridgeport project seeks to create a low-temperature heating and cooling system to reduce CO2 cost-efficiency.


CHP (combined heat and power) has been identified as a critical tool to reduce CO2 cost-effectively. Currently CHP makes up about 8 percent of U.S. total generating capacity. The present installed capacity of CHP in the U.S. is about 82 GW, and the Obama administration has set an official goal of 40 GW of additional CHP capacity by 2020.

The United States relies primarily on steam heating, which can be a costly affair to operate and maintain as well as being a potential safety hazard. Located 100 km/65 miles northeast of New York City on the New York-Boston corridor, Bridgeport is a perfect model for low-temperature district heating with its 150,000 inhabitants and available surplus heat. A traditional steam system would never be feasible, but the hot water system is.

Inspired by the Copenhagen model, Bridgeport has chosen to use a similar method to create a low-temperature heating and cooling system.

CLEAN’s role

CLEAN drives the process from the conceptual phase of the project until the project is developed, upon which the city and the project partners sign the contact. Specific tasks that CLEAN provides includes:

  • • Identify, initiate and facilitate projects and partnerships
    • Develop projects together with committed companies, partners, cities and clients
    • Coordinate the internal work between partners and keep contact with the client
    • Negotiate on behalf of the partners concrete financing solutions and agreements with financial institutions

Outcome/Project status

CLEAN and a Danish consortium of companies have had dialogue with Nupower Thermal since the beginning of 2014, which resulted in bidding process for a prefeasibility study. Ramboll, one of the consortium partners, won this together with two American advisers. This work is now finished and it creates the basis for an extended feasibility study that, if it meets expectations, can lead to an EPC-M contract in 2016.

At the current stage, the Bridgeport project is in an interactive process to analyze the feasibility of construction. The Danish consortium have succeeded to enter into an agreement with NuPower, so the Danish consortium is guaranteed the project under prerequisite of the consortium’s compliance to the agreed economic framework. Implementation of the project is set for third quarter of 2016.
