Why VPP Software Vendors Are Vital to the Success of the Emerging Energy Cloud
The concept of a virtual power plant (VPP) means different things to different people. It’s really just a creative way to imagine the variety of grid services that can be harvested from the plethora of distributed energy resources (DER) that are rapidly populating power grids worldwide.
A VPP is the epitome of the changes transforming relationships between utilities, customers, and a host of other market participants that are building real solutions to the pressing energy and environmental challenges facing the world today. Navigant has coined the term the Energy Cloud to describe the evolution of our collective energy future. VPPs are just one aspect of this shift toward smarter, cleaner, and smaller power sources being aggregated into real-time solutions that benefit individual asset owners while contributing to the sustainability of existing infrastructure.
The Value of Software
Now that hardware assets such as solar PV panels, batteries, and other DER are becoming commoditized due to increased market penetrations and creative business models, the key to unlocking greater value from both new and existing DER is software—the fundamental technology driver underlying the VPP market.
Software is a broad category. It includes systems that connect DER in order to optimize synergies between like and unlike resources, in addition to the interface mechanics of interacting with utilities and wholesale markets for ancillary services. IT and related software is where the money is being made in the VPP market; according to Navigant Research’s Virtual Power Plant Enabling Technologies report, software spending is expected to represent nearly 90% of total VPP implementation spending by 2025. The same report also provides an analysis of the energy storage systems being wrapped into VPPs.
A sudden surge in energy storage deployments being aggregated into VPPs is tilting the market in dramatically new directions. How utilities and wholesale transmission grid operators treat energy storage as an asset may be the most important technology-related development affecting near-term commercial VPP deployments.
Navigant also recently published a Leaderboard Report ranking VPP software vendors. There is always an apples-to-apples comparison challenge with the Leaderboard format, but by stepping back and focusing on the overall trends in the market, insights bubble up to the surface.
Ranking software vendors active in the mixed asset VPP market is even more problematic than microgrid controls vendors given the lack of available transparent data on performance of software products. The lack of a universal definition for a VPP only adds another layer of issues in developing a ranking. These caveats aside, the rankings do reveal some market insights.
- The current market Leaders—Enbala Power Networks and AutoGrid—are both pure-play software companies.
- As a group, energy storage software companies ranked highest (e.g., Sunverge, Advanced Microgrid Solutions, Green Charge Networks, and sonnen).
- Large technology firms (with the exception of Siemens) generally ranked lowest as a group among VPP software providers.
Some vendors claim vertically integrated utilities are the best near-term market for VPPs, since all ancillary services required to keep the grid physically in balance are purchased by one single entity. Others argue that deregulated markets open doors to new ways of monetizing value and harness the value of diversity and competition. I believe both opportunities will help build the VPPs of the future. It will be mix of pure-play software vendors, energy storage innovators, and large global technology companies that show the way.
