LS Power LLC CEO Paul Siegel said on Friday the U.S. power market is largely
insulated from oil-price spikes tied to a war with Iran because oil is no longer
a primary fuel for power generation and the system now relies mainly on natural
gas. Ample U.S. shale output has kept gas prices relatively stable year-to-date.
"The grid needs a mix of generation technologies," Siegel said; LS Power is
developing solar, battery storage and new gas-fired plants.
