Chelsea Piers CT Reduces its Peak-Hour Electricity Demand by 40% with Clean Peak Energy, Setting Potential $25,000 Savings

STAMFORD, CT — Clean Peak Energy Group announced it successfully curtailed the energy demand at a large sports and entertainment venue in Connecticut by 512 kW during a potential system peak-hour with the deployment of its patented thermal-energy storage technology June 7-8, 2021. The thermal-energy protocols resulted in a reduction of hundreds of kW for the facility during the predicted peak system hour without exceeding temperature designs. The savings for the facility for the subsequent year installed capacity would be over $25,000 if the hour is the annual system peak hour in New England.

The deployment, during a period of high temperatures in the Northeast in early June, 2021, enabled the 400,000 square-foot Chelsea Piers Connecticut facility to drastically decrease its peak-hour power demand while recording an increase of internal building surface temperature of less than 1 degree.

Clean Peak Energy dramatically reduced the peak-hour electricity demand at the facility though its patented thermal-energy storage technology – which relies solely on the building’s physical mass for thermal-energy storage and requires no additional in energy-storage equipment.

During the pre-determined peak-demand period, between 4:00 PM and 7:00 PM, Clean Peak’s analysis enabled the facility to power down the air conditioning chillers as well as the ice-rink chillers. The result – For the day’s peak-demand hour, from 5:00 PM to 6:00 PM, the facility curtailed its electricity demand by nearly 40%, saving 512 kW in demand, according to meter data from Eversource (see chart 1) – while experiencing an increase in the building’s internal temperature of less than 1 degree.

On a same-day comparison basis over the peak-demand period for three of the past four years, the facility’s demand was 1391 kW on Aug. 18, 2018 and again on July 30, 2019, according to Eversource. The facility’s demand during the peak-demand period in 2017 was 1768 kW. This year, during the Clean Peak deployment on June 8, 2021, demand was curtailed to just 892 kW – a reduction of nearly 500 kW from 2018 and 2019, and 906 kW lower than 2017 (Chart 2).

Clean Peak Energy’s deployment of its technology at Chelsea Piers Connecticut was the first of a series of planned initial deployments in the region, as a means of demonstrating the substantial role its technology is poised to play in energy conservation moving forward. In addition to slashing the cost of electricity for large commercial buildings, Clean Peak Energy’s technology results in substantial reductions in carbon emissions by shifting energy demand to off-peak hours, when power is generated from the most efficient, cleanest-burning sources.
