Last year, when we put together our predictions for 2020, we missed one very important, game-changing element: COVID-19. And today, while still in the midst of the pandemic that has turned the world on end, we once again engage our collective brainpower to foretell what the coming months will bring.

Like countless industry associations, the Smart Electric Power Organization—better known as SEPA—had planned to hold its annual Grid Evolution Summit this year in Washington, DC. But rather than kicking off as planned, the yearly event “clicked on” in mid-July, with a virtual format that included several live sessions, followed in August by pre-recorded “bonus sessions” focused on topics with a high degree of interest and relevance to today’s utility industry.

One of the topics covered Trends in Behind-the-Meter Distributed Energy Resources (DERs), and Enbala CEO Bud Vos was one of the featured speakers, providing insights on how grid operators and utilities can manage DERs at the microgrid, virtual power plant (VPP) and distributed energy resource management system (DERMS) levels. Speakers also explored how DER management trends impact value streams, market opportunities and grid services across various use cases.

At this year’s GridFWD conference delegates met for the first time in beautiful Vancouver, British Columbia, home of our Canadian headquarters. Enbala was present in full force, as a sponsor, panelist and moderator. The well-attended event covered a range of pertinent and enlightening topics including grid modernization and decarbonization.

 One such discussion, moderated by Graham Horn, Enbala’s VP, Business Development, focused on the path from DER grid presence to VPP flexibility. Graham was joined by Jeremy Twitchell, Energy Research Analyst with Pacific Northwest National Labs (PNNL), J.P. Batmale, Division Administrator at the Oregon PUC, and Smriti Mishra, Strategic Partnership Manager with National Grid.

The California Duck Curve reveals a potential costly issue for utilities and their customers. The annual peak load appears to be continuing to grow -- because it occurs after dark when there is no solar power being generated -- yet energy sales may be declining with the growth of distributed solar generation during the day. This results in the need to continue to expand the grid, but without the sales revenue to support the added capital expense, presenting a Catch-22 that utilities are struggling to overcome.

This week, we feature guest blogger Peter Asmus of Navigant Research, who talks about virtual power plants (VPPs) and their changing role in the utility industry.

The primary goal of a virtual power plant (VPP) is to achieve the greatest possible profit for asset owners—such as a resident with rooftop solar PV coupled with batteries—while maintaining the proper balance of the electricity grid at the lowest possible economic and environmental cost. The purpose is clear, but getting to this nirvana is not easy. Nevertheless, there are clear signs that the VPP market is maturing. New partnerships are pointing the way for control software platforms that can manage distributed energy resources (DER) in creative ways.

IN CASE YOU MISSED IT:

Virtual power plants or VPPs are one of the hottest topics in the energy industry today. In fact, investments in VPPs are expected to total over $68.6 billion by 2025 -- this according to Navigant Research, who has published a new white paper on the topic. 

Software advancements are enabling greatly expanded capabilities in the distributed energy resources (DERs) that can be aggregated into VPPs, which are now capable of responding to the needs of the power grid at the sub-second speeds required for instantaneous grid balancing. 

Titled Stacking Values with Virtual Power Plants in Today's Digital Power Grid: Moving Distributed Networked Energy Into the Mainstream, the paper was authored by Navigant's Peter Asmus and covers:

• The expansion and convergence of VPP market segments
• New distributed energy resource architectures
• Physical VPP grid and market interaction values
• ROIs on VPPs
