Goal: A competitive electric market that offers customers choice and lower prices: A LEVEL PLAYING FIELD.

What Is Needed:

Cost element: Set By: IOUNew Entrants
GenerationPower Exchange Cost + Profit Cost + Profit
Transmission FERCCost + Profit Cost
Distribution CPUCCost + Profit Cost
CTCCPUC CostCost
Public Goods Charge Legislative CostCost

Level playing field can only be created by:

  1. Unbundling the distribution costs so the IOUs do not automatically pass through their overhead, marketing and profits.

  2. Providing a competitive transition credit to new entrants to encourage competition.

  3. Offering customers incentives for switching to new entrants, as in New Hampshire.


Comparison of Billing Costs Between New Entrants and IOUs

New Entrant
IOU
Monthly Cost per Customer
Usage in kwh 500500
Supplier's cost of power in kwh: $0.03 $0.03
Total cost to obtain power: $15.00 $15.00
Total Billing/Customer Service $2.50 0.25
Total Cost To Serve Customer $17.50 $15.25
Cost to Customer per kwh, No Profit $0.0350 $0.0305
Cost with 10% profit $0.0385 $0.0336

(1) IOU's billing cost for generation is a one-line addition to its distribution bill, thus very low cost.

(2) New entrant's cost does not include overhead, marketing and other costs, much of which the IOU is recovering in the distribution charge.

A level playing field could be created by following the telecommunications model. The new entrant will bill the customer for the total power costs, including generation, trasnsmission, and distribution. The new entrant will then remit distribution and transmission costs to the IOU. The customer will get one invoice; the IOU distribution costs will be only the distribution and maintenance of power.
