Beneficial Electrification is getting a lot of buzz. Is that the sound of humming transformers? The fan on a heat pump? This article introduces the topic with deeper dives into beneficial electrification policies, programs, and technologies in future articles. But before we go too far, let’s get down to the basics. What is beneficial electrification?
The Beneficial Electrification League, a non-profit founded by the National Rural Electric Cooperative Association (NRECA) and the Natural Resources Defense Council (NRDC) to promote beneficial electrification, defines it as “the application of electricity to end-uses where doing so satisfies at least one of the following conditions, without adversely affecting the others:
In response to concerns over climate change, electricity supplies with lower carbon emissions, and challenges with finding carbon-neutral alternatives to natural gas, propane, and other fossil fuels, beneficial
electrification is viewed by many as a key opportunity to cost-effectively address climate change.
Beneficial electrification can touch on nearly any energy using end-use that consumes fossil fuels. This includes buildings and their needs for space heating or cooling, water heating, or cooking. It can also include industrial or agricultural processes, on-road or non-road electric vehicles or facility support equipment, such as electric forklifts. The load growth opportunity that beneficial electrification can offer electric utilities is obvious. But that load growth could pose risks to peak demand or local infrastructure near its capacity. The good news is that grid resiliency is a core concept of beneficial electrification and a tool that can be used to drive utility programs or offer customers new services. From direct load control to rate design, planning for beneficial electrification can lead to innovation and become a method to drive positive customer marketing and engagement.
As we all know, electric vehicles are moving from being an exotic oddity to a more mainstream option. Driven by innovations in battery technology, electric vehicles, stationary battery storage, and control
systems are opening new markets for electric utilities. These innovations create unique challenges with grid and charging options, in particular for the DC fast charging efforts that may require transformer
upgrades, scheduled charging windows, or even additional planning staff. Utilities, local governments, and others are working to help plan the best ways to expand the market, pay for assets, manage growth,
and manage electricity loads.
There are also opportunities for beneficial electrification in the non-road, off-road, and medium/heavy duty transportation sector, providing operational and economic benefits over their liquid counterparts. Non-road electrification offers value beyond energy – fuel price stability, health and safety, reducing environmental emissions, improved performance and convenience are driving adoptions and innovation in the trucking, industrial yard equipment, transportation center, and manufacturing segments. These market segments may drive rapid changes in loads due to the scale of their operations. Whether across a market segment or at a single facility, the scale of adoption and loads can create a substantial impact. For example, electrified ship to shore cranes at port-based cities offers customers more rapid freight offloading, but also relies on very large motors likely to operate during peak time periods.
Opportunities in the building sector have substantially improved over the last decade. Cold climate heat pumps – high efficiency heat pumps that can maintain capacity in cold weather are a key opportunity for regions that have high heating demands. Heat pump manufacturers are now offering integrated controls that allow for optimizing dual fuel systems in which a building’s legacy fossil fuel system is retained for use in the coldest weather, with the heat pump taking on the dominant heating role. The efficiency gains for space cooling by using these high efficiency heat pumps are substantial – seasonal energy efficiency ratios of over 20 are common, far above the minimum federal standard of 14, creating an opportunity to create cooling energy and demand savings during the summer while providing efficient heat in the winter. Variable refrigerant flow systems are available for larger commercial buildings, while very efficient ground source heat pumps can meet the needs of small buildings up to large campus facilities.
Heat pump water heaters are another beneficial electrification opportunity. Operating two to three times as efficiently as electric resistance water heaters, heat pump water heaters are being adopted by homes and businesses. These water heaters can fit into a demand response program along side other water heaters. In addition to energy savings, heat pump water heaters offer dehumidification and cooling benefits. In the winter, heat pump water heaters will increase heat loads in a building if the evaporator is placed indoors. Innovations are ongoing, with manufacturers beginning to offer outdoor heat pump units that can operate down to -15 degrees F.
While beneficial electrification creates a very large opportunity for electric utilities, there are a number of challenges. The primary challenges are:
Despite these challenges, beneficial electrification has many opportunities. These include:
Beneficial electrification provides electric utilities with a large opportunity for growth. For natural gas utilities, electrification is a threat to sales and may cause a shift in new capital investment opportunities or upward pressure on volumetric retail rates. The growth opportunity for beneficial electrification will vary based on a region’s current markets. For example, regions with currently low market penetration of heat pumps will require substantial development of and acceptance of the building trades. The following list is a snapshot of key considerations for electric and natural gas utilities considering the impacts or opportunities associated with beneficial electrification.
There will be additional articles on beneficial electrification in future TransActions. These articles will take a deeper dive into technologies and their performance or cost considerations, utility planning and economics of beneficial electrification, and policies or market factors affecting utility programs or customer engagement.
