Impact of the Restructuring of the Electric Power Industry on Oil, Gas, Coal, and Other Mineral Producers

Rocky Mountain Mineral Law Institute

The electric power industry is being restructured to give consumers access to competitively priced power. While transmission and distribution of electric power remain a natural monopoly, sufficient competition among the generation sector has developed. Accordingly, on March 4, 1997, the Federal Energy Regulatory Commission issued Order No. 8881 to restructure the wholesale power market to enable wholesale customers to realize the benefits of such competition.

Section 29 Credits - Appellate Practice: Telling the Right Story

Warren Gorham & Lamont's Journal of Taxation

The Section 29 credit provided a major incentive for the drilling of gas wells in search of qualified fuels- including gas produced from geopressured brine, tight formations, coal seams, and Devonian shale- before 1993.1 Even though more than three years have elapsed since that cutoff, a critical uncertainty persists concerning qualification for the credit, which is available with respect to the production and sale of qualified fuels through 2002. The source of the uncertainty is the requirement, set forth in Section 29(c)(2)(A), that the determination of whether gas is produced from geopressured brine, Devonian shale, coal seams, or a tight formation "shall be made in accordance with section 503 of the Natural Gas Policy Act of 1978" (NGPA).

Section 29 Credits Under A Cloud: Tax Court Renders Rev. Rul. 93-54 Meaningless

Warren Gorham & Lamont's Journal of Taxation

The court's questionable interpretation of a 1993 Ruling will be troublesome for taxpayers who relied on the implications of that Ruling to the effect that an NGPA well-category determination by FERC was not a prerequisite to the Section 29 credit for gas production. Although the Tax Court read the Ruling as assuming prior qualification, such qualification was clearly not possible under the circumstances. The Service's likely treatment of similarly situated taxpayers remains in doubt while the court's decision is being appealed to the Tenth Circuit.
