Plant Design

When owners of the Big Stone Plant researched air quality control system technology, they considered all available options and eventually settled on a design that was not in widespread use. Now that the

Is waste-to-energy the best greenhouse gas fighter among electric generating technologies? Or do trash burners spew dangerous air emissions? The answer may be a surprise. What electricity-generating technology results in net greenhouse gas (GHG) reductions, not just zero new emissions? According to the U.S. Environmental Protection Agency (EPA), it’s not nuclear, not wind, not solar. […]

Plant wastewater treatment is not what it once was, and changes in the Environmental Protection Agency’s effluent limitations guidelines (ELG) have added a host of new wrinkles. A panel of power plant experts discussed what plant managers are planning and doing to keep things running smoothly within the new rules. For more than three decades, […]

Fortum Värme, a company jointly owned by Finnish energy firm Fortum and the city of Stockholm on May 9 inaugurated a new biomass-fired combined heat and power (CHP) plant on the shores of Värtan, a strait in Sweden’s capital city. The Värtan CHP8 (130 MWe, 280 MWth), which began construction in 2013, will begin commercial […]

Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

Power generators have always had to make afetyome changes as each new generation enters the sector, but today’s new workers are bringing with them attitudes and skills that challenge traditional plant management, for good and ill. Here’s what some companies and plants are doing to make the best use of younger workers while getting them […]

An industry rooted in tradition is facing unprecedented changes and challenges, and meeting them requires “thinking big” and embracing disruptive technologies that will change how we think about electricity generation and delivery. That was the message from the keynote session at ELECTRIC POWER 2016.  Two senior power sector executives opened the 2016 ELECTRIC POWER Conference […]

The nuclear industry has been expecting big things from small modular reactors (SMRs) for a long time, but to date, no SMRs have reached commercial construction phase. That may change soon. Utah Associated Municipal Power Systems has a plan to deploy NuScale Power’s Integral Pressurized Water Reactor at a site in Idaho. Will others follow […]

The Department of Energy (DOE) is ready to end its involvement with the Texas Clean Energy Project (TCEP), a carbon capture, utilization, and storage (CCUS) facility under development in west Texas, a move that would effectively shut the project down, according to its backers. Along with FutureGen, Hydrogen Energy California (HECA), and NRG’s Petra Nova […]

Fuel cells powered by natural gas, biogas, and hydrogen are a rapidly expanding option for distributed generation, with fuel cell­­–based power plants being deployed in capacities into tens of megawatts. But as the technology improves and costs begin to scale, opportunities for other applications are being explored. One such application may even go beyond power […]
