Deploying more renewables now through an energy storage-centric Clean Peak Standard

Deploying more renewables now through an energy storage-centric Clean Peak Standard

The following is a contributed article on Utility Dive by Ronald DiFelice, managing partner at Energy Intelligence Partners.

In many electric utility markets, policymakers are exploring the next generation of renewable energy policies that will deliver the most value given the new reality of low-cost solar PV, wind and energy storage. Policies that encourage energy storage to be paired with solar or wind generation can have an outsized impact because these grid assets can together deliver firm capacity into peak periods when customer costs are the highest. If implemented effectively, the results are lower costs for ratepayers, increased resiliency and reduced emissions.

NCSEA Board of Directors

Ron DiFelice of EIP has been asked to join the NCSEA Board of Directors for 2019

The NC Sustainable Energy Association (NCSEA) is a 501(c)3 non-profit advocacy organization that drives policy and market development to create clean energy jobs, economic opportunities and affordable energy. NCSEA has served as a respected, trusted and collaborative resource to North Carolina and beyond since 1978. Our goal is to cultivate a robust clean energy ecosystem that unifies and benefits all its stakeholders: consumers, businesses, the clean energy industry and utility energy providers.

Making the Case for Peak Defection and Why Utilities Should Care

Making the Case for Peak Defection and Why Utilities Should Care

“Grid Defection,” a term popularized by the Rocky Mount Institute in their report Economics of Grid Defection, has caused some trepidation among utilities executives taking a long-term look at their industry. However, little has materialized to date that gives reason for major concern. Instead, we are starting to see some selective defection during certain points of the day, specifically among non-residential customers. A term for this more near-term threat might be “Peak Defection.” Driving this movement are the improving economics of large scale energy storage, more sophisticated energy management systems, and legacy tariff structures. An additional tailwind is that intermittent renewables and energy efficiency measures are further driving up peak prices in many areas of the US (EIA).

Renewable Energy WorldWhy is this phenomenon important? One reason is that uncoordinated Peak Defection could cause more problems for the grid and make an efficient distributed energy future harder to obtain.  Another reason is that a lot of utility revenue is at stake, and tough changes to how they recoup that revenue may be necessary. However, if regulators and utilities work with their large customers to the benefit of both parties, Peak Defection can both lower power costs and increase grid stability.

Residential Energy Storage: Another Chance for Utilities

Residential Energy Storage: Another Chance for Utilities

As energy storage solutions continue to decline in cost, it is largely inevitable that distributed energy resources (DERs) will be a critical part of the future electricity grid. In the residential markets, U.S. utilities were slow to embrace the opportunity presented by rooftop solar. They now have a chance to shape the unfolding DER evolution with energy storage. Instead of ignoring or fighting the transition, utilities need to proactively find ways to lead the deployment of these new grid resources for their most vocal and visible customer base: residential customers.

Current DER market traction is largely a result of entrepreneurs and capitalists addressing electricity market inefficiencies. It started with behind-the-meter solar addressing high retail rates. Now energy storage can further decrease customer costs by optimizing behind-the-meter assets and consumption for local tariffs. As with solar, many utilities view this as a challenge to their business. But DERs have been proven to provide valuable benefits to utilities, operators, and the larger grid if planned and coordinated by the grid operator at the distribution level. These benefits include load shaping through additional supply-side and demand-side resources, improved grid resiliency, reduced emissions, and lower cost ancillary services. Indeed, utilities would likely be embracing DERs if frameworks were in place for them to share in — and get compensated for — the benefits DERs provide.

Hybrid Energy Storage Systems Get the Best of Both Worlds

Hybrid Energy Storage Systems Get the Best of Both Worlds

But calculating the true costs and benefits of energy storage is still difficult math.

Many years ago, I was part of a U.S. Air Force program with the goal of reducing the battery weight carried by airmen and soldiers by 25 percent. The Air Force Program Office, after scouring the market for the ideal battery solution, quickly learned that no rechargeable battery could meet the power density, energy density, lifetime, and size/weight requirements.

However, they did not abandon the project — they took a hybrid approach to the problem.

Batteries are typically designed for high-power applications (i.e., “sprinter” mode that provides lots of power in short bursts) or energy-dense applications (i.e., “marathon” mode that provides consistent lower power over long durations), and there are lifetime, performance, and cost penalties for using them in unintended ways.

“Support Your Local Power Grid” Why cheap solar doesn’t solve everything

2015 has proven to be another record year for clean power globally. As for 2016, wind and solar are cheaper than ever, the US just signed a major climate change agreement in Paris and everyone seems to hate coal, so look for another record year. On top of this, the “Internet of Things” and energy efficiency technologies promise to make us more efficient than ever before. With some obvious exceptions, the global market place seems to be embracing a reduced dependence on fossil fuels.

Despite the optimism, major shifts such as this can create new problems. Increased intermittency of the generation base is one of these, and while the US has found itself flush with natural gas that can provide the needed back-up power, it just isn’t that simple.

We Need a Better Way to Compare the Performance of Energy Storage Technologies

Grid-scale energy storage is getting a lot of attention this year. Pricing has come down and perceived value has come up — expanding the commercial viability of different technologies.

But the story is much more complicated. There are plenty of important technical and market-based nuances that need to be considered.

Technically speaking, battery chemistries drive performance, and they vary greatly. New nomenclature and standards are needed for comparing batteries across applications. As anyone who has cycled batteries in the lab will attest, the lifetime of the battery is dependent on how the battery is used and under what conditions.
