Commitments And Contingencies [Abstract] |
Commitments And Contingencies | Note 5: Commitments and Contingencies Regulatory Matters Overview (Unitil Energy, Fitchburg, and Northern Utilities)—Unitil's distribution utilities deliver electricity and/or natural gas to customers in the Company's service territories at rates established under traditional cost of service regulation. Under this regulatory structure, Unitil Energy, Fitchburg, and Northern Utilities recover the cost of providing distribution service to their customers based on a representative test year, in addition to earning a return on their capital investment in utility assets. As a result of the restructuring of the utility industry in New Hampshire, Massachusetts and Maine, most Unitil customers have the opportunity to purchase their electric or natural gas supplies from third-party suppliers. For Northern Utilities, only business customers have the opportunity to purchase their natural gas supplies from third-party suppliers at this time. Most small and medium-sized customers, however, continue to purchase such supplies through Unitil Energy, Fitchburg and Northern Utilities as the providers of basic or default service energy supply. Unitil Energy, Fitchburg and Northern Utilities purchase electricity or natural gas for basic or default service from unaffiliated wholesale suppliers and recover the actual costs of these supplies, without profit or markup, through reconciling, pass-through rate mechanisms that are periodically adjusted. In connection with the implementation of retail choice, Unitil Power, which formerly functioned as the wholesale power supply provider for Unitil Energy, and Fitchburg divested their long-term power supply contracts through the sale of the entitlements to the electricity sold under those contracts. Unitil Energy and Fitchburg recover in their rates all the costs associated with the divestiture of their power supply portfolios and have secured regulatory approval from the NHPUC and MDPU, respectively, for the recovery of power supply-related stranded costs and other restructuring-related regulatory assets. The remaining balance of these assets, to be recovered principally over the next one to three years, is $34.7 million as of December 31, 2011 including $12.4 million recorded in Current Assets as Accrued Revenue on the Company's Consolidated Balance Sheet. Unitil's distribution companies have a continuing obligation to submit filings in both states that demonstrate their compliance with regulatory mandates and provide for timely recovery of costs in accordance with their approved restructuring plans. Fitchburg—Increase in Base Rates Approved—On August 1, 2011, the MDPU issued and order approving increases of $3.3 million and $3.7 million in annual distribution revenues for Fitchburg's electric and gas divisions, respectively. The MDPU also approved revenue decoupling mechanisms and a return on equity of 9.2% for both the electric and gas divisions of Fitchburg. The rate increase for Fitchburg's electric division included the recovery of $11.4 million of previously deferred emergency storm restoration costs associated with the December 2008 ice storm, which costs are to be amortized and recovered over seven (7) years without carrying costs. The order provides resolution to the open regulatory matters concerning the ratemaking treatment and cost recovery related to the December 2008 ice storm event. Granite State—Increase in Base Rates Approved—On January 31, 2011, the FERC approved a settlement agreement providing for an increase of $1.7 million in annual revenue, based on new gas transportation rates to be effective January 1, 2011. Subsequently, on August 31, 2011, the FERC approved an amendment to the settlement agreement which provides for an additional increase of approximately $0.5 million in Granite State's annual revenues effective August 1, 2011. Under the amended settlement agreement, beginning in 2012, Granite State is permitted to file limited annual rate adjustment filings to recover the revenue requirements for certain specified future capital cost additions to transmission plant projects. The limited rate adjustments would be effective August 1 of each year, and are projected to conclude in 2014 when the major projects will be completed. The annual revenue increases for the limited rate adjustments are estimated to be approximately $0.5 million each year during 2012 through 2014. Unitil Energy—Increase in Base Rates Approved—On April 26, 2011, the NHPUC approved a final rate settlement which makes permanent a temporary increase of $5.2 million in annual revenue effective July 1, 2010, and provides for an additional increase of $5.0 million in annual revenue effective May 1, 2011. The settlement extends through May 1, 2016 and provides for a long-term rate plan and earnings sharing mechanism, with estimated future increases of $1.5 million to $2.0 million in annual revenue to occur on May 1, 2012, May 1, 2013 and May 1, 2014, to support Unitil Energy's continued capital improvements to its distribution system. The rate plan allows Unitil to file for additional rate relief if its return on equity is less than 7% and a sharing of earnings with customers if its return on equity is greater than 10% in a calendar year. The settlement provides for a return on equity of 9.67%, a common equity ratio of 45.45% and an overall weighted cost of capital of 8.39% to determine changes to distribution rate levels. The settlement approved Unitil Energy's proposal for an augmented vegetation management program and reliability enhancement program. Under the augmented vegetation management program, Unitil Energy will be increasing its vegetation management spending from a test-year spending level of approximately $0.7 million to $3.1 million per year by 2013. Under the new reliability enhancement program, Unitil Energy will spend $1.8 million annually towards targeted projects designed to enhance system reliability. The funding for both of these programs is included in the future rate increases discussed above. The settlement provides for recovery of deferred December 2008 ice storm and February 2010 wind storm costs of approximately $7.6 million, including carrying charges. These costs will be recovered over eight years in the form of a tariff surcharge. Finally, the settlement establishes a major storm reserve of $400,000 annually, which will be used to recover costs associated with responding to and recovering from future qualifying major storm events. Northern Utilities—Base Rate Case Filings—In May 2011, Northern Utilities filed two separate rate cases with the NHPUC and MPUC requesting approval to increase its natural gas distribution base rates in New Hampshire and Maine, respectively. On November 29, 2011, the MPUC approved a comprehensive settlement agreement providing for a $7.8 million permanent increase in annual distribution revenue for Northern Utilities' Maine operations, effective January 1, 2012, and an additional permanent increase in annual distribution revenue of $0.85 million to recover the costs of 2011 cast iron pipe replacement capital spending effective May 1, 2012. The settlement is inclusive of an earlier settlement for a temporary rate increase of $3.5 million in annual distribution revenue effective November 1, 2011. The settlement also precludes Northern Utilities from filing for a new base rate increase with an effective date prior to January 1, 2014. In New Hampshire, Northern Utilities requested an increase of $5.2 million in annual gas distribution base revenue, which represents an increase of approximately 8.1%. On July 22, 2011, the NHPUC approved a settlement for a temporary rate increase of approximately $1.7 million in annual revenue effective August 1, 2011. Once permanent rates are approved by the NHPUC, they will be reconciled back to August 1, 2011. The Company is currently in settlement discussions with the NHPUC and a final rate order is expected in the first quarter of 2012. Fitchburg—Management Audit—As a result of its investigation of Fitchburg's preparation for, and response to, the December 2008 ice storm, the MDPU ordered a comprehensive independent management audit of Fitchburg's management practices. The management audit, which was performed by Jacobs Consultancy, Inc. (Jacobs), was completed and the audit report was submitted by Jacobs to the MDPU on April 13, 2011. The audit report found Unitil's management practices to be comprehensive, sound and in-line with industry practice. It also included sixteen recommendations intended to further improve the results of Unitil's management strategy, and acknowledged that many of these recommendations were already being implemented by the Company. On September 1, 2011, the MDPU issued its order with respect to the audit, accepting the majority of Jacob's audit report, and requiring the company to implement the remaining recommendations, as well as provide semi-annual status updates as to the company's implementation progress. On September 30, 2011, the Company filed its first implementation status report with the MDPU. Fitchburg—Electric Operations—On November 30, 2011, Fitchburg submitted its annual reconciliation of costs and revenues for Transition and Transmission under its restructuring plan. The filing includes the reconciliation of costs and revenues for a number of surcharges and cost factors which are under individual review in separate proceedings before the MDPU, including the Pension/PBOP Adjustment, Residential Assistance Adjustment Factor, Net Metering Recovery Surcharge, Attorney General Consultant Expense Factor and Revenue Decoupling Adjustment Factor. The rates were approved effective January 1, 2012, subject to reconciliation pending investigation by the MDPU. This matter remains pending. Final orders on Fitchburg's 2009 and 2010 annual reconciliation filings also remain pending. Fitchburg—Gas Operations—On November 2, 2011, the SJC issued its decision vacating an order issued on November 2, 2009 by the MDPU in which the MDPU ordered Fitchburg to refund $4.6 million of natural gas costs, plus interest. The MDPU's original order issued in 2009 found that the Company had engaged in certain price stabilization practices for the 2007 / 2008 and 2008 / 2009 heating seasons without the MDPU's prior approval and that the Company's natural gas purchasing practices were imprudent. The Company appealed the MDPU's decision to the SJC. The SJC's decision vacates the MDPU's order to refund $4.6 million, plus interest, in favor of a $0.2 million refund, plus interest. The Company had previously recorded a pre-tax charge to earnings and recognized a Regulatory Liability of $4.9 million in the fourth quarter of 2009 based on the MDPU's original order. As a result of the decision, the Regulatory Liability was adjusted and the Company recognized a credit of $4.7 million in the fourth quarter of 2011. On December 28, 2011, the MDPU approved Fitchburg's proposal to discontinue the previously ordered refund of the $4.6 million of natural gas costs, and to begin the recoupment of the amounts previously refunded, with interest, effective January 1, 2012. In order to minimize the rate impact on customers, the recoupment will occur over the next three winter heating seasons. Fitchburg—Storm Cost Deferral Petition—On December 16, 2011, Fitchburg filed a request with the MDPU for authorization to defer, for future recovery in rates, the costs incurred to perform storm-related emergency repairs on its electric distribution system as a result of two recent storms, Tropical Storm Irene, which occurred on August 28, 2011, and a severe snow storm, which occurred on October 29-30, 2011. Fitchburg estimates that it incurred $1.5 million in costs for Tropical Storm Irene and $3.2 million in costs for the October snow storm. Fitchburg also requested that it be allowed to accrue carrying charges on the deferred amount. This matter remains pending. Fitchburg—Other—On February 11, 2009, the Massachusetts Supreme Judicial Court (SJC) issued its decision in the Attorney General's (AG) appeal of the MDPU orders relating to Fitchburg's recovery of bad debt expense. The SJC agreed with the AG that the MDPU was required to hold hearings regarding changes in Fitchburg's tariff and rates, and on that basis vacated the MDPU orders. The SJC, however, declined to rule on an appropriate remedy, and remanded the cases back to the MDPU for consideration of that issue. In the Company's August 1, 2011 rate decision the MDPU held that the approval of dollar for dollar collection of supply-related bad debt in the Company's rate cases in 2006 (gas) and 2007 (electric) satisfied the requirement for a hearing ordered by the SJC. The matter of how to address the amounts collected by Fitchburg between the time the MDPU first approved dollar for dollar collection of the Company's bad debt, and the rate decisions in 2006 and 2007, remains pending before the MDPU. On July 2, 2008, the Governor of Massachusetts signed into law "The Green Communities Act" (the GC Act), an energy policy statute designed to substantially increase energy efficiency and the development of renewable energy resources in Massachusetts. The GC Act provides for utilities to recover in rates the incremental costs associated with its various mandated programs. Several regulatory proceedings have been initiated to implement various provisions of the GC Act, including provisions for each distribution company to file enhanced three-year energy efficiency investment plans, plans to establish smart grid pilot programs, proposals to purchase long-term contracts for renewable energy, special tariffs to allow the net metering of customer-owned renewable generation, and terms and conditions for purchasing supplier receivables. Fitchburg's three year energy efficiency investment plans, plans to establish smart grid pilot programs, net metering tariffs and proposals to purchase long-term contracts for renewable energy have been approved by the MDPU. Terms and conditions for purchasing supplier receivables are under review in a separately designated docket. On March 1, 2011, Fitchburg submitted its 2010 Service Quality Reports for both its gas and electric divisions. Fitchburg reported that it met or exceeded its benchmarks for service quality performance in all metrics for both its gas and electric divisions. On January 13, 2012, the MDPU issued its order approving the 2010 Service Quality Report for Fitchburg's gas division. On January 26, 2011, the MDPU issued orders with respect to Fitchburg's 2008 and 2009 Service Quality Reports for its electric division. Fitchburg failed to meet certain of its service quality benchmarks in 2008, and a penalty of $100,478 was ordered to be refunded to its electric customers. The Company refunded this amount to customers in their June and July 2011 billings. For 2009 performance, no net penalty was assessed. As required by the order, on February 16, 2011 Fitchburg filed a report regarding the actions it has taken to improve its performance in the metrics it had not met. Unitil Energy—Annual Rate Reconciliation Filing—On July 29, 2011, the NHPUC approved Unitil Energy's annual reconciliation and rate filing under its restructuring plan, for rates effective August 1, 2011, including reconciliation of prior year costs and revenues. Unitil Energy—Billing—In August 2011, Unitil Energy and one of its larger customers in New Hampshire settled a lawsuit filed by the customer in June 2011 regarding a billing error that resulted from a transformer connected to the customer's meter, which had been mislabeled by the manufacturer, and caused Unitil Energy to overcharge the customer for bills issued from October 2004 through January 2011. The amount of the customer's overpayment was calculated to be $1.8 million (Distribution and Other Delivery Charges—$0.5 million; Supply Charges—$1.3 million). As a result of the settlement, Unitil Energy reimbursed the customer $1.8 million plus $0.3 million of interest. The Company recognized a non-recurring charge of $0.4 million for distribution charges plus interest in 2011. As a result of this metering issue, which was discovered in February 2011, certain other customers in the Company's service territory were under-billed from October 2004 through January 2011 for supply charges. Accordingly, the Company has requested authorization from the NHPUC to process the billing correction. The Company's request remains pending before the NHPUC. Northern Utilities—NOPV—On November 21, 2008, the MPUC issued an order approving a settlement agreement resolving a number of Notices of Probable Violation (NOPVs) of certain safety related procedures and rules by Northern Utilities. Under the Settlement, Northern Utilities will incur total expenditures of approximately $3.8 million for safety related improvements to Northern Utilities' distribution system to ensure compliance with the relevant state and federal gas safety laws, for which no rate recovery will be allowed. These compliance costs were accrued by Northern Utilities prior to the acquisition date and the remaining amount on the Company's consolidated balance sheet at December 31, 2011 was $0.8 million. Northern Utilities—Cast Iron Pipe Replacement Program—On July 30, 2010, the MPUC approved a Settlement Agreement providing for an accelerated replacement program for cast iron distribution pipe remaining in portions of Northern Utilities' Maine service areas. Under the Agreement, Northern Utilities will proceed with a comprehensive upgrade and replacement program (the Program), which will provide for the systematic replacement of cast iron, wrought iron and bare steel pipe in Northern Utilities' natural gas distribution system in Portland and Westbrook, Maine and the conversion of the system to intermediate pressure. The Agreement establishes the objective of completing the Program by the end of the 2024 construction season. Northern Utilities—Maine Sales Tax Under-Collection—As previously reported, during 2011 the Company determined that during the conversion of the Northern Utilities customer portfolio from the prior owner to Unitil's customer information system, a portion of Northern Utilities' commercial and industrial customers were incorrectly converted as exempt from Maine sales tax. This issue has been resolved with Maine Revenue Services and the MPUC and the Company has collected substantially all of the arrears. Unitil Corporation—FERC Audit—On November 3, 2011, the FERC commenced an audit of Unitil Corporation, including its associated service company and its electric and natural gas distribution companies. Among other requirements, the audit will evaluate the Company's compliance with: i) cross-subsidization restrictions on affiliate transactions; ii) regulations under the Energy Policy Act of 2005; and the iii) uniform system of accounts for centralized service companies. The Company expects the final audit report will be issued by December 31, 2012. Legal Proceedings The Company is involved in legal and administrative proceedings and claims of various types, which arise in the ordinary course of business. The Company believes, based upon information furnished by counsel and others, that the ultimate resolution of these claims will not have a material impact on the Company's financial position. A putative class action complaint was filed against Fitchburg on January 7, 2009 in Worcester Superior Court in Worcester, Massachusetts, captioned Bellerman v. Fitchburg Gas and Electric Light Company. On April 1, 2009, an Amended Complaint was filed in Worcester Superior Court and served on Fitchburg. The Amended Complaint seeks an unspecified amount of damages, including the cost of temporary housing and alternative fuel sources, emotional and physical pain and suffering and property damages allegedly incurred by customers in connection with the loss of electric service during the ice storm in Fitchburg's service territory in December, 2008. The Amended Complaint includes M.G.L. ch. 93A claims for purported unfair and deceptive trade practices related to the December 2008 ice storm. On September 4, 2009, the Superior Court issued its order on the Company's Motion to Dismiss the Complaint, granting it in part and denying it in part. The Company anticipates that the court will decide whether the lawsuit is appropriate for class action treatment in late 2012. The Company continues to believe the suit is without merit and will defend itself vigorously. On November 2, 2011, the Massachusetts Supreme Judicial Court (SJC) issued its decision vacating an order issued on November 2, 2009 by the MDPU in which the MDPU ordered Fitchburg to refund $4.6 million of natural gas costs, plus interest. The MDPU's original order issued in 2009 found that the Company had engaged in certain price stabilization practices for the 2007 / 2008 and 2008 / 2009 heating seasons without the MDPU's prior approval and that the Company's natural gas purchasing practices were imprudent. The Company appealed the MDPU's decision to the SJC. The SJC's decision vacates the MDPU's order to refund $4.6 million, plus interest, in favor of a $0.2 million refund, plus interest. See additional discussion above in Regulatory Matters. Environmental Matters The Company's past and present operations include activities that are generally subject to extensive and complex federal and state environmental laws and regulations. The Company believes it is in compliance with applicable environmental and safety laws and regulations, and the Company believes that as of December 31, 2011, there were no material losses reasonably likely to be incurred in excess of recorded amounts. However, there can be no assurance that significant costs and liabilities will not be incurred in the future. It is possible that other developments, such as increasingly stringent federal, state or local environmental laws and regulations, could result in increased environmental compliance costs. Fitchburg's Manufactured Gas Plant Site—Fitchburg continues to work with environmental regulatory agencies to identify and assess environmental issues at the former manufactured gas plant (MGP) site at Sawyer Passway, located in Fitchburg, Massachusetts. Fitchburg has proceeded with site remediation work as specified on the Tier 1B permit issued by the Massachusetts Department of Environmental Protection, which allows Fitchburg to work towards temporary closure of the site. A status of temporary closure requires Fitchburg to monitor the site until a feasible permanent remediation alternative can be developed and completed. Fitchburg recovers the environmental response costs incurred at this former MGP site in gas rates pursuant to the terms of a cost recovery agreement approved by the MDPU. Pursuant to this agreement, Fitchburg is authorized to amortize and recover environmental response costs from gas customers over succeeding seven-year periods, without carrying costs. Fitchburg had filed suit against several of its former insurance carriers seeking coverage for past and future environmental response costs at the site. In January 2011, Fitchburg settled with the remaining insurance carriers for approximately $2.0 million and received these payments in the first quarter of 2011. Any recovery that Fitchburg receives from insurance or third-parties with respect to environmental response costs, net of the unrecovered costs associated therewith, are shared equally between Fitchburg and its gas customers. Fitchburg is in the process of developing long-range plans for a feasible permanent remediation solution for the Sawyer Passway site, including alternatives for re-use of the site. Included on the Company's Consolidated Balance Sheets at December 31, 2011 and 2010 in Environmental Obligations are accrued liabilities totaling $12.0 million and $12.0 million, respectively, related to estimated future clean-up costs for permanent remediation of the Sawyer Passway site. A corresponding Regulatory Asset was recorded to reflect that the recovery of this environmental remediation cost is probable through the regulatory process. The amounts recorded do not assume any amounts are recoverable from insurance companies or other third-parties. Northern Utilities Manufactured Gas Plant Sites—Northern Utilities has an extensive program to identify, investigate and remediate former MGP sites that were operated from the mid-1800s through the mid-1900s. In New Hampshire, MGP sites were identified in Dover, Exeter, Portsmouth, Rochester and Somersworth. This program has also documented the presence of MGP sites in Lewiston and Portland, Maine and a former MGP disposal site in Scarborough, Maine. Northern Utilities has worked with the environmental regulatory agencies in both New Hampshire and Maine to address environmental concerns with these sites. Northern Utilities or others have substantially completed remediation of the Exeter, Rochester, Somersworth, Portsmouth, and Scarborough sites. The sites in Lewiston and Portland have been investigated and remedial activities are currently underway. Future operation, maintenance and remedial costs have been accrued, although there will be uncertainty regarding future costs until all remedial activities are completed. The NHPUC and MPUC have approved the recovery of MGP environmental costs. For Northern Utilities' New Hampshire division, the NHPUC approved the recovery of MGP environmental costs over a seven-year amortization period. For Northern Utilities' Maine division, the MPUC authorized the recovery of environmental remediation costs over a rolling five-year amortization schedule. Included in the Company's Consolidated Balance Sheets at December 31, 2011 and 2010 are current and non-current accrued liabilities totaling $2.7 million and $2.6 million, respectively, associated with Northern Utilities environmental remediation obligations for these former MGP sites. A corresponding Regulatory Asset was recorded to reflect that the recovery of these environmental remediation cost is probable through the regulatory process. The Company's ultimate liability for future environmental remediation costs, including MGP site costs, may vary from estimates, which may be adjusted as new information or future developments become available. Based on the Company's current assessment of its environmental responsibilities, existing legal requirements and regulatory policies, the Company does not believe that these environmental costs will have a material adverse effect on the Company's consolidated financial position or results of operations. The following table shows the balances and activity in the Company's liability for Environmental Obligations for 2011 and 2010. ENVIRONMENTAL OBLIGATIONS
