Energy storage projects in Con Edison Demand Management Program first to reach Measurement and Verification testing stage
Demand Energy, a leader in intelligent energy storage systems, in partnership with leading battery maker EnerSys, today announced completion of the first five storage projects to be enrolled in Con Edison’s Demand Management Program (DMP). One of the five 100 kW/400 kWh behind-the-meter energy storage systems has already passed the Measurement and Verification (M&V) testing stage. Testing is under way with the other four systems, which are installed in separate properties across Manhattan owned by Glenwood, one of New York’s largest owners and builders of luxury rental apartments.
These aggregated systems are powered by Demand Energy’s DEN.OS™(Distributed Energy Network Optimization System), an intelligent software control platform that maximizes economic returns from behind-the-meter storage systems alone, or in combination with distributed generation resources, such as fuel cellsand solar power.
“We’ve been working during the winter season to install and interconnect the next four systems that will deliver the first of 4 MWh of distributed storage for Glenwood, leveraging four years of experience we have working with them,” said Shane Johnson, VP of Operations for Demand Energy. “Our DEN.OS can aggregate and manage a mix of energy storage assets to respond to Con Edison’s localized peak problems, enabling Glenwood to respond to the demanding requirements of the dynamic New York energy market.”
To qualify for the DMP incentive program, Demand Energy had to demonstrate that its first battery energy storage system, installed at Glenwood’s Paramount Tower property last year, could deliver the required four hours of continuous output during the afternoon hours (2:00 to 6:00 pm) for a period of four weeks. The load at Glenwood’s Paramount Tower was reduced by 100 kW continuously during the test period and system performance was validated. Once the M&V was completed, the system went into full operation. The DMP operational season lasts from June 1st until September 30th, at which time Glenwood is free to switch operating modes and begin providing demand charge reduction and other load management functions during the off-peak season.
“At Glenwood we have always believed that it is our duty to support load reduction on the grid during the critical summer power season,” said Josh London, SVP of Management for Glenwood. “With the flexibility of Demand Energy’s solution, we can participate in the summer DMP program and then use the energy storage system to reduce our demand charges during the off season. By flattening our building’s load overall, we are able to provide added stability to the local operating grid.”
The remaining four systems started M&V testing on June 1, and will be completed the first week of July. Demand Energy is in the process of installing another five systems for Glenwood this summer. When completed, Glenwood will have a total of 1 MW/4 MWh of energy storage enrolled in the DMP.
The Con Ed DMP was designed to deliver verifiable load reduction during the summer load season, and in particular help reduce stress on the distribution grid within New York City for four hours during the weekday peak hours between 2:00 and 6:00 pm. The New York grid can be strained during peak hours to a level of stress that can cause system disruption anywhere within the five boroughs. The region experiences peak loads that can vary by as much as 2 GW for short periods during the summer air conditioning season. By deploying distributed energy resources, such as the 1 MW of aggregated storage across nine of Glenwood’s buildings in Manhattan, the impact to the local grid can be minimized – and these flexible resources can provide system stability during periods of high demand.
“We are fully behind Con Ed’s efforts to improve the resilience of New York’s grid in the face of any extreme weather conditions and, importantly, the almost continual load growth that could further stress the grid,” added London. “You cannot walk even a few blocks here without seeing a tower crane at a construction site. We see the DMP as a significant step in averting grid incidents due to the everyday stresses on the infrastructure, which are magnified during events like heat waves.”
