Energy companies made announcements big-dollar deals this week to expand liquefied natural gas facilities, but down price could have an impact on a broad range of construction projects.

Topping the list is the massive Sabine Pass LNG project in Cameron Parish, La. Cheniere Energy Partners announced that it had entered a $2-billion equity investment agreement with Blackstone on Monday.

Cheniere has multiple long-term sales and purchase agreements in place for LNG produced at Sabine Pass, including GAIL, Ltd., Gas Natural Fenosa and BG Group.

On Tuesday, Lone Star NGL, which is joint venture of Energy Transfer Partners and Regency Energy Partners announced that it will construct a second 100,000-barrel-per-day natural gas liquids fractionation facility at Mont Belvieu, Texas. Cost is estimated at $350 million.

However, sagging natural gas prices could have a near-term effect on a broad range of public work. Natural gas prices are currently at the lowest levels in a decade. The Fort Worth Star-Telgram reported Wednesday that local governments, bolstered by more than $1 billion from the Barnett Shale over the past four years, are adjusting to diminished windfalls as the lowest natural gas prices in a decade have slowed drilling and reduced royalties.” Fort Worth lowered projected gas-related revenues by 32%--from $1 billion to $697 million.
