National Grid Transco (NYSE: NGG) is one of the largest utilities companies in the world. The company operates 4,300 miles of gas transmission pipelines, 93,800 miles of gas utilities infrastructure, and 71,000 circuit miles of electric utilities infrastructure. All of the company's operations are subject to rate regulations from the national governments of the United States and United Kingdom, as well as numerous U.S. state governments; this guarantees the company relatively steady income (averaged across its regulatory bodies, NGG's utilities companies earn a return on equity of 11%) but it also makes it difficult for National Grid to adjust when costs rise, as passing them on to consumers requires a lengthy lobbying process without the guarantee of success.

The Company owns electricity transmission networks in the United Kingdom and Wales, and operates the system across Great Britain. It also owns and operates high pressure gas transmission systems in the United Kingdom, and its distribution business delivers gas to 11 million homes and businesses. In the United States, National Grid delivers electricity to approximately 3.3 million customers in Massachusetts, New Hampshire, New York and Rhode Island, and manages the electricity network on Long Island. The Company is the distributor of natural gas in the northeastern United States, serving approximately 3.4 million customers in Massachusetts, New Hampshire, New York and Rhode Island.[1]

The company operates in 20 different regulatory regions, diluting the individual decisions of any one body in the company's larger revenue pool. National Grid is also looking to its aging infrastructure to spur earnings growth; as pipelines and cabling need to be replaced, the value of the company's assets will rise, bringing up the total value of the company's allowed returns with it. National Grid doesn't have any real competitors within its markets because the high cost of infrastructure for utilities companies means that the business creates natural, regional monopolies.

Company Overview

The non-regulated businesses in the United Kingdom are metering services, property management, the LNG importation terminal on the Isle of Grain, and the construction and operation of an electricity interconnector between The Netherlands and the United Kingdom through the BritNed joint venture. The non-regulated businesses in the United States include LNG storage, LNG road transportation, unregulated transmission pipelines, United States gas fields and home energy services.

Trends and Forces

Government Regulation of Gas Distribution Gives the Company Little Control over its Margins

Utilities are regulated businesses in both the U.S. and the UK. In the U.S., the national government sets regulations for transmissions while state governments set rules for distribution; in the UK, the national government regulates both. U.S. rates are set based on an allowed return on equity; across National Grid's U.S. operations, its average return on equity allowed is 11%. British regulations are different; rates are set, and then allowed to rise in five year cycles. For transmission, rates are allowed to rise at the rate of inflation plus 4.4% through 2012; electricity distribution sees rate increases of inflation plus 5.5% through 2010 and gas distribution sees rate increases of inflation plus 4.9% through 2013. The increases above inflation are allowed to support the company's need for capital investments. For example, the 4.4% increase for transmission is meant to support £4.4 billion in investments.[2]

These rules are designed to ensure both profitability for the company and accessibility for the consumer, but often hold back utilities companies, like National Grid, from achieving potential revenues and profitability by preventing them from charging delivery rates that the level of demand would allow. Regulation can also cause the company's margins to be volatile, as lobbying the government is the only way the company can control its prices. Unfortunately, natural gas costs fluctuate rapidly, but it takes a long time for NGG's lobbyists to convince state and regional regulators to raise the price ceiling. For the most part, regulators will only raise rates if the company can show that something, whether rising costs or inflationary pressure, is causing their margins to shrink to unfair levels; sometimes, they even decide to lower rates. Fortunately for National Grid, the company operates in twenty different regulatory environments, greatly reducing the overall effect of any one negative regulatory decision on the company's revenues.

Old Transmission Infrastructures in Both the U.S. and UK Need Replacing

Electric and gas distribution in both the U.S. and UK are beginning to age. Old, fraying wiring and rusting pipelines are risky; on April 15th 2008, for example, National Grid announced it would perform studies on its pipelines in New York City, after numerous leaks, fires, and explosions occurred the weekend before.[3] Bad infrastructure can lead to consumer deaths, bad publicity, and angry regulators, so National Grid has incentive to spend the large amounts of money needed to repair, expand, and replace them. Furthermore, the company's old capital has had years to depreciate, decreasing the value of its rate base, and of its equity; by replacing the pipelines and cabling, the company increases the value of both, and thus increases the amount of money it is allowed to earn.

The Credit Crunch Makes Accessing Funds for Capital Investment More Difficult

Transmissions pipelines and distribution infrastructure are both expensive endeavors for companies to undertake, which is why transmissions companies are parts of natural oligopolies and utilities are natural monopolies. National Grid Transco will need to make a number of new and upgraded installations, especially given the age of its capital and the early 2008 press over gas leaks and explosions. Such capital expenditures can cost billion of dollars, too much for the company to finance even with the rate increases allowed by the British government, so the company will need to turn to capital markets for funding. The credit crunch, however, as well as a worldwide recession means that lenders are less willing to hand their money out, making it more difficult for NGG to secure the funds needed to finance its investments at low interest rates.


High infrastructure costs make NGG a monopolist utility in the regions it services, though government regulation keeps the company from exploiting customers with high prices.
