Ameresco commences execution of $5.2m energy savings contract for Austin Energy

CTBR Staff Writer Published 10 January 2013

North American renewable energy company Ameresco has commenced execution of the $5.2m Energy Savings Performance Contract (ESPC) at Austin Energy’s domain district cooling plant.

The EPSC project includes installation of a new chilled water storage system to reduce the plant's peak electricity usage by shifting the chilled water load and associated electric consumption from on-peak to off-peak hours.

Commenting on the initiative Ameresco vice president Bob Georgeoff remarked the new installations will improve the electric load profile of the facility while adding to its commitment to energy conservation.

"Under the ESPC model, Ameresco coordinates the upfront project costs and the City repays that investment with their savings over time. This model enables the City to benefit from budget-neutral upgrades by guaranteeing a minimum level of savings over the term of the contract," added Georgeoff.

The upgraded system for Austin Energy will comprise a 2.4 million (gallon) concrete thermal energy storage (TES) tank with system circulation maintained by three 200hp horizontal splitcase pumps.
