The Electric Reliability Council of Texas (ERCOT) is looking to expand its virtual power plant pilot project, the Aggregated Distributed Energy Resource (ADER) program. Launched in 2022, the initiative aims to harness 80 MW of flexible energy resources, primarily from battery storage. However, participation has been limited, with only Tesla and Bandera Electric Cooperative contributing approximately 15 MW so far.
Commissioner Jimmy Glotfelty, who is actively involved with the ADER initiative, stated that while progress has been made, adjustments are necessary to enhance the program’s effectiveness. “I’m happy with where we are,” Glotfelty noted, “but we need to make some changes.” His target is to have the program grow to 300 MW or 500 MW within the next few years.
As Texas experiences increasing energy demands, lawmakers have taken a keen interest in the ADER program and its potential to bolster the state’s electric grid reliability. Challenges that have limited participation were discussed during a recent Texas Senate Committee on Business and Commerce meeting. Traditionally, ERCOT has focused on larger resources, but the ADER project seeks to aggregate smaller resources around 0.1 MW.
Senator Charles Schwertner expressed concern, remarking, “It sounds like a lot of work to get 15 MW.” In response, Rickerson acknowledged the challenge but highlighted the potential for the program’s growth.
There have been difficulties in getting distributed energy resources to respond accurately to ERCOT’s grid signals, but there are plans to simplify this process moving forward. Additionally, changes are being considered around how qualified scheduling entities (QSEs) operate in the market, as current regulations impose high costs that can deter participation.
Arushi Sharma Frank, a consultant who participates in the ADER task force, emphasized that the initial limitations of the pilot program have restricted its growth. She noted, “We were far too conservative on Day One of the pilot.” With the goal of expanding the program, the task force is currently reviewing updates to its foundational guidelines to encourage more widespread participation.
Key proposed changes include increasing the total capacity for aggregations from 80 MW to 160 MW and introducing a new framework that would allow for blockier responses from various resources. This framework aims to make it easier for aggregators to manage their energy contributions and could simplify their interactions with ERCOT.
The future of the ADER program is not only about battery storage but also entails expanding the range of devices that can contribute to the initiative. For instance, many homes have smart thermostats that could potentially be integrated into the program.
Ultimately, the ongoing enhancements to the ADER pilot program will pave the way for increased participation and a more robust energy grid in Texas, fostering a pathway to greater reliability and resource management.
