Demand Response Has Been Part of America’s Energy Plan for 40 Years. Why Should the next 40 be any Different?

April 22, 2021

The idea that reducing a watt of energy on the demand side can be just as valuable as generating one on the supply side in a time of grid stress is hardly new. Nor is the idea that such a solution helps thwart both energy-related and environmental crises. 

The origin of demand response can be traced to roughly forty years ago when both the US and the world grappled with many of the same energy and environmental issues we are still trying to solve today. 

Let’s take a trip back to the mid-late 1970s and see if a few things don’t look and sound familiar.  

The oil crisis of 1973 sent shockwaves throughout the world, raising concerns on the security of electricity supply in the US while pointing to a need to diversify the nation’s power generation mix away from a fossil fuel dependency and toward a mix with a greater share of renewable and clean energy sources. 

Global environmental awareness had grown to a movement large enough to be seized upon by newly-elected American president Jimmy Carter who, within a month of taking office, donned a cardigan sweater, sat before a roaring White House fire, and urged Americans to join him in conserving energy in a nationally-televised fireside chat.

During that broadcast on February 2, 1977, the president related how a particularly harsh winter had depleted the domestic supply of natural gas and fuel oil. He warned of dark consequences that awaited the most powerful country on earth if we as a nation failed to devise a sound energy plan for the future. 

Sound familiar?

The 39th POTUS didn’t outright cite demand response as a means to a profitable and sustainable end that night in 1977, but he did allude to the Public Utility Regulatory Policies Act (PURPA), a piece of legislation that would be enacted in 1978 to promote more competitive energy markets in the US by allowing “non-utility generators” to participate in them. 

The act would prove to be a landmark piece of legislation, setting the country on the road to conservation and the development of clean and renewable energy sources. It would also open the door to demand response as a viable solution to keeping both the electric grid and the environment in balance. 

That open door paved the way for the deregulated, competitive energy markets we have today to replace the vertically-dominated regulatory ones that had existed for most of the 20th century. It also would prove to be the seed that would soon mature and bear the lucrative fruit of modern demand response. 

Fast forward back to the present. Federal legislation is still working to ensure energy markets remain competitive with clean and renewable energy sources securing a just and reasonable position place in them. 

Order 2222 from the Federal Energy Regulatory Commission (FERC) is a case-in-point. The Order is the latest in a series of directives aimed to create a fair balance between traditional generators on the supply-side and distributed energy resources seeking to enter markets on the demand side.   

Issued in September 2020, Order 2222 calls for the removal of barriers preventing distributed energy resources (DERs) from competing on a level playing field in the organized capacity, energy, and ancillary services markets run by regional grid operators.”

Order 2222, widely hailed as a landmark achievement in the history of the energy industry is about more than just creating more competitive markets. By allowing DERs, including demand response, their just seat in the marketplace, Order 2222 enables the US electric grid to take a giant leap toward a cleaner future. 

Consider this recent data on demand response performance in the US:

In 2019, the most recent year for which the data is available, the combined wholesale demand response capacity of all regional system operators in the US grew to 27,000 MW. 

How much environmental pollution did all that demand response save the country in 2019 by providing a resource that would have otherwise been supplied by a traditional “peaker” plant?

According to the EPA, the 27,000 MW of capacity from all commercial DR participation in the US in 2019 prevented the greenhouse gas emission equivalent of what an average passenger vehicle would produce were it to drive a little more than 142 million miles.

That same total of reduced load roughly converts to the carbon dioxide emission equivalent of 63 million pounds of coal being burned. 

In 2020, CPower’s more than 1,700 customers contributed more than 4,000 MWs of capacity to demand response,  effectively reducing the energy equivalent of 7 million pounds of coal that would otherwise have been burned and released into the environment. 

Helping the grid stay balanced and keeping the air clean aren’t the only benefits to demand response. 

The global demand response market is projected to value at USD $24.71 billion by 2022, an increase from the $5.7 billion valuation of the same market in 2014,  according to a recent report published by Million Insights market research firm.

Much has been made in this publication and others in the energy industry about the evolving electric grid and demand response’s role in helping to bridge past, present, and future. 

As you read these words, energy markets and electric utilities across America are refining their demand response programs and introducing new ones, providing organizations with a lucrative and socially responsible way to use their energy assets to support grid reliability in this critical time of transition. 

America opened the door for demand response nearly forty years ago. Closing it now (even just a little bit) would be a step toward the past in a time when the country should be crossing the bridge to energy’s future.

Power Shift: How DERs are Creating a New Balance of Power (Webinar)

November 11, 2020



What will electrical power consumption in North America look like in 2050? Will centralized power generation still dominate, or will distributed energy resources–DERs–shift the balance of power generation to the energy end consumer? Our presentation takes “a look back” from the future to show how expanding DER implementation is laying the groundwork for a new balance of power, freeing organizations to independently pursue sustainability and reliability goals, and how monetizing DER energy assets is accelerating that shift. Our case study reveals how one university monetizes solar, battery storage, and demand-side energy management strategies to power its future, today.

Learning Objectives:

  • Examine How the “balance of power” will shift from generators and utilities to the end energy consumer over the next decade.
  • Explore the ways in which flexible demand and aggregation at the consumer level will change the grid infrastructure.
  • Investigate the impact that distributed energy resources (DER) and microgrids will have on the state of grid modernization.
  • Identify additional renewable resources, beyond solar and wind, that will see the greatest increase in adoption for both supply and demand of electricity.

Watt’s Up With Backup Generators?

September 30, 2020

Simplifying back-up generation rules, permitting, and demand response participation.

Renewables are here and continue to displace traditional coal resources on the grid. Battery storage is compelling and becoming more cost-effective — but it is still not a full-proof, scalable solution. Utilities are battling the challenges of grid intermittency amidst infrastructure challenges to support renewable penetration. All of this to say, the tried-and-true back-up generator is still the go-to resource when it comes to energy resilience and still remains a misunderstood energy resource.

Join CPower’s back up generation and demand response experts Arusyak Ghukasyan and Michael Mindell for this 30-minute panel to learn and understand topics including:

  • How generators can earn revenue for your organization
  • The rules and policies for BUGs at the federal, state, and local level
  • Common myths about using BUGs for ‘non-emergency’ situations like demand response and testing under load
  • What industries, markets, and programs are more favorable to BUGs for revenue
  • How to fund and finance generator upgrades or replacements

The Push for Renewables in New York

April 10, 2019

One of the Reforming Energy Vision’s primary goals includes renewable sources generating 70% of the state’s electricity by 2030. To do that, the New York grid seeks to implement distributed energy resources into its fuel mix.

How might New York’s energy market be redesigned to incorporate DERs like solar, energy storage, and others?

NYISO’s proposed changes meet opposition

In 2018, the NYISO proposed changes to the ICAP Capacity Market for how long a resource must be able to run to be eligible to be paid the full value of capacity.

Using the results of a study on energy-limited resources by GE Consulting (GE), the NYISO initially proposed that resources would need to be able to run for 8-hours in order to obtain full capacity value. The NYSIO then proposed it would allow resources that can perform for shorter durations to be paid a fractional portion of the capacity value as follows:

8-hrs=100%

6-hrs = 75%

4-hrs = 50%,

2-hrs =25%

A group of demand response and energy storage providers, including CPower, challenged the GE study’s findings.

A formal review of the GE study by Astrapé Consulting revealed “several flaws in the assumptions and methodology that influenced the study results to show a decreased capacity value for shorter-duration resources than would likely be expected.”

Skepticism of the GE study’s results quickly spread among key New York energy stakeholders, including DR providers, energy storage developers, C&I customers, environmental groups and various trade associations.

These stakeholders submitted a joint letter to the NYISO executive team and board of directors requesting “all market design changes relating to the GE Study results (including any changes to the SCR program) be removed from the DER Roadmap.”

So where does that leave New York?

Potential changes in the New York Energy Market

While there is an ongoing debate about the future of New York’s capacity market, there are no major regulations or market design changes yet announced to take effect in 2019. That could change pending the outcome of an April vote (more than a month away as of this writing) among New York’s energy stakeholders.  

That means, for example, the Special Case Resource (SCR) demand response program will continue to operate under its current parameters, including a four-hour duration requirement.

As far as the DER wholesale market goes, New York is in wait-and-see mode. DERs, especially battery storage, and renewable energy sources are a key component of the REV’s drive toward New York’s energy future.

New York, like several other US energy markets, is faced with the question of how to value distributed energy resources in its marketplace.

The question of DER valuation is being debated by the NYISO and various energy stakeholders in the state. As of this writing, there is no definitive timetable for when the debate will conclude and regulations for DER valuation will be enacted.

Energy Storage

New York has taken its place alongside California, New Jersey, and Massachusetts as a first-mover in establishing energy storage targets.

In June 2018, Governor Cuomo announced an energy storage roadmap that set New York’s storage target for 1,500 MW by 2025. According to the roadmap, that ambitious goal could elevate to 3,000 MW by 2030.  

At the state level, New York has recognized the need to fund storage projects instead of subsidizing them. Last June, Governor Cuomo committed $200 million from the New York Green Bank to fund storage investments that will help integrate renewable energy onto New York’s grid.

Funding opportunities for storage abound with plenty of state money being made available for storage development.

But without certainty on the wholesale market side and established rules concerning dual participation between markets, meeting the state’s ambitious storage goals will continue to have its challenges.

The key energy players in New York will need to resolve these issues before any substantial investment from the private sector will take a position on energy storage. The NYISO is targeting April 17, 2019, for a vote on market design to accommodate DER integration into its wholesale markets.

Has California finally solved “The Duck Curve?”

California experiences a daily spike in energy demand in the early evening when renewable sources like solar go offline and residents come home from work and increase their energy consumption by flipping on their air conditioning, turning on their lighting, doing laundry, charging electronic devices, and engaging in other energy-consuming activities.

When charted on a graph (see picture), the shape of California’s daily electrical consumption resembles a duck. Analysts have noted the duck’s belly is getting fatter with each passing year, meaning the evening net load ramp when flexible resources are needed to account for the spike is becoming more extreme.

A Steady Diet of Storage

The duck’s belly may not get fatter in 2019, but it’s still going to be heavy.

To help alleviate grid stress associated with evening load ramp, CAISO is developing a load-shifting product under the third phase of CAISO’s Energy Storage Distributed Energy Resource (ESDER) that would be the state’s first product that will pay a resource to consume energy to soak up excess generation during negative pricing periods.

CAISO’s load-shift program embodies California’s desire to bring clean resources to the forefront of grid reliability by storing excess clean energy and making it available for future use.

The program, championed by the California Energy Storage Alliance (CESA) among other energy storage companies, also aims to reduce the number of solar curtailments needed to offset the ill effects of negative pricing caused by a large solar surplus on CAISO’s system.   

The two big questions on the minds of organizations that have implemented or are thinking of implementing energy storage are:

  1. When will the CAISO’s load shifting product be available for participation?
  2. How will these storage resources be valued in the wholesale market?

The short answer to the first question is the program is currently going through the FERC approval process and is scheduled to go into effect in November 2020.

As far as how storage will be valued in the wholesale market? It’s too early to tell right now, but expect California to continue to work to provide value for all the services storage can provide.

Webinar (2/14/2019): Dispatchable Dollars: How Demand Response Creates Revenue Opportunities For DER

January 28, 2019

Distributed Energy Resources (DER), including storage, are proliferating the world of energy management in a big way. Today, these assets are primarily implemented to provide operational resilience and demand management; however, additional opportunities are rapidly evolving.

As intelligent application of DER assets increases for commercial and government sectors, the opportunity to leverage these same assets into revenue generating channels also increases.

Through programs like demand response, your DER assets become vehicles for saving and earning, which increases ROI, shortens project payback periods or helps fund other energy projects, all while providing greater support for grid reliability.

Join DER and storage experts from CPower Energy Management and Stem and learn about:

  • The evolution of DER as a mainstream asset
  • Market drivers for DER growth and opportunity
  • Planning intelligent DER and Demand Response integration
  • How commercial orgs have added 30-50% to the value of DER projects by using flexible infrastructure, such as storage, to participate in DR programs like DRAM in California
