Glenwood, an owner and builder of luxury rental properties in Manhattan, is deploying 1 MW of distributed energy storage systems in nine buildings in its real estate portfolio. Construction will begin this month on systems in the first properties, with commissioning completed in the first half of 2015. The energy storage systems will be operational for the summer peak load season and will support the Indian Point Demand Management Program that Con Edison and NYSERDA are offering to commercial customers.
Glenwood installed its first energy storage system two years ago at its Barclay Tower property. That 225 kW system, developed by Demand Energy, has been operating successfully, and based on the compelling economics of the system, Glenwood is moving forward with more energy storage.
Glenwood has contracted with EnerSys, a provider of industrial battery solutions, and Demand Energy to deliver, install and operate an aggregated 1 MW of energy storage across the nine Glenwood properties.
According to Doug Staker, co-founder and VP of global sales for Demand Energy, Glenwood has stated its intention to deploy energy storage systems across its entire portfolio. This announces the first phase of that effort. One of the buildings has a larger load and requires two systems, thus the announcement of ten systems or 1 MW of aggregated behind-the-meter energy storage systems.
Staker says each of the systems is installed inside of each of the buildings. These systems are networked together through Demand Energy’s cloud-based energy storage platform called Joule.System. Each system can run individually and respond to load at each building. If there is a demand response event, all of the systems can be coordinated to stop their individual activities and function as a single resource for grid support. The systems receive daily files from the transitive energy market in New York City. Demand Energy integrates the day ahead hourly pricing information to make decisions on charging and discharging and can receive and respond to utility operator’s signals for demand response or other grid support.
Demand Energy says the deployment represents the first example of a networked distributed energy storage portfolio in NYC that is capable of managing individual building loads in real-time or responding as an aggregated asset to a critical power event called by Con Edison or NYISO.
Glenwood will participate in the Indian Point Demand Management program jointly released by Con Edison and NYSERDA. Each storage system will deliver four hours of load reduction (400 kWh) between 2 pm to 6 pm Monday through Friday, June through September. They will be dedicated for this load reduction program for ten years. In the off-peak season, they will go back to daily demand reduction for the loads in each building and will respond to any critical power events that may occur during the winter operations.
