Demand Response Proponents See Growth as a Supreme Court Decision Looms
Demand response (DR) energy distribution appears to be gaining momentum in the United States and elsewhere. In the U.S., however, the DR sector is awaiting a Supreme Court decision that will have great impact on the evolution of the technology, administrative and business models.
A lot is going on besides the Supreme Court case, however. Technology evolutions in two discreet areas are converging to make DR a hot topic. The tools necessary to determine where energy is being stored, where it is needed and when to deliver it is have developed over decades in the telecommunications sector. Secondly, the more recent rush of advanced battery research is making it possible to store energy and provide the flexibility necessary for demand response to really work. Mix that with the growing ability to generate energy on premises through solar, wind and other methods and a potent new distributed structure is created.
In October, Advanced Energy Economy (AEE) released a report entitled “Peak Demand Reduction Strategy,” which was prepared for it by Navigant Research. The research found that the upside is high. For instance, for every $1 spent on reducing peak demand, savings of $2.62 and $3.26 or more can be expected in Illinois and Massachusetts, respectively. The most progress has been made in the United States, the report found. Last year, the U.S. accounted for $1.25 billion of the total worldwide $2 billion demand response market, according to JR Tolbert, the AEE’s Senior Director of State Policy. The U.S. market, he wrote in response to questions emailed by Energy Manager Today, grew 14 percent last year compared to 2013.
The report painted a bright picture for the future of demand response. “The key takeaway from this report is that by passing peak demand reduction mandates into law, or creating peak demand reduction programs, policy makers and utilities could significantly reduce costs for ratepayers, strengthen reliability of the electricity system, and facilitate compliance with the Clean Power Plan,” Tolbert wrote. “As states plan for their energy future, demand response should be a go-to option for legislators and regulators.”
Though the United States dominates, demand response projects are happening around the globe. Some examples:
- Last month, Comverge’s IntelliSOURCE software was selected by the Japanese Ministry of Economy, Trade and Industry to be deployed in a demand response program by Tokyo Gas Engineering Solutions, the largest gas company in Japan. The platform will communicate curtailment signals to combined heat and power (CHP) and energy management systems in commercial and industrial buildings, Comverge said in a press release.
- In August, the Glasgow (KY) Electric Plant Board in Glasgow agreed to use Sunverge Energy’s storage devices as part of an initiative to achieve its goal of reducing carbon emissions by 25 percent. The utility, which is owned by the municipality, serves 14,000 customers in the southern Kentucky community. The Sunverge system will be installed in 165 homes.
- In July, Opower’s Behavioral Demand Response technology was selected by Hydro Ottawa. The system aids in providing end users with “highly personalized communications” before and after hours of peak energy use, the vendor said.
- Idaho Powers Integrated Resources Plan includes demand response. The document, released in June, calls for 390 MW of demand response during the “peak summer.”
There is no shortage of players for these and many other projects. In July, Navigant released a study of the competitive landscape and found 13 players: Comverge and EnerNOC (leaders), Honeywell, Schneider Electric, CPower and Eaton (contenders), Johnson Controls, Siemens, OPower, NRG and Silver Spring (challengers) and Landis+Gyr (followers).
The progress is not uniform. “The ongoing progress will be on a state-by-state basis,” Tolbert wrote. “As with all energy technologies there are states that are earlier adopters of demand response than others. The answer is actually less about which states are leading in deployment of demand response and more about why some states are outpacing others. That answer lies within a state’s policy environment. Those states with set demand response targets – requiring utilities to reduce load during periods of peak demand – are where we see the greatest market penetration.”
The precise path for demand response is not clear. The Supreme Court case focuses on whether the federal government – through the Federal Energy Regulatory Commission (FERC) — or the states should control how demand response programs are administered. A good rundown is available from The American Enterprise Institute.
While the Supreme Court’s decision will be a major milestone and signal the path of evolution, Tolbert wrote that it won’t derail demand response. “…[W]hile the best structure for realizing the full potential for demand response is for there to be state standards paired with participation in wholesale markets the fate of FERC Order 745 at the Supreme Court should not deter states from moving rapidly ahead with development of their own programs. Demand response is a technology that is here to stay.”
