Analyst says gas industry unprepared to serve power demand
Investment banker Williams Capital Group LP, New York, says natural gas supply must rise a nearly 'preposterous' 50% to more than 33 tcf by 2004 to serve electric generation in development in the next 4 years. With 90% of a proposed 350,000 Mw of generating capacity scheduled to be gas-fired, unprecedented amounts of new net gas production will have to emerge in the next 3-5years, it said.

HOUSTON, June 29 -- Investment banker Williams Capital Group LP, New York, says natural gas supply must rise a nearly "preposterous" 50% to more than 33 tcf by 2004 to serve electric generation in development in the next 4 years.
With 90% of a proposed 350,000 Mw of generating capacity scheduled to be gas-fired, unprecedented amounts of new net gas production will have to emerge in the next 3-5 years or just 40-45% of these gas-fired plants will actually get built, said Christopher R. Ellinghaus, the firm's energy analyst.
Although independent power producers and other electricity suppliers hope to have 300,000 Mw of new generating capacity on line by 2005, it is doubtful that much more than 100,000 Mw will be possible over the next 3 years, Ellinghaus said.
He expects adequate gas supplies will be available to supply new plants built this year and in 2002, when 43,000 Mw and 36,000 Mw, respectively, are scheduled to come on line. But in subsequent years, he anticipates there will only be enough gas to support 20,000 Mw of new plant construction, even if supplies grow at 1-3%/year.
While gas prices have plummeted from $10/Mmbtu this winter to under $4 and storage injections are high, Ellinghaus said July will test peak supply capabilities. Fuel for new power plants for the next 2 years will actually come from the "destruction" of existing gas demand in the commercial and industrial sectors, he said.
Industrial demand destruction
But there are only so many "pizza parlor ovens" and other small users that can be shut down before getting into core use, Ellinghaus said. "We do not believe that demand destruction and modest net production growth will allow much more than the [power] plants under construction for commercial operation in 2001-2002 to be completed."
High demand certainly opens the door to LNG imports, which Ellinghaus predicted could grow to 750 bcf/year, enough to fuel about 15,000 Mw of generation. But even if industry "went crazy" over LNG, imports wouldn't be sufficient to serve the anticipated need, he said.
As a result, investor fretting over the potential for overbuilding, falling spark spreads, and lower spreads in the forward markets is overblown, Ellinghaus said. With gas prices of about $4/MMbtu, electric power prices of just under $50/Mw-hr will produce a "very strong" spark spread of about $25/Mw-hr for combined cycle generators, he said.
The firm's projections are based on electricity demand rising about 3%/year, somewhat higher than most forecasts. Demand has risen 3.1%/year for the last 5 years, except for 2000 when demand rose an estimated 3.5%.
If its analysis is correct, tight natural gas supplies should raise prices for gas and hence electricity production costs, regardless of price 'mitigation' efforts by regulators, Ellinghaus said. Regulatory meddling could delay new capacity additions and regulatory uncertainty could restrict financing for new capacity, the firm concluded.
While those new facilities that actually do get built will ease tight power markets and reduce political pressures to control prices in the near term, high gas prices and electricity price volatility are likely to continue. Only if new coal-fired or nuclear power plants come on line in significant numbers, Ellinghaus said, are shortages likely to be abated. Generators would have to build 200,000 Mw of generating capacity fueled by coal or uranium to meet long-term demand, he said.
However, because of the lengthy development cycle and public policy concerns, new plants relying on these energy sources will not begin to come on line in sufficient numbers until 2005 or 2006, Ellinghaus said, and waste disposal issues will continue to dog the nuclear industry.
