Demand Energy last month announced it has been selected by New York City’s distribution grid operator to build 2.5MW and 10MWh of energy storage projects.
The Enel Group subsidiary said in a press release that the projects will deliver behind-the-meter benefits to commercial and industrial (C&I) customers and provide support to the City’s electricity grid.
The storage systems, which will be installed in 11 commercial locations across the City, will be controlled by the Demand Energy’s Distributed Energy Network Optimization System (DEN.OS) intelligent software control platform.
The projects are part of a programme that aims to reduce electricity demand during peak hours and provide grid capacity relief as an alternative to more expensive electricity network buildouts, according to Demand Energy.
“We’re proud to be selected to expand the deployment of our DEN.OS-powered storage solutions,” said Jeff Damron, vice president of sales at Demand Energy, in press materials.
Value creation and demand reduction
He said the projects will “demonstrate the value creation and demand reduction capabilities of intelligent energy storage across New York City” and claimed Demand Energy now had “unequalled” experience in the city.
“We look forward to installing and operating these projects and continuing to participate in the ongoing transition of New York’s power grid to a decentralised, digitised and more resilient network,” he said.
Electric load relief is needed in New York City, especially during peak summer periods, to avoid over-burdening the city’s grid and preventing power interruptions and cutbacks, Demand Energy said.
The city has programmes in place, using advanced technologies such as energy storage, to reduce existing electric demand or to avoid expected growth in peak system demand.
Demand Energy’s storage systems have the potential to save money, reduce emissions and speed up the implementation of a more flexible and sustainable alternative to conventional infrastructure projects, the company said.
A five-year track record in New York
Demand Energy has a five-year track record of installing systems in New York City to provide load relief on peak power days.
The company has deployed storage systems across more than a dozen sites in Greater New York City, including the city’s first solar PV-plus-storage microgrid, all enabled by DEN.OS.
The platform manages storage and other distributed energy resources to reduce peak demand, while maximising economic returns from behind-the-meter energy systems, said Demand Energy.
The new business announcement came shortly after Demand Energy bagged an Energy Storage North America (ESNA) Innovation Award for Distributed Storage, for its Marcus Garvey Apartments solar-plus-storage microgrid.
The project is New York City’s first-ever multi-resource microgrid in a low-to-middle income housing development, and the first deployed under Con Edison’s Brooklyn-Queens Demand Management programme.
Solar, fuel cells and storage
It includes 400kW of solar PV, a 400kW fuel cell and 300kW/1.2MWh of storage, managed via DEN.OS.
“We are honoured to be recognized with an ESNA Innovation Award for our Marcus Garvey Apartments microgrid project,” said Gregg Patterson, head of Demand Energy, in a press note.
“This system benefits the property owners and residents through enhanced resiliency, clean operation and energy savings.
“It also aligns with the state’s vision of moving to a two-way distributed grid that serves longer-term energy goals.”
ESNA celebrated the winners of its 2017 Innovation Awards during a reception on August 9 at the San Diego Convention Center, San Diego, California, USA.
Demand Energy maximises returns
The prize and the new capacity awarded in New York City show how Demand Energy is continuing to benefit from having developed a software system that maximizes the economic returns of behind-the-meter storage systems.
The DEN.OS platform was designed as a scalable end-to-end system that delivers value across a project’s life cycle, and can support utility-side, behind-the-meter and microgrid projects, Demand Energy said.
It is thought to have been one of the key factors that led to Demand Energy being snapped up earlier this year by Enel Group, a utility giant which operates in over 30 countries across five continents.
Enel is the largest utility in Europe in terms of market capitalisation and figures among Europe’s leading power companies based on installed capacity and reported earnings before interest, taxes, depreciation and amortisation.
Enel’s green energy division, Enel Green Power, is a leading multinational renewable energy player, managing 39GW of wind, solar, geothermal, biomass and hydropower plants in Europe, the Americas, Asia, Africa and Australia.
