A new future for small coal-fired plants.
Small coal-fired plants are particularly vulnerable to economic and environmental pressures, putting some plant owners in what seems like a no-win position. But an emerging option—biocoal from crop wastes—might give small coal units a new lease on life.
Waste fuels struggle despite coal’s decline.
Fuel supply might be the biggest barrier to scaling-up biomass power generation, but it’s by no means the only problem. Utility projects to repower coal-fired plants face permitting challenges, ballooning technology costs and strained economics. Some owners are giving up the fight.
Smart-grid planners feel the heat.
State utility regulators begin to question the benefits of smart grid technology, and customers take to the streets in public protests and demonstrations to oppose installation of smart meters.
TransCanada floats $1.25 billion in a two-tranche bond offering; KinderMorgan sells $1 billion in notes; Xcel Energy raises its offering to $500 million; plus bond issues from Calpine, SDG&E, FPL, PSE&G and Entergy, totaling more than $4 billion in May 2010.
Synchronizing networks to bring green power to market.
In order to fully integrate wind and other dispersed sources of energy into the system, America’s patchwork transmission networks need to be more closely interconnected and synchronized. An advocate for the Tres Amigas merchant transmission project explains how the proposed facility will integrate the grid.
Automation technologies promise a reliability revolution.
Utilities are using automation and back-office systems to improve their performance on outage management and service restoration. The next generation of smart-grid technologies promises a revolution in self-healing systems. But first the industry must gain confidence in the technology—and the business case for investment.
