Con Edison To Meet Overload With Storage And Demand Management


Push aside your stereotype about Con Edison as a slow-moving public utility Goliath, and meet an energy company determined to change how it operates. Con Ed, which serves the metropolitan New York area, is taking an innovative, cost-saving approach to delivering dependable power that offers a glimpse into the future of what I predict all major utility companies will be doing in the coming years.

A case in point is the Brownsville substation that serves the boroughs of Brooklyn and Queens. Con Ed forecasts, ‘The total resource need for the sub-transmission infrastructure serving Brownsville will be 69 MW above the system's current capabilities to meet reliability requirements by 2018; the expected extent of such overload per year is approximately 40 to 48 hours per year.’

This increased demand will overload sub-transmission feeders serving the Brownsville No. 1 and No. 2 substations located in Brooklyn that support neighborhoods in both Brooklyn and Queens.

In the recent past, Con Ed would have gone the traditional, safe route of building the $1 billion worth of infrastructure at the substation the old fashioned way. Instead, the world's oldest utility company submitted a proposal to the New York Public Utility Commission (NYPUC) in July to initiate an innovative demand-management program at Brownsville.

The proposal filed with the NYPUC defers the $1 billion substation investment with about $200 million in customer-side load management programs, with an additional $300 million going toward more traditional utility investments – including some substation upgrades – in order to shed 52 MW of load from specific areas by 2018.

So in just a few short years, it is likely that the boroughs of Brooklyn and Queens will serve as a pilot program for the rest of the country with their dedicated energy storage systems and microgrids that control the availability of renewable energy sources – including solar – and combine them with battery storage technologies to provide clean and sustainable power.

What creates New York's climate of innovation? I believe it starts at the top with Gov. Andrew Cuomo, who recently allocated $250 million to ‘fund large-scale clean energy generation projects such as wind farms, fuel cells, biomass facilities, renewable biogas and the upgrading of small to medium-size hydropower projects.’ He has also revamped the Empire State's solar incentive programs under an integrated megawatt block system approach for regional solar development.

Audrey Zibelman – who was named commissioner and chair of the NYPUC last year – clearly has an innovative vision for state utility policy. I first saw her in action on a panel earlier this year at the annual meeting of the New York Battery and Energy Storage Technology Consortium, where she spoke of a new vision for Brownsville.

An expert in energy policy and Smart Grid innovation, Zibelman is formulating a policy vision for New York State that highlights the importance of clean energy and distributed resources – such as renewable generation and energy storage – which will catalyze the industry to innovate in unexpected ways.

Through efforts such as the Brownsville demand-management program, it is clear that storage will play a major role in building this utility system of the future.
