California Will Soon Be Home To The Country’s Largest Floating Solar Array

Submitted by aburr on Tue, 2015-03-17 13:22

Sonoma Clean Power will build the largest floating solar array in the U.S., a project that’s scheduled to be completed in 2016 and will create enough energy to power 3,000 houses. The array will span six wastewater ponds filled with treated sewage. Floating solar, which typically involves installing solar panels on pontoons that rest on the surface of a body of water and is also called “floatovoltaics”, has been installed in California before.

McConnell Maligns Clean Power Plan

Submitted by meacott on Wed, 2015-03-11 17:47
Senate Majority Leader Mitch McConnell, R-KY, is now asking the states to disregard the EPA’s Clean Power Plan, saying it is economically disadvantageous. His calculus, however, fails to consider the financial gains from investments in modern technologies.

Those of us following the politics of coal country and throughout the Appalachia region understand the popular political sentiment there – that coal is the lifeblood of the area and that President Obama is poisoning the well. So it’s no surprise that Senate Majority Leader Mitch McConnell, R-KY is now urging not only his state but others to buck the Clean Power Plan, proposed last June by the U.S. Environmental Protection Agency (EPA) and backed by the White House.

Splitting the Difference on Coal Ash

Industry wins exemption for ‘beneficial use’ but faces tighter rules on impoundments and landfills.

The EPA only has limited authority to implement and enforce a Subtitle D nonhazardous waste rule, like the coal combustion residuals rule. As a result, EPA had to promulgate the standards as “minimum federal criteria” that states are encouraged to adopt as part of their Subtitle D programs (but EPA cannot actually require states to adopt or implement these requirements.) Nonetheless, the new minimum criteria do indeed serve as legal standards that an owner or operator of a coal combustion residuals disposal unit must meet.

Reaching for the Cloud

Utilities house pools of data in the Internet ecosystem, striving for efficiencies.

Business decisions may be easier to come by at utilities now that new technologies are capturing their data from a multitude of sources and storing it in the “cloud” where it can be accessed by analysts and authorized personnel.

Electric Vehicle Charging: Tariffs and Tradeoffs

We examine various types of charging strategies and infrastructure available today and report on the experience gained from rate structures for electric vehicle charging now being offered at four different utilities. These findings lead us to provide recommendations to achieve more productive use of the electric grid.

Energy Storage: The Utility's Best Friend

Perhaps the best way to think of energy storage is as an injection of much-needed intelligence for the grid. Energy storage will fine-tune the relationship between a bewilderingly complex asset base and a sprawling, diverse and demanding spectrum of customers in real time. Energy storage systems will act like energy grid computers and control systems, not just bulk repositories for electrons.

Rethinking Regulation

Not so Fast: Why the Electric Industry May be Heading in the Wrong Direction

Utility regulation will often display the power of special interests, which may only appeal to a narrow set of interests. Public officials need to step and serve the broader public.
