Energy Services Acquisition Program (ESAP) – Modernization Project

The Energy Services Acquisition Program (ESAP) is modernizing the District Energy System (DES) which provides heating services to over 80 buildings and cooling services to 67 buildings in the National Capital Region (>1.6M m2 of floor space), accommodating 55,000+ occupants. The creation of a thermal grid will be able to distribute hot and cold water as energy sources and will include not only delivering energy but also receiving energy from other plants, buildings and waste heat sources.
