What’s the difference between DERs and a DERMS?  And what’s the definition of a DERMS versus a VPP?  Just as important what difference does it make?

“What’s best for players individually is not what’s best for the public and for the system as a whole.”

This comment reveals an issue that may soon be a problem.

For most of the 130-year history of the electric grid, utilities have charged residential customers for energy used and have NOT charged for peak power demand, as they do for commercial and industrial accounts.
