In response to 140719: electric bills, posted by Jeff N on Saturday, 11 March 2017, at 1:23 a.m.
The bill for Jeff is correct if during the month he used 538 kWh of electricity from HELCO and sent back to the grid 512 kWh from his solar array. Under the old Net Metering arrangement the total bill would have been under $30 as the credit for the 512 kwh contributed would have cancelled nearly all of the energy taken from the grid. Under the Service Grid Supply arrangement in effect here, however, you are paying twice as much for the electrons that flow into your meter than what you receive in credit. Plus you open yourself up to all those extra charges that are based on the amount of energy purchased.
With numbers from the PUC rate schedule (https://www.hawaiianelectric.com/Documents/my_account/rates/hawaii_electric_light_rates/helco_rates_sch_r.pdf
NON FUEL CHARGE (essentially the cost of the infrastructure)
next 238 kWh -at- $0.145537/kWh = $34.64
BASE FUEL CHARGE
538kWh -at- $0.162487/kWh = $87.42
GRID SUPPLY CREDIT
512 kWh -at- $0.1514/kWh = $77.51
Are my calculations of energy you bought and contributed correct?
Δ KWH used OR meter charge for me, not both
