Natural Gas

As U.S. policymakers consider how to tackle the challenge of greenhouse-gas constraints, the U.K.’s approach to the problem offers instructive examples.

A lengthy letter to the editor addresses whether the Energy Information Administration’s gas-market forecasts, as laid out in a recent article, are biased. The authors of the original piece, Timothy J. Considine and Frank A. Clemente, then respond to the letter.

In January 2004, FERC authorized AES Ocean Express LLC (AES) to construct and operate natural-gas pipeline facilities to transport revaporized LNG from an offshore receipt point at the boundary between the Exclusive Economic Zone of the United States and the Commonwealth of the Bahamas to onshore delivery points on the east coast of Florida. AES proposed to connect its planned pipeline to the pipeline system of Florida Gas Transmission (FGT). AES and FGT were unable to agree upon the terms and conditions to be included in FGT’s tariff regarding the LNG delivered through AES’ proposed pipeline, leading to AES filing a formal complaint with FERC, wherein it alleged that FGT sought to impose unreasonably restrictive gas quality and interchangeability standards on LNG delivered into the FGT system.

Natural-gas estimates from the Energy Information Administration (EIA) are supposed to be “policy neutral.” Are they? Over the past decade, EIA forecasts for NG differ substantially from actual outcomes—even though overestimations of supply capabilities could lead to underestimating the costs of carbon regulations.

The answer to the question of who will be responsible for cost-mitigation measures to accommodate the introduction of large quantities of LNG into the U.S. pipeline grid remains up in the air for now, but there are signs pointing in one particular direction: toward ratepayers.

John S. Ferguson: I concur with Mark Williams’ assessment that the proposed KKR/TPG acquisition of TXU through a leveraged buyout (LBO) may “have negative consequences for Texas customers,” which he indicates as being a consequence of the nature of an LBO. I think it is more likely a consequence of the nature of the restructuring imposed by the Texas Legislature.

Stephen L. Teichler and Ilia Levitine: We take it with good humor that Scott Strauss and Jeffrey Schwartz used our report on the 9th Circuit’s recent Mobile-Sierra decisions as a foil to the grand argument that courts should return to the “statutory roots” in their interpretation of Mobile-Sierra.

Retaining adequate earnings is the driving motive for revenue decoupling (RD) among gas utilities, while conservationists view RD as necessary for the removal of resistance to energy efficiency. But the benefits of RD to consumers are less certain.

To better understand the evolving outlook for LNG and its role in the U.S. gas market, Fortnightly assembled a group of LNG specialists with various perspectives on the issues.

While oil and gas prices now are falling after the latest experience with fuel-price volatility, the Global Energy Decision fuels team is focused on modeling an integrated world-wide system of fuel relationships encompassing crude oil, natural gas, coal, and increasingly, synfuels to help our clients assess the implications of fuel-price swings on their businesses. Let’s look at the potential impacts and implications of this growing reliance on liquefied natural gas for North America’s power-generation demand.

An analysis of what risks must be taken, in the short run, to significantly reduce carbon emissions with use of natural gas.
