Harold,
Thanks for posting these letters!
The part of the Document in regards to running a 40 Watt Incandescent Lamp for 2.5 Hours, costing 1¢; equates to 10¢ per Kilo Watt-Hour (KWH).
Base costs of True Power has not changed very much since then.
Basic Lifeline Charge for me is $0.099 per KWH, and Non-Lifeline rate is $0.1462 per KWH.
The most significant changes in Billing Rates would be the Delivery Charges, and the various Tier Level Charges - being applied to Residential Customers, as well as Commercial / Industrial Customers.
