Princeton Power Systems, a leading global designer and manufacturer of technology products and embedded software for energy management, micro-grid operations, and electric vehicle charging, is providing technologies at the heart of breakthrough energy storage projects that will manage electricity demand in a group of New York City buildings.
Glenwood, which builds and owns luxury rental property in Manhattan, has contracted with EnerSys and Demand Energy to install 1 megawatt of energy storage capability in multiple buildings throughout New York City. For the first time in New York, a networked energy storage portfolio behind the customer meter will be able to manage individual building real-time loads and also respond to calls to cut electric use by Consolidated Edison or the New York Independent System Operator (NYISO), which runs the state's grid. This aggregation of individual energy storage systems will solve the increasing need for peak load reduction while at the same time increasing individual building and overall grid resiliency.
The Demand Energy designed storage systems will use Princeton Power Systems' GTIB-100 bi-directional converters, which were designed for advanced batteries, solar, on-grid and off-grid applications. The converters will link the batteries to the grid and manage power flow as an integral part of the Power Conversion System (PCS) architected by Demand Energy.
The deployment of these systems by the EnerSys and Demand Energy team are part of New York's groundbreaking effort to develop a market based distribution grid system that enables the integration of a variety of distributed resources including renewable energy and energy storage, allowing customers to produce their own power and can better withstand major storms. Called Reforming the Energy Vision, or REV, the initiative is being watched by other states and countries that may adopt similar policies.
The deployment of these networked energy storage systems for Glenwood signals a growing role for energy storage in behind-the-meter (BTM) applications for commercial/industrial customers, according to Princeton Power Systems, which designs and makes technology and software for energy management, microgrid operations and electric vehicle charging.
"Glenwood's selection of the Demand Energy system is an exciting development for the New York market," said Darren Hammell, co-founder and Chief Strategy Officer at Princeton Power Systems. "We expect the market for energy storage in the city to grow rapidly, providing benefits to businesses, residents and grid resiliency."
New York City is viewed as a strong market for energy storage and on-site renewable energy because of its high demand for power, lack of available and affordable real estate for central power plants, historic transmission constraints and environmental goals.
The 100kW/400kWh Demand Energy storage system is New York's first fully approved behind the meter system that delivers the four hours of stored energy, required to meet the NYSERDA/ConEd Demand Management program. In addition to Princeton Power converters, Demand Energy's storage systems will use advanced lead-acid (VRLA) batteries from EnerSys. "At EnerSys, we are providing a full range of integrated support services and the deep technical expertise needed to support the deployment of these systems," said Ed Stein, manager of business development for Enersys. "We think Glenwood's system can be a model for other projects in New York City, and Princeton Power is a key technology provider for us."
"Princeton Power's converter exceeded the demanding requirements we needed for a bi-directional converter that would be at the heart of our comprehensive Power Conversion System (PCS)," said Gregg Patterson, President and CEO of Demand Energy. "With all the required certifications for behind-the-meter integration, the capabilities of Princeton Power's platform of products and their incredibly responsive support is allowing us to address a wide range of systems sizes and emerging solution scenarios," Patterson added.
The first Glenwood project is already under construction and all of the projects are expected to be finished in five months, in time to provide power to the grid this summer.
