The Federal Energy Regulatory Commission (FERC) describes demand response as “changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.”

There is quite a bit to unpack in that definition, but put simply, demand response is little more than a way of financially motivating customers to reduce their energy use when electricity is particularly scarce and expensive or when the wires are overburdened (check out EDF’s other blog posts and resources that go into more detail). The end result is a more efficient electric grid which is less overbuilt and less dependent on inefficient fossil-fuel plants that are often uneconomic to operate and highly polluting, but may be called upon when all else fails.

Unlike large, centralized power plants, distributed generation and microgrids create electricity on or near the premises where it can be primarily used. Solar panels on rooftops, for example, are a form of distributed generation: they create electricity that can be used in the same location where the renewable energy is generated. Microgrids are similar – systems that serve a specific energy consumer, such as university campuses, with on-site energy generation that can operate both independently from (i.e. ‘islanded’) and connected to the larger energy grid.

A National Renewable Energy Laboratory (NREL) study found that distributed generation and microgrids, “are integral to energy resiliency.” With the right enabling technology, distributed generation and microgrids have the potential to ‘island’, meaning that they can function separately from the main electricity grid. In other words, in the aftermath of a storm or during a blackout, distributed generation and microgrids are able to keep power running. The importance of this technology cannot be understated. Without it, electricity that has the potential to work during a system-wide blackout – like solar power or energy storage – will be rendered powerless. Distributed generation and microgrids provide the pathway for these clean energy resources to function during and after a natural disaster. Read More »

Resiliency+: Renewable Energy Can Boost Grid Resilience in Vulnerable New Jersey

BAPV_solar-facadeRenewable energy, such as solar and wind power, provides clean and sustainable power to our electricity grid. But it also offers other benefits beyond environmentally-friendly electricity. Renewable energy can increase energy resiliency by keeping the lights on, including at critical facilities in the wake of a natural disaster. That’s why it has the potential to play a particularly pivotal role in New Jersey, which is vulnerable to vicious storms such as Superstorm Sandy.

Renewable energy, unlike other forms of energy, is less vulnerable to sustained disruption. Other, more traditional forms of energy, such as fossil fuels, require an input (coal, oil and gas, etc.) that needs to be shipped, often via pipeline, to create electricity, leaving them vulnerable to a natural disaster that might interrupt transport. On the other hand, renewable energy has the ability to generate stable, on-site power from sources such as solar and wind when it operates from a microgrid. A microgrid can generate power both connected to and independently from the main, centralized grid. They can vary in size, providing power to several city blocks or to an individual home, but microgrids have the unique potential to “island” from the main electricity system. This is important during and/or in the wake of a natural disaster like Superstorm Sandy because this autonomous electricity system is able to power local buildings regardless of whether or not the main electric grid is down.

Resiliency+ Series: A Highlight of Clean Energy Technologies that will Strengthen New Jersey’s Electricity Grid

Improving energy resiliency has become critically important throughout the United States – particularly in the Northeast, where devastating events like Superstorm Sandy debilitated our electricity grid. States are searching for ways to create a stronger, smarter, and more flexible energy infrastructure, so that storm damage can be minimized and restoration times shortened. Doing so, however, is no small task. Ensuring that the lights stay on in critical facilities like hospitals, emergency shelters, and water treatment facilities requires innovative thinking, as well as a forward-looking instead of reactive approach to our power sector.

The issue is critical for New Jersey

New Jersey was among the worst hit when Superstorm Sandy pummeled the East Coast eighteen months ago. The state suffered more than $30 billion in damage, most of it along the Jersey shore, while an estimated 2.6 million households across the entire state lost power, many of them for weeks. Five days after Sandy hit, a third of New Jersey’s homes and businesses still did not have electricity. Read More »
