Forget Godzilla, NYC Gets Monster-Sized “Virtual” Solar Power Plant

June 14th, 2016 by  


The New York City utility Con Edison has hooked up with leading rooftop solar provider SunPower in a massive virtual solar power plant experiment. The ambitious plan seeks to recruit hundreds of home owners to link together in a combined rooftop solar and energy storage system that will connect more than 1.8 megawatts of solar power with 4 megawatt-hours of storage.

Synchronizing 300 different rooftops across a sprawling city of millions is not exactly a cakewalk. If it all works out, New York City — and the New York State power grid — could provide the model for practically every other metropolis to follow.

As the saying goes, it’s up to you, New York, New York.

The new virtual solar power plant will recruit at least 300 home owners under a power purchase type lease agreement with SunPower to install rooftop solar panels.

As an option, home owners can also have Con Edison install the energy storage component. The batteries will be provided by Sunverge Energy.  Here’s an example of the company’s sleek design approach:

So, how come Con Edison didn’t go for the Tesla Powerwall? We have no idea, but it could have something to do with Sunverge’s integrated approach to energy storage, which appears to be tailor made for the virtual power plant of tomorrow:

The Sunverge Solar Integration System (SIS) is an intelligent distributed energy storage system that captures solar power and delivers it when needed most. It combines batteries, power electronics, and multiple energy inputs in a UL-certified appliance controlled by software running in the cloud. The SIS is a utility-grade product designed for the consumer market.

To sweeten the pot, the energy storage system is both grid-integrated and home integrated. In case of a widespread power outage, the home owner can draw electricity from their own battery. Apparently it’s not enough juice to power an entire McMansion, but it will enable home owners to operate certain “essential” appliances.

What Is This Virtual Power Plant Of Which You Speak?

For those of you new to the topic, the virtual power plant concept is based on the idea that today’s software-based utility operations have advanced to the point where we don’t have to rely exclusively on large scale central power plants any more.

Instead, we can synchronize hundreds of energy storage and miniature power plants — in this case, rooftop solar panels — scattered over a wide area.

The idea behind the Con Edison venture is to create a virtual solar power plant with the specific aim of not having to build an extra “peaker” plant to supply extra power to the grid during peak use periods:

Supervisory control and data acquisition (SCADA) integration will provide remote monitoring and control, allowing Con Edison to forecast and optimize the performance and reduce the need for the utility to rely on traditional non-renewable power sources to meet peak demand.

So, What Does This All Have To Do With Fracking?

By “traditional non-renewable power sources,” Con Edison is probably referring to natural gas, which seems to be the fuel of choice for peaker plants these days.

Replacing gas peaker plants with solar energy is good news for opponents of fracking, the natural gas and oil drilling method that has been linked to serious public health impacts and earthquakes, among other side effects.

Fracking operations skyrocketed under the Obama Administration as part of the President’s “all of the above” domestic energy policy, with a significant assist by an enforcement loophole created during the Bush Administration.

That loophole is going to be difficult to close even if presumptive Democratic nominee Hillary Clinton wins the White House this fall, unless voters decide that they would also like to have more Democrats over at Capitol Hill.

If that happens, be prepared for a sea change in US energy production. Secretary of State Clinton supported the energy policies of her immediate supervisor (that would be the President), but after leaving the Administration in 2014, her policy focus quickly transitioned to renewable energy.

During a speech at the National Clean Energy Summit in 2014, Clinton stated that she favors tighter federal regulations on fracking with this result:

By the time we get through all of my conditions, I do not think there will be many places in America where fracking will continue to take place.

It’s also worth noting that Clinton’s home state of New York is among the few to institute a state-wide ban on the practice.
