at CERAweek, most life was carbon-based

April 2007 for Power Magazine

Daniel Yergin, founder and CEO of Cambridge Energy Associates (CERA), is among the best at connecting the dots of the energy industry's past and turning them into a coherent picture of its future. Dr. Yergin's accomplishments include a Pulitzer Prize for The Prize: The Epic Quest for Oil, Money & Power, a book that was made into an eight-hour PBS documentary. When Yergin talks, people listen.

The theme that Yergin chose for CERA Week 2007 in Houston this February—"Strategies for a High Stakes World: Innovation, Investment, and the Future of Energy"—correctly cast today's energy business as a game with big financial risks and rewards. High and volatile gas and gasoline prices, concerns about global warming and the long-term adequacy and security of energy supplies, and the behind-the-scenes geopolitical maneuverings that shape today global energy environment have become front-page news.

The first two days of the conference were devoted to worldwide oil and gas supply and demand. The third day—Power Day, the one of most interest to readers of this magazine—began with a panel of utility CEOs discussing "The Next Big Ideas" for the electricity industry.

Seven steps to heaven

Jeff Sterba—CEO of PNM Resources (the parent of Public Service Co. of New Mexico), and chairman of EPRI as well—kicked off the discussion with a presentation titled, "Technology Needs for a Carbon Constrained World." He reminded the audience that, as of the end of 2006, the U.S. electric utility sector was responsible for roughly one-third of America's emissions of carbon dioxide (CO2), or about 2,400 million metric tons (mt) annually (Figure 1). If no action is taken to curb them, the sector's emissions are projected to increase to 3,300 million mt/year by 2030.

It will be challenging enough to hold CO2 emissions at today's levels, much less reduce them. Assuming, as the projections do, that advanced carbon capture and sequestration technologies (see Special Reports) will not be ready or affordable enough to be part of a nationwide solution for many years, it's clear that the only near-term way to decelerate climate change is to deploy proven technologies.

Sterba described a step-by-step approach for halving the 3,300 million tons expected under the "do nothing" scenario to 1,700 million tons by 2030:

  • Increase the efficiency of appliances and lighting to reduce annual demand growth from the current 1.5% to 1%. This step alone would reduce CO2 emissions 9% by 2030.
  • Build 50 GW of wind farms and solar power plants by 2020, and an additional 2 GW/year thereafter.
  • Add 24 GW of nuclear capacity by 2020, and another 4 GW/year thereafter.
  • Target raising the efficiency of new coal-fired plants to 46% by 2020 and to 49% by 2030.
  • Make 90% of the new coal plants carbon capture ready by 2020.
  • Strive to have electric cars constitute 10% of all U.S. vehicles by 2017, and 30% by 2027.
  • Increase distributed generation's share of U.S. installed capacity from less than 0.1% today to 5% by 2030.

Sterba's concluding remarks were directed to the U.S. Congress. He urged the House and Senate to join forces and pass legislation that would impose a tax on electricity consumption and thereby curb demand and power plants' overall CO2 emissions. The rate, said Sterba, should be high enough to provide $2 billion to $3 billion per year for research into carbon-constrained generation technologies.

Use the plug, not the pump

The next speaker, Thiery Vandal, CEO of Hydro Qubec (HQ), stood apart from the other utility panelists in that his province is blessed with and relies heavily on hydro power. He explained that HQ invests more than $100 million annually to research and develop new hydro turbine and transmission technologies.

Vandal explained that there is a way for global warming's two main causes—coal-fired plants and petroleum consumption by cars and trucks (Figure 2)—to work in concert to reduce each other's negative impact. He praised plug-in hybrid cars as the single best idea for achieving large reductions in CO2 from the transportation sector. Several car makers agree, and they are preparing to introduce vehicles with that capability over the next few years.

Doing well by doing good

A third speaker on the opening panel of CERA Week 2007's Power Day was just as enthusiastic about plug-in hybrids, but he also saw the scheme as an opportunity to expand power markets. Indeed, David Crane—CEO of NRG Energy Inc.—boldly declared that utilities have "A Moral Imperative to Act" to reduce their greenhouse gas emissions.

Crane explained that utilities would have to generate 33% more kilowatt-hours annually if the 240 million automobiles in the U.S. were to be retrofit with plug-in hybrid technology. As Vandal suggested, the additional revenues would not have to be invested in new plants or transmission lines because the growth in demand would be during off-peak hours. "Try to think of any other thing that an electric utility could do to increase its capacity factor by one-third," Crane asked. He then reminded the audience that it took eight years from Alan Shepard's first orbital flight until Neil Armstrong walked on the moon. "CO2 reduction? We can do this!"

The best of the rest

Among the other highlights of Power Day was the keynote address by John Rice, vice-chairman of General Electric Co. and president and CEO of GE Infrastructure. Rice described GE's commitment to develop and manufacture products that have less adverse impact on the environment—part of its Ecomagination initiative.

Going green can simultaneously be a socially responsible effort and a source of revenue growth for a $20 billion/year business, Rice said. The private sector needs to become involved in greenhouse gas reduction, he explained, and the only way to do that is for governments to reward successful risk takers with profits. "The reduction of CO2 should have a value," said Rice.

GE went on record supporting a properly structured cap-and-trade system for carbon two days before President Bush's 2007 State of the Union address—an address suggesting a willingness to participate in an action plan to reduce global warming. Rice noted that solar energy is today where wind power was 10 years ago, ready to begin rapid growth and adoption. GE also supports federal subsidies for renewable energy such as the Production Tax Credit for wind, as well as the new incentives for nuclear power plant construction contained in the 2005 Energy Policy Act. Referring to CO2 reduction, Rice said, "The United States must lead; India and China will follow us."

Rice wasn't the only top executive of a major power generation equipment vendor to attend CERA Week. See the box for highlights of a wide-ranging interview with Philippe Joubert, president of Alstom Power Systems. Among the topics discussed were Alstom's steam and gas turbine businesses, carbon capture and sequestration in general, and, in particular, whether integrated gasification combined-cycle (IGCC) plants will ever completely replace pulverized coal plants for baseload service.

Finally, engineering/procurement/construction (EPC) contractors also had their say on Power Day. An afternoon panel session focused on the cost of fossil-fueled plant construction. Steve Edwards, an executive VP of Black & Veatch, minced no words when he said, "The capital cost of a coal plant in the U.S. has gone up 25 to 35% over the last year, and it's still rising. . . . Why? We've all heard about the rising prices of steel, copper, and other raw materials." Edwards cited three other causes:

  • Machinery supplier shops are now loaded, causing price pressure on steam turbines, cooling towers, fans, motors, and switchgear.
  • There's a shortage of EPC talent with experience on large coal projects.
  • Craft labor is not available to support the expected wave of construction that will peak in 2009-2012.

Edwards' advice: Either get your project construction contract in place now, or devise a strategy to delay construction until after 2012.
