Models are evolving for utility-scale solar development.
During the next few years, the biggest growth in the solar energy market will happen in the form of utility-scale projects, mostly driven by state renewable portfolio mandates. But financing such projects has become more difficult, with a smaller pool of equity capital and an evolving set of regulatory requirements.
Utility-scale projects suffer growing pains.
Anyone who’s been watching the solar power industry for more than a few years can’t help but be impressed by the recent explosion of large-scale projects. It seems akin to the rapid scale-up of wind in the late 1990s and early 2000s—when megawatt-scale turbines became standard-issue, and the definition of a “large” wind farm changed from a capacity of 20 MW to something more like 200 MW.
Solar and wind developers learn to shift project risk to the grid.
As Google says, “the wind cries for transmission.” But the opposite is true as well: without new wind and solar energy projects, we would not need to build so many new transmission lines. Each side needs the other, yet neither dares declare too soon, and risk weakening its bargaining position. That is, until one utility in California found a way to break the impasse, with each side scratching the other’s back — thus putting to rest the age-old question, “Which came first, the . . . ?”

Combined efforts bring mutual benefit.
Regardless of what drives the action — state regulation, federal policy, economic reality — collaboration between utilities and the solar industry is now becoming prevalent. Expanding definitions of utility solar business models represent a significant potential for solar market growth, and provide paths for others to follow.
Lockheed Martin teams with Tendril; Pattern Energy 101 MW wind plant starts operating; Alstom to supply steam equipment to GWF plant; Siemens wins government efficiency contract; GE Jenbacher introduces high-efficiency gas engine; OpenADR Alliance forms; Better Place gets into San Francisco taxis; EnerNOC enters TransAmerica Pyramid; and more.
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.
