A residential transactive energy
application in Pennsylvania
What if your heating system were not just a passive residential electric load but was actively providing grid services as it was heating your home? That's exactly what's happening with specially controlled residential electric thermal storage (ETS) heaters throughout Pennsylvania.
ETS heaters convert electricity to thermal energy, which is stored in the form of hot ceramic bricks - almost like a "heat battery." A third party communicates with these heaters via the Internet to turn them on and off remotely, "charging" them at times that make sense given the wholesale energy prices and weather forecast. This type of energy load, one that is responsive to economic or other signals, is termed "transactive energy." (Here's a good read, Transactive Energy: The Next Big Deal for the Smart Grid?")
Speaking at our October meeting will be Jessica Smith and Ron Mixell of VCharge, a Rhode Island-based startup that currently controls thousands of residential ETS heaters in Pennsylvania, totaling 3MW of controllable load.
The talk will cover the basics of how electric thermal storage heaters work and explain how residential ETS heaters can be aggregated for use as a grid asset. The presentation will describe VCharge's experiences with ETS heaters in Pennsylvania specifically, including regulatory and technical hurdles.
Ron Mixell is Director of PA Operations for VCharge and Jessica Smith is Marketing Content Manager.
Hope you can join us for what promises to be a discussion of an important emerging technology. This will also be our last meeting of 2014, hard to believe!
After the meeting, please plan to stick around and chat with friends old and new. And we're always interested in your ideas for MAREA speakers, activities and services in 2015. Light snacks will be served. Hope to see you there!
