DR 97-250 CONCORD ELECTRIC COMPANY and EXETER & HAMPTON ELECTRIC COMPANY Fuel Adjustment Clause and Purchased Power Adjustment Clause Order Approving Charges O R D E R N O. 22 ,816 December 31, 1997 Appearances: LeBoeuf, Lamb, Greene & MacRae by Scott J. Mueller, Esq. on behalf of Concord Electric Company and Exeter & Hampton Electric Company; and Henry J. Bergeron and Todd M. Bohan for the Staff of the New Hampshire Public Utilities Commission I. PROCEDURAL HISTORY On December 2, 1997, Unitil Service Corporation, (Unitil), on behalf of Concord Electric Company (CEC) and Exeter & Hampton Electric Company (E&H) (collectively the Companies), filed with the New Hampshire Public Utilities Commission (Commission) revised tariff pages, supporting testimony, and exhibits for proposed revisions to the Companies' retail fuel adjustment clauses (FAC) and purchased power adjustment clauses (PPAC) and short-term purchased power rates for qualifying facilities (QFs) for the period of January 1 through June 30, 1998. On December 10, 1997, Unitil filed an amended FAC/PPAC filing to update the filing made on December 2. As stated in the letter accompanying the amended filing, "[T]he initial FAC/PPAC filing incorporated estimates based on the Company's estimated [Administrative and General (A&G) costs] for the 1998 budget which was initially compiled the last week of November. During the subsequent budget review process, adjustments and corrections were made to the initial A&G estimates and a more recent version of the Company budget was compiled the week ending December 5, 1997." On December 18, 1997, the Commission held a duly noticed consolidated hearing to review the Companies' FAC and PPAC rate filings. II. POSITIONS OF THE PARTIES AND STAFF A. The Companies Unitil presented calculations supporting CEC's request for a FAC credit of ($0.00246) per kWh and a PPAC rate of $0.00780 per kWh. The combined effect of the two rates is to increase a typical 500 kWh residential customer's bill by $0.43 per month, or 0.79%. Unitil also presented calculations in support of E&H's request for a FAC credit of ($0.00213) per kWh and a PPAC rate of $0.01074 per kWh. The combined effect of the two rates is to increase a typical 500 kWh residential customer's bill by $1.78 per month, or 3.38%. Unitil witness Sheryl L. Wookey, Contracts Manager for Unitil Service Corp., explained why a revised filing was made. The changes that were made in the revised filing lowered A&G costs from $1,631,100 to $1,356,000 for the demand charges and from $898,300 to $747,200 for the base energy charge. The unbilled prior amounts were respectively lowered from $781,500 to $749,300 and from $101,500 to $94,100. The effect was to reduce the demand charge from $26.64 per kW to $26.35 per kW, and to reduce the base energy charge from $0.00661 per kWh to $0.00632 per kWh. Ms. Wookey testified on the derivation of Unitil Power Corp's (UPC) wholesale rates and the calculation of UPC's short-term avoided costs. Her pre-filed testimony indicated that UPC's wholesale rates, effective January 1, 1998, would be as follows: Demand $26.35 per kW Base Energy $0.00632 per kWh Fuel Charge $0.02247 per kWh Ms. Wookey also discussed the approximate $3,000,000 in mitigation savings that Unitil had achieved. These savings can be attributed to the termination of contracts or portions thereof, buyouts of above market priced contracts, and other savings associated with the pass through of restructuring related savings under cost of service contracts. These savings represent almost 7% of retail power costs. Ms. Wookey also explained that the cause for higher replacement power costs were the result of a number of Unitil's suppliers being scheduled for either refueling or maintenance outages during the upcoming FAC/PPAC period. For example, during the month of April, four of its suppliers' units are scheduled for a combined total of 101 calendar days of outages. Linda S. Hafey, Supervisor of Regulatory Operations for Unitil Service Corp., explained that the difference in the rate increase between CEC and E&H can be directly attributable to the prior period over-collection of the purchased power costs. CEC's over-collection was $693,000, and E&H's was $109,000. The Companies also filed revised tariffs for short-term power purchase rates for Qualifying Facilities as follows: Energy Rates On Peak 3.78 cents per kWh Off Peak 2.82 cents per kWh All Hours 3.12 cents per kWh Capacity Rate $57.71 per kW-year B. Commission Staff Staff did not oppose the Companies' filings but conducted cross examination on 1) the mitigation savings achieved by the Companies, 2) the higher replacement power costs, 3) the impact, (both from the standpoint of capacity and the financial effect on a customer's bill), of the Millstone 3 unit being out, 4) the difference in the magnitude of the rate increase for each Company, 5) the errors in computing certain demand charges, and 6) the increase in the capacity rate for short-term power purchases for Qualifying Facilities. The capacity rate paid to QFs had been $6.34 per kW for the prior period. The Companies proposed a rate of $57.71 per kW. According to Ms. Wookey, this increase was due to two factors: 1) the capacity rating loss of the Millstone Units 1, 2 and 3 on November 1; and, 2) the uncertainty concerning the phase-in of a "capacity only" market in New England. This phase-in had originally been scheduled for November 1, 1997 but, in late October, it was postponed until April 1, 1998. Consequently, when Unitil had to purchase or arrange contracts for the period of time in which it was deficient in meeting its NEPOOL requirements, the price ranged from $5.75 to $6.75 per kW/month. Unitil has also changed its methodology of computing the weighted value of these costs. Instead of dividing the costs for the periods in which it was deficient by the total kW per month, including those months in which it had a surplus, the costs are now being divided only by the sum of the kW per month for those months in which a deficiency occurs. This results in the estimated costs being closer to actual since they are no longer being "diluted" by using the total kw for the whole period as the divider. Unitil also was questioned as to whether it was one of the plaintiffs to the Massachusetts lawsuit against NU regarding the Millstone outages. One of the wholly-owned subsidiaries of Unitil, Fitchburg Gas & Electric, is a joint owner of Millstone and is a party to the demand for arbitration in Connecticut and the Massachusetts lawsuit. With regards to the New Hampshire companies, Unitil has reached a settlement with NU for replacement energy associated with its entitlement in Millstone 3. UPC has since been able to withdraw from its entitlement in Millstone 3. III. COMMISSION ANALYSIS We have reviewed all the testimony and exhibits in this case, including the responses provided by the Companies. Based on our review of the record, we find that the FAC for the January 1 through June 30, 1998 period will be a credit of ($0.00246) per kWh for CEC and a credit of ($0.00213) per kWh for E&H. For the same period, the PPAC will be $0.0078 per kWh for CEC and $0.01074 per kWh for E&H. For a typical CEC residential customer using 500 kWh per month, the net result of the FAC and PPAC changes is a $0.43 increase to the monthly bill. For a typical E&H residential customer using 500 kWh per month, the net result of the FAC and PPAC changes is a $1.78 increase to the monthly bill. We find that the proposed short term avoided capacity and energy rates, although calculated in a somewhat different manner for this period than the methodology outlined in prior Commission orders, are just and reasonable. Based upon the foregoing, it is hereby ORDERED, that CEC's FAC rate for the period of January 1, 1998 through June 30, 1998, shall be a credit of ($0.00246) per kWh while its PPAC rate shall be $0.00780 per kWh; and it is FURTHER ORDERED, that E&H's FAC rate for the period of January 1, 1998 through June 30, 1998, shall be a credit of ($0.00213) per kWh while its PPAC rate shall be $0.01074 per kWh; and it is FURTHER ORDERED, that Concord Electric Company and Exeter & Hampton Electric Company file revised tariff pages in compliance with this order on or before January 31, 1998. By order of the Public Utilities Commission of New Hampshire this thirty-first day of December, 1997. Douglas L. Patch Bruce B. Ellsworth Susan S.
