The Progress of Power Technology
I’ve developed something of a love/hate relationship with awards. Initially, it’s exciting to spot outstanding or unusual projects for our POWER awards, but over time, any number of things can happen to those plants, making them appear less than stellar. Sometimes it’s changing policy or market conditions that make a record-setting plant completely uneconomic (see […]

More Communities Choose Their Own Energy Future
As the effects of climate change have increased and renewable energy is becoming cost-competitive with conventional forms of energy generation, more and more towns, cities, and counties are pushing their local utilities to increase the amount of renewables in their energy portfolios. While many utilities are embracing this shift to renewable energy, others are slow […]

All About Lubricant Additives
Lubricant additive technology is a complicated business because it involves several different chemistries. Often, one additive can adversely interact with another additive as they both compete for the same area on substrate surfaces. This kind of interaction can lead to the canceling of the additives’ desired properties. Conversely, the use of different additive chemistries can, […]

Time to Catch the Sea Breeze? Offshore Wind Power Development in China
After years of planning and sluggish development, 2016 may be the year that offshore wind power development takes off in China. Once it does, the market will be large. Offshore wind power has a very important role to play in easing power shortages in coastal areas of China and in responding to climate change effectively. […]

Dusseldorf’s Lausward Power Plant Fortuna Unit Wins POWER’s Highest Award
Düsseldorf’s new “Block Fortuna” at the Lausward Power Plant, owned by municipal utility Stadtwerke Düsseldorf, is setting records and giving Germany’s coal-fired power plants some much-needed competition for backing up the nation’s large percentage of variable renewable power. Germany’s Energiewende (literally, “energy turn”) functions as something of a living laboratory, where innovation equals survival, because […]

Prevent Purified Water from Putting a Damper on Your Next Commissioning
When commissioning a new power plant, requirements for purified water can be large—often more than an unfinished plant can supply. When it’s time to bring in outside help, proper planning can help avoid problems and keep budgets under control. With all the complexity inherent in the commissioning of a power plant, the last thing anyone […]

Longview Power Plant Rehabilitation Results in Most Efficient U.S. Coal Plant
We’ve all probably purchased a “lemon”—an item that didn’t work as advertised—but when that lemon is a $2.1 billion power plant, you can’t just return it. For Longview Power’s management team, taking a “belts-and-suspenders” approach to problem-solving allowed them to identify root causes, make changes, and convert their lemon into “lemonade.” Most people expect a […]
