Demand Energy’s recent announcement of 1MW of battery systems in Manhattan residential high-rises could herald the advent of a significant new niche for energy storage.

Earlier this month the Washington State, US-based storage system developer confirmed its customer Glenwood was including behind-the-meter battery systems in buildings across its portfolio of properties, starting with 10 systems immediately.

The move comes as New York utility Consolidated Edison (or ‘Con Ed’) and the New York State Energy Research and Development Authority (NYSERDA) set about introducing measures to cope with the possible closure of a nuclear power plant.

The Indian Point Energy Center delivers up to 15% of Con Ed’s 13.2GW peak power but is currently reaching the end of its original life span. One reactor has already shut down.

The plant operator, Entergy Nuclear Northeast, is applying for licence extensions for two remaining reactors. The licence for the second unit expired in 2013. The licence for the third expires at the end of this year.

The demand side of the problem

Faced with a mismatch between falling generation and continued increases in New York’s energy consumption, Con Ed and NYSERDA have put together a package of measures that attack the demand side of the problem.

Ioxus and EnerSys mix technologies

Under a new agreement, EnerSys and Ioxus will develop and market new products that leverage the strengths and benefits of combining the former’s battery technologies with the latter’s ultracapacitor expertise.
 The deal will focus on creating products to address regenerative braking and energy recovery in the material handling market, and other major markets, including generators, automotive and heavy trucks, critical and cold starts, and energy storage/power conditioning.

The companies hope that by combining their technologies they will be able to enter vertical markets in need of high-performance, extended energy storage life under harsh environmental conditions, including some automotive markets.

EnerSys unveils grid scale solution

EnerSys recently announced that it is entering the large-scale energy storage market with its new OptiGrid Stored Energy Solutions, a turnkey megawatt hour scale energy management system for utilities and large industrial applications.

John D. Craig, company CEO, remarked that the opportunity comes from a forecast large-scale energy storage growth over the next 10 to 20 years of as much as US$200-600 billion, globally. He added that the company believed that it could reach two to four gigawatts as soon as 2016.
