Griddy has saved me over 900 dollars compared to the Texas average.
I pay wholesale rates and a small monthly subscription fee, plus delivery by the local utility. My bill last week(mid October) was 25 dollars. Just avoid using appliances during peak hours like 3-5pm M-F.
Rates are higher at peaks, but Griddy sends you notices if there is price surge, which are rare. When I lived in California, it was expensive monopolies and I paid about 4 times what I’m paying griddy.
