Yes the $0.0373/kwh is centerpoint. They also add a $3-5 base fee for the smart meter.
Everything above that is the "energy provider". In my mind they are just the bill collector.
2000kwh should cost you $74.6 + $4. So $78. The rest goes to the energy co.
I just signed a deal with Gexa that is oing to save me $600 over my startex renewal amount. Startex would not match but they had better rates listed on powertochoose.org.
They said its for new customers only. Well there gonna need one.
