Principal activities

We are one of the leading electricity distribution service providers in the northeastern US, as measured by energy delivered, and one of the largest utilities in the US, as measured by the number of electricity distribution customers. US electricity and gas distribution serves approximately 3.4 million electricity customers over a network of 72,000 circuit miles in New England and New York and around 569,000 gas customers over a pipeline of 8,600 miles in New York.

External and regulatory environment

In the US, our electricity system spans upstate New York, Massachusetts, Rhode Island and New Hampshire to customers that include residences and small and large commercial and industrial enterprises. Our gas distribution system serves customers in cities and towns in central and eastern New York. Sharp increases in energy prices have renewed interest in the public policy debate about restructuring the nation’s electricity industry and increased the pressure on regulators and politicians to consider taking action to mitigate the effects of increased prices on customers.

As the debate continues, we have taken a leadership position, by advocating that a well-managed electricity system is the key to enabling robust competitive electricity markets that offer customers choice, savings and other benefits. State regulators continue to strongly support current recovery of power supply costs.

Our regulated operations and certain unregulated businesses must comply with rules prescribed by the applicable state utility commissions of New York, Massachusetts, Rhode Island and New Hampshire as well as the rules prescribed by the Federal Energy Regulatory Commission. Certain regulated operations were also subject to regulation by the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 until its repeal became effective on 8 February 2006.

Our New York business files reports with the Securities and Exchange Commission under its legal name, Niagara Mohawk Power Corporation.

Business drivers

Our primary business drivers are the long-term rate plans with state regulators through which we can earn and retain certain amounts in excess of traditional regulatory allowed returns. These plans provide incentive returns and shared savings allowances, which allow us an opportunity to benefit from efficiency gains we may identify within our operations.

Our other main business drivers for US electricity and gas distribution include our ability to streamline operations, to enhance reliability and to generate funds for investment in our infrastructure.

We recover our costs of providing electricity and gas distribution under rates approved by applicable regulators. The rates are set based on historical or forecasted costs, and we earn a return on our assets. We benefit from the savings associated with identifying additional efficiencies. Commodity costs are passed through to customers. We are also subject to service quality standards with respect to reliability and certain aspects of customer service and safety.

We work towards service quality standards that our state regulators expect us to achieve. If we fall below a prescribed standard, we may incur a penalty. If we do better than the standard, we may in some cases achieve an incentive.

   
New York

Our electricity delivery rates are governed by a ten-year rate plan that began on 1 February 2002. Under the plan, after reflecting our share of savings related to the acquisition of our New York business, we may earn a threshold return on equity for our electricity distribution business of 10.6%, or 12.0% if certain customer outreach, education, competition-related and low income incentive targets are met, and half of any earnings in excess of that amount up to 14%, 25% of any earnings in excess of that up to 16% and 10% beyond that.

This effectively offers us the potential to achieve a return in excess of the regulatory allowed return of 10.6%.

Under the plan, gas delivery rates were frozen until the end of the 2004 calendar year, and we now have the right to request an increase at any time, if needed. We may earn a threshold return on equity ranging from 10.6% to 12.6% depending on the achievement of certain customer migration levels and customer awareness and understanding of gas competitive opportunities. Above this threshold, the revenue equivalent of gas earnings must be shared equally between shareholders and customers.

Massachusetts

Under our long-term rate plan in Massachusetts, which runs until 2020, there is no cap on earnings and no earnings-sharing mechanism until 2010. From May 2000 until February 2005, rates were frozen. In March 2005, a settlement credit in the company’s rates expired, which represents an increase of £6 million in pre-tax income through to February 2006.

From March 2006, rates are adjusted each March until 2009 by the annual percentage change in average electricity distribution rates in the northeastern US. Regulators approved the first such annual increase in the amount of £11 million, effective 1 March 2006. In 2009, actual earned savings will be determined and we will be allowed to retain 100% of annual earned savings up to £39 million and 50% of annual earned savings between £39 million and £81 million before tax. Earned savings represent the difference between a test year’s distribution revenue and our cost of providing service during the same test year, including a regional average authorised return.

These efficiency incentive mechanisms provide an opportunity to achieve returns in excess of traditional regulatory allowed returns. We will be allowed to include our share of earned savings in demonstrating our costs of providing service to customers from January 2010 until May 2020.

Rhode Island

Our distribution rates in Rhode Island are also governed by a long-term rate plan. Between May 2000 and the end of October 2004, rates were frozen, and we were permitted to retain 100% of our Rhode Island earnings up to an allowed return on equity of 12%. We kept 50% of earnings between 12% and 13%, and 25% of earnings in excess of 13%. With effect from November 2004 until December 2009, we agreed to lower our rates by £6 million before tax per year.

From January 2005 onwards we are able to keep an amount equal to 100% of our earnings up to an allowed return on equity of 10.5%, plus £2.6 million before tax, which represents our share of demonstrated savings subsequent to the acquisition of Eastern Utilities Associates in 2000. Earnings above that amount up to an additional 1% return on equity are to be shared equally with our customers, while additional earnings will be allocated 75% to customers and 25% to us. This regulatory mechanism offers the potential to achieve returns in excess of traditional regulatory allowed returns.

New Hampshire

Our distribution rates in New Hampshire are based on our costs of providing distribution service plus a return on our investment, predominantly in the distribution system infrastructure. These rates are authorised by the New Hampshire Public Utilities Commission.

 

Objectives and strategy

Our objective is to be the premier US energy delivery company through innovation and continuous improvement in safety, service quality and efficiency, and by operating in an environmentally and ethically responsible manner, to the benefit of customers, shareholders and employees alike.

Meeting or exceeding our regulated service quality goals is a main objective. We aim to realise this objective by increasing customer satisfaction through a focus on improving service quality as we strive for the optimum performance, and implementing a reliability enhancement programme to improve service to our customers. A significant increase in spending on our infrastructure is under way in order to modernise it to attain service quality goals.

Our approach to working towards our safety and occupational health objective is to cultivate a culture in which acting safely becomes second nature. Zero injuries every day for both our employees and the people within our service territories is our goal and we believe this is achievable and sustainable. We will continue to collaborate with regulators, policy makers and customers to advance the development of the competitive electricity and natural gas marketplace.

In line with our reliability objective, in order to improve performance we have developed and begun execution of a fiveyear reliability enhancement programme. This is made up of four main categories of work:

  • vegetation management – incremental tree trimming to address an increase in customer interruptions related to contacts with tree limbs;
  • feeder hardening – upgrading our worst-performing overhead electric circuits by replacing aged and deteriorated components and protecting against lightning strikes and animal contacts;
  • asset replacement – replacing aging distribution equipment before its expected end of life, including poles, underground cable and substation equipment; and
  • inspection and maintenance – increasing our preventive maintenance and repair activities to find potential faults before they occur.

The planned capital investment of £290 million over the next five years from these initiatives will be recovered from customers in accordance with our rate plans. The remaining incremental operating costs will be offset by efficiencies created within our business.

Our workforce recruitment objective is to become the employer of choice. We seek to source and hire the best and the brightest to create a workplace as diverse as the population we serve. Our strategy is to expand conventional sourcing strategies, such as educational partnerships, and offer challenging career opportunities and succession plans to retain our valued employees.

We are committed to creating a climate that values, respects, appreciates and celebrates the unique differences of all employees, stakeholders and customers. The objective is to be a company that better reflects our customer base and is recognised for our inclusion and diversity efforts by our employees, peers and the communities we serve.
