The FERC approved a final rule that will enable distributed energy resource (DER) aggregators to compete in organized wholesale electricity markets.  DERs are located on the distribution system or behind the customer meter and include electric storage resources, intermittent generation, distributed generation, demand response, energy efficiency, thermal storage, and electric vehicles and their charging equipment.  Aggregators will now be able to aggregate multiple small DERs as a single resource to compete in the markets, smoothing the way for many more of such resources to enter the wholesale market.

The Federal Energy Regulatory Commission (FERC) approved tariff terms for a Regional Transmission Operator (RTO) to treat electric storage resources as transmission facilities under certain circumstances.  Previously, FERC approved only one case-specific proposal to treat storage as transmission.  Treatment as a transmission facility provides additional deployment opportunities for storage resources and allows cost recovery through cost-of service transmission rates instead of relying entirely on energy market revenues.  Commissioner James Danly, however, dissented from the tariff order, preferring to maintain the bright line between generation and transmission previously established by FERC.

The Federal Energy Regulatory Commission (FERC) has announced two conferences to address issues raised by the increasing deployment of electric storage resources and their use in electricity markets.  One conference will address a proposal by a Regional Transmission Operator (RTO) to treat an electric storage facility as a transmission-only resource if it can resolve specific transmission issues.  The second conference will discuss issues raised by hybrid resources, i.e., a storage resources paired with a generation resources.  These conferences should be of interest to a wide range of electricity market participants, including utilities, generation companies, customers and investors in storage and other electricity resources.

Electronic devices and their components marketed in the European Union and European Economic Area are subject to a morass of environmental and product safety requirements that is only likely to increase with the EU’s implementation of its Circular Economy Strategy in the near future.  The requirements apply to all types of equipment, from sophisticated information technology equipment, to military equipment, aircraft components, electronic medical devices, household electronics, consumer devices, and industrial tools.

In a project that the World Bank hopes will be a catalyst for implementing its climate change strategy in low and middle-income countries, Eskom, South Africa’s 100% state-owned electricity utility, will launch a tender for a 1.4 gigawatt-hours battery energy storage system (“BESS”). The tender will likely be issued in the first or second quarter of 2020, pending final governmental approval. The completed BESS will have a daily capacity of 1.4 gigawatt-hours of energy output (which is sufficient energy to power 1.4 million homes for an hour). The project is the first of its kind on the African continent.

Taking another step toward a comprehensive policy on the participation of electric storage resources and other distributed electric resources (DERs) in wholesale markets run by independent grid operators, FERC has requested additional comments on its proposal regarding aggregating DERs and their potential effects on the bulk power system.  FERC’s request follows up on a technical

Electric storage resources such as batteries and flywheels are shaping the grid of the future. The ability of these resources to absorb and discharge electricity gives the resources operational flexibility that allows them to provide a variety of services to help keep the power grid in balance.  Energy storage installations in the U.S. grew 100% in 2016Most of the new resources were utility scale but 25% were commercial and residential systems.

As discussed previously in this blog, FERC issued a Notice of Proposed Rulemaking (NOPR) intended to knock down barriers to storage resource participation in the organized wholesale electricity markets administered by Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs).[1]  FERC’s proposal would require each RTO to revise its tariff in two ways:

  • Establish market rules that recognize the physical and operational characteristics of storage resources and accommodate their participation. Storage resources that participate in wholesale markets must do so under rules designed for other types of resources.
  • Allow distributed energy resource aggregators to participate in the markets. Individual distributed energy resources may be too small to meet minimum size requirements or have difficulty satisfying operational performance requirements of the markets. Allowing these resources to participate through aggregations can enable them to satisfy requirements that they could not meet on a stand-alone basis.

FERC received comments on its proposal from more than seventy entities across a broad  spectrum of the industry.  This post summarizes the major issues raised in the comments.

A previous post on this blog reported a complaint by an electric storage resource owner that FERC must reform a Regional Transmission Organization’s (RTO’s) tariff with respect to the treatment of storage batteries.  In response, FERC issued an Order that requires the RTO to adopt rules that allow storage resources to participate in all of its markets and that account for those resources’ physical and operational characteristics.  The Order is significant because it breaks down barriers to the participation of storage resources in energy, capacity and ancillary services markets in an RTO whose rules are shown to violate the policies proposed in FERC’s Storage NOPR.
