The commissioner of the Federal Energy Regulatory Commision (FERC), John R. Norris, recently issued a statement (called a Notice of Inquiry) focused on energy storage. Here's what he had to say: “I want to thank the team for their hard work tackling the difficult issues addressed in today’s Notice of Inquiry (NOI). While the NOI is not focused exclusively on storage technologies, issues unique to storage devices are a major part of it. As the questions we pose in this NOI demonstrate, new storage technologies present some interesting challenges for current Commission policies and practices, and I appreciate our staff’s efforts in helping us sort them out.
I am extremely interested in storage technologies and the benefits they could bring to our electricity system. I speak often about the numerous challenges we see facing the electricity grid. The increased penetration of renewable resources on the grid, the need to update our aging infrastructure to accommodate new demands, and the pressure that environmental regulations will put on existing generation assets – these drivers are bringing significant change in the electricity sector. With that change will come associated costs to consumers, and for that reason, we should be looking at any and all potential solutions to help us manage this change in an efficient and sustainable way.
Storage technologies, if more fully developed and utilized, hold great promise to help us efficiently address these challenges and hold down costs to consumers. As the Electric Power Research Institute (EPRI) noted in a white paper on storage technologies issued last year, energy storage systems have a key feature that transmission and distribution systems do not – they “can move energy through time, providing it when and where it is needed.” This feature, as EPRI points out, can help balance variable renewable resources, increase reliability, and improve the utilization of existing assets.
Given the significant potential benefits of storage technologies, the Commission should strive to ensure that our regulatory policies foster, rather than inhibit, their growth. Today’s NOI touches on a variety of key issues that we need to address to be sure our regulatory policies and practices do not stand in the way of storage technology development.
One issue that is important to me is that we recognize that storage technologies may provide multiple services, and thus multiple benefits, to the electricity grid and wholesale electricity markets. The Commission’s policies should be geared toward fairly compensating these technologies for the full range of benefits they will provide when deployed. Achieving this outcome will help ensure that the rates that customers pay for these benefits remain just and reasonable.
By analogy, I use the example of paying for the costs of a new stadium in a city. That stadium provides a venue for multiple events, from basketball games to rock concerts, providing multiple services to users and adding to the overall value and benefit to the community. This value would be lost if the stadium only charged for admission to basketball games; the ticket price for basketball games would necessarily be too high, and other events would not take place in the stadium without compensation – all to the community’s detriment. Instead, the stadium should seek to charge a fair price for each event (i.e., service) it offers. We need to think about storage in the same manner.
One service that new storage technologies could provide is frequency regulation. In February of this year, we issued a Notice of Proposed Rulemaking on Frequency Regulation Compensation, where we proposed to require RTO/ISOs to adopt new mechanisms to compensate resources for frequency regulation in a way that rewards them for quickly and accurately responding to the needs of the system. As I noted at the time, this pay-for-performance mechanism could result in the need to procure less regulation capacity and in improved utilization of existing supply resources, efficiencies that will benefit the grid and consumers over the long-term. While I supported this initial focus on the RTO/ISO markets, I noted that we should also look at how frequency response resources are procured and compensated in non-RTO/ISO regions. I am pleased that today’s NOI seeks comment on these issues. I hope that the comments we receive will shed light on efforts that we can undertake in those areas to create similar efficiencies and benefits for the grid and consumers.
I am interested in learning more about all aspects of electric storage technologies, and what the Commission can do to support – and avoid hindering – their development. Good, robust comments on this NOI will help us learn more. To the extent industry and the public have information they would like to share with me and my staff, please do not hesitate to contact us.”
This blog is focused on trends in battery technology and other types of energy storage that are used for smart grid load leveling and stabilization, and as back-up power for renewable energy sources such as photovoltaics/solar power, hydro and wind energy. Trends in lithium ion batteries, lead-acid, metal-air, NaS (sodium sulfur), ZnBr (zinc-bromine) batteries will be covered, as well as compressed air energy storage (CAES), flywheels, fuel cells and supercapacitors.

Interesting read... wonder what kind of an impact this statement will have on these new electric technologies.ReplyDelete
