Panelists debating the pros and cons of a regionalized western power grid seemed to agree that the development of such a system is inevitable, but they disagreed on how fast the evolution should occur. The panel discussion took place during the California Independent System Operator (ISO) Stakeholder Symposium held on September 7 in Sacramento. At […]

The Pilgrim Nuclear Power Plant in Massachusetts, limping toward retirement in 2019, suffered yet another unplanned shutdown on September 6 after operators were forced to power down the reactor because of high water levels in the core. According to the Nuclear Regulatory Commission (NRC) event report, “operators initiated a manual reactor scram due to high […]

Updates finalized by the Environmental Protection Agency (EPA) to its Cross-State Air Pollution Rule (CSAPR) identify nitrogen oxide emission (NOx) reductions from power plants in 22 states to help states address transported pollution under the agency’s more stringent 2008 ozone air quality standards. It marks the first time the EPA has updated an existing program […]

If wind and solar photovoltaic (PV) penetrations in the Eastern Interconnection were amped up to 30%, they would decrease coal, combined cycle, and combustion turbine capacity factors by 30% to 50%, a new study from the National Renewable Energy Laboratory (NREL) suggests. The study, NREL’s Eastern Renewable Generation Integration Study (ERGIS), was released on August […]

Owner/operator: PSEG New Jersey’s second-largest power plant has been a leader since it opened in 2006, when it was named a POWER Top Plant for its use of reclaimed water for cooling and for fitting an advanced four-unit facility into a constrained brownfield site. Now PSEG’s Linden Generating Station becomes a two-time Top Plant winner […]

Owner/operator: We Energies Converting a boiler’s fuel source from coal to natural gas involves a lot of planning and reengineering. When the plant is the sole steam service supplier to a downtown metropolitan area, it also involves a rigid schedule. The Valley Power Plant overcame several challenges to successfully complete one such conversion. The Valley […]

As combined cycle gas turbine plants are called upon to play a larger and more flexible role in the generation mix, it’s important to schedule a comprehensive assessment of major components at key intervals to ensure reliable operation. Just like humans, power plants can benefit from regularly scheduled condition assessments, which are sometimes called “health […]

Deciding to retire a coal-fired unit is often a tough call, but even tougher decisions follow. The next steps taken by a generation owner have multiple economic, environmental, and stakeholder consequences. Since 2000, U.S. generating companies (Gencos) have announced the closure of more than 200 coal-fired power plants, totaling 102 GW of generating capacity. Closures […]

Inexpensive natural gas, increased renewable energy utilization, and ever-tightening environmental regulations have limited the use of waste feedstocks for power generation. But while often dismissed out of hand, with proper planning and understanding of the market, power producers can realize benefits from waste-to-energy projects. It was a tropically hot day at the plant, and it […]
