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

Resiliency+ is a new blog series, which highlights the ways in which different clean energy resources and technologies can play an important part in increasing energy resiliency in New Jersey and around the country.

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.

New York Among the First States to Re-Evaluate its Utility Regulatory Framework

For most people, thinking about electricity is confined to two possible events: the arrival of the monthly bill and when the power goes out. The fact that most people don’t think about their electricity outside these two events — and let’s hope the latter is infrequent — is a testament to the robust regulation that has shaped the structure of the electric grid.

But cracks are forming that threaten the very foundation of the existing regulatory compact between utilities and customers. Extreme weather events caused by climate change and evolving consumer trends are testing the viability of the electricity system. The regulations that were crucial for maintaining stability in the 20th century are now forming barriers that make it difficult for utilities to adapt for a future that is fast approaching.

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

UPDATE: Demand Response Helped Texas Avoid Rolling Blackouts in the Face of Polar Vortex

Good news for clean energy in Texas!

The Electric Reliability Council of Texas (ERCOT), Texas’ power grid operator, presented a report to its Board of Directors this week confirming what we already knew: demand response is a worthwhile investment that strengthens Texas’ power grid.

Demand response is an innovative tool used by utilities to reward people who use less electricity during times of peak, or high, energy demand. In effect, demand response relies on people, not power plants, to meet the demand for energy. And on January 6th when the Polar Vortex hit Texas, it did just that. Read More »

Demand Response Is the Best Cure for Texas’ Ailing Grid

The Texas Public Utilities Commission (PUC) has, yet again, kicked the can down the road on securing reliable energy to power the state’s growing population. The PUC, the state agency charged with managing electricity rates, meets to securely plan for the future, yet they continue to delay planning meetings. This will benefit no one in the short or long-run. To secure reliable power and safeguard against threats of blackouts, the PUC needs to keep pace with the times and leverage technologies that require little to no water, generate negligible carbon emissions, and can respond to the call for electricity.

Last week, the PUC decided to postpone indefinitely an important meeting, originally scheduled for May, to discuss Texas’ recent blackout scares. The PUC has been in a heated debate over Texas’ electricity market structure, and in the midst of backlash from stakeholders, they have decided to push the decision onto the Legislature in 2015. This is not necessarily in the best interest of the state. Texans were asked to conserve energy several times this winter after colder temperatures forced heating units to ramp up. This request to turn down thermostats for threat of rolling blackouts came at the same time the state power grid operator assured Texans that reliability is on the upswing. But it’s time Texas faces the facts. Read More »

‘Utilities 2.0’: The Future May Be Sooner Than We Think

Last month, I had the pleasure of moderating a panel called “Utilities 2.0: The Role of Distributed Generation and Demand Response in Evolving Utility Business Models.” The topic may sound esoteric, but to the more than sixty people in attendance, and at least fifty more watching online, the event, which was sponsored by clean energy networking group Agrion, offered insight into how these options will in a not-too-distant future revolutionize the way all of us consume electricity.

The energy industry is abuzz with talk of how distributed generation, which enables consumers to draw power from on-site sources, such as rooftop solar, and demand response, which rewards customers who use less electricity during times of peak demand, are transforming the electric utility industry. A once-in-a-generation paradigm shift is already in motion, and exactly how it will play out is anyone’s guess. Read More »
