LCG, September 12, 2025--Entergy announced yesterday that the Public Utility Commission of Texas (PUCT) approved Entergy Texas’ proposal to build two efficient natural gas-fired power plants to support the region’s rapid growth. The combined electric generating capacity of the two facilities, the Legend Power Station and the Lone Star Power Station, will add over 1,200 MW to the Southeast Texas power grid to support new customer demand, increase reliability and lower costs for all customers. Both facilities are scheduled to commence operations by mid-2028.

Bush Admin to Release Pollution Rules Regarding Old. Plants
LCG, August 22, 2003The U.S. EnvironmentalProtection Agency is poised to release rules onpollution that will make it easier for older plants tobe renovated without pollution controlmechanisms having to be constructed.According to the New York Times and the NaturalResources Defense Council, the Bush Administrationwill release a rule some time next week allowing olderpower plants and oil refineries to upgrade facilitieswithout installing equipment that would decreasepollution .In 1977, according to the Clean Air Act, Congressmade provisions for aging power plants to avoid newerpollution laws unless new construction or renovationwas undertaken. The allowance was made in order that alarge number of coal plants would not have to be shutdown immediately after tighter pollution laws wereinstated. Since that time owners of older, "dirtier"industrial plants have walked a fine line betweenroutine maintenance and renovation.While the acting head of the EPA might validatethe law as early as next week, White Housespokesperson Scott McClellan would not verify anyaction on the new rule.Those opposed to the rule are upset that theAdministration is acting while Congress is in recessand before the EPAs likely new head, Utah Governor MichaelLeavitt, has been confirmed. Utahs director of airquality under Leavitt is strongly against the morelenient rule.Senators John Kerry and James Jeffords havealready taken advantage of the possible rule in orderto denounce the Administrations actions asenvironmentally harmful and tailored to specialinterest groups. Environmentalists have noted statistics onpremature death and asthma rates related to contaminants andparticulates in the air from plants, alleging thousandswill die earlier than expected and tens of thousandswill suffer lung troubles if the rule is instated.Owners of older plants support the rule and saythat the current laws prevent their plants frombecoming more efficient and reliable. Some insist thecost of bringing plants to current pollution limits istoo high on top of renovation costs, causing plantowners to leave older plants in their current,dilapidated state far too long.According to some sources, the new rule would allow plant owners to replaceor upgrade equipment without complying with pollutionrules if the cost of the upgrade is 20 percent or less of an amount the EPA dubs a "process unit," which refers to the key plant components already in place.While most new installations are fueled by natural gas, and are cleaner and moreefficient than older units, about half of allelectricity in the United States is still generated bycoal-fired plants.
