3 Baltimore Gas and Electric Company Gas Gas Efficiency Charge RIDERS Rates for service under the Company s rate schedules are subject to the Charge to recover Eligible Costs (hereinafter defined) applicable to that rate schedule incurred by the Company for conservation program design and for specific conservation programs approved for inclusion in the Charge by the Commission. The Charge is calculated for a 12-month cost recovery period beginning January 1 of each year, using the procedures described below. Calculation of Efficiency Charge The Charge for the 12-month period beginning January 1 of each year is determined for each rate schedule by dividing Eligible Costs expected to be allocated to the schedule for the 12-month period by the therm sales expected for that rate schedule over the 12-month period. Subject to prior Commission approval, the Charge may be revised at any time to include additional conservation programs or to otherwise adjust for significant changes in Eligible Costs. Details concerning the calculation of the Charge are filed with and approved by the Commission prior to their use in billing. The Charge effective with January billings is as follows: Rate Schedule Rate ($ per therm) D Eligible Costs Total costs eligible for recovery in a 12-month Charge period are the program design costs and the implementation costs of programs approved by the Commission incurred from the following cost categories: (1) Program Costs. These include program design costs, and implementation costs such as customer education, marketing, rebates and buy-downs, capital, measurement and verification (M&V) and evaluation for approved conservation programs. The regulatory asset is amortized over five years and earns a return at the rate of the Company s most recent authorized Gas System rate of return. (2) Imbalances. For each rate schedule, Imbalances are the differences between cumulative costs eligible for recovery and revenues collected through the Charge as of December 31 of each year. The estimated Imbalance includes 9 months of actual and 3 months of estimated data. An Imbalance is debited or credited against the costs eligible for recovery during the 12-months beginning January 1. During its disposition, an Imbalance earns interest at the rate of the Company s most recent authorized Gas System rate of return. Such rate is adjusted for taxes, when the Imbalance represents an under-collection of costs to the Company. P.S.C. Md. G-9 (Suppl ) Filed 11/2016/20187 Effective with January Billings
