Clean Peak Energy’s technology slashed energy demand in large commercial buildings in CT and MA this summer, setting the course for saving customers tens of thousands of dollars.
STAMFORD, CT – Clean Peak Energy Group’s patented thermal-mass energy-storage technology successfully curtailed energy demand in large commercial buildings in New England during 2021’s energy-demand peak, capping a successful first-year deployment initiative and setting the course for saving tens of thousands of dollars in electricity costs at the buildings over the next year.
During the 2021 energy system peak load period, which in New England occurred on June 29 between 5:00 pm and 6:00 pm, Clean Peak Energy’s technology enabled the operators of Chelsea Piers Stamford, a 400,000 square-foot sports facility in southern Connecticut, to reduce electricity demand by 772 kW compared to the previous pre-Covid peak load period in 2019. Clean Peak’s system enabled the facility to curtail demand during this critical period while maintaining a targeted interior temperature range, resulting in a potential savings of nearly $54,000 in electricity costs for the upcoming year.
In New England, as in many regions in the U.S., electricity costs are based in part on projected demand capacity requirements. The installed capacity, and its cost allocation to customers in New England and in New York, is calculated based on electricity customers’ demand during the one hour when electricity demand reaches its peak for the year.
By identifying this peak demand period in advance utilizing Clean Peak Energy’s thermal energy storage services and curtailing electricity use during this one-hour period, electricity customers can reduce the demand-capacity portion of their electricity supply for the next 12 months.

In Massachusetts, Clean Peak’s technology was deployed by a Fortune 100 company in one of its office buildings later in the summer as part of an agreement. The deployment was successful in slashing electricity usage on a high-demand day in late August by 45% from the same one-hour period the day before, while keeping the building’s interior temperature within a targeted comfort range. Had the test taken place on the actual ICAP peak hour in June, the company would have been positioned to reduce its 2022 electricity costs for the building by more than $45,000, based on the current ICAP calculation.
In a previous test at the facility on August 12, Clean Peak’s technology delivered similar results. When comparing the August 12 demand using Clean Peak’s system to the facility’s actual demand measured on the June 29 peak-demand period, the facility would have reduced its 2022 electricity cost by $14,481. These figures represent an improvement of more than 30% over the results previously achieved the by experienced building managers at the same locations – with no additional costs.
Clean Peak’s system, which uses the building’s mass as a means of thermal energy storage, requires no construction, permitting or equipment space. In each of these locations, the technology was deployed with no alterations to the buildings. For more information on Clean Peak’s technology, visit https://cleanpeakenergy.us/contact/.
