US Lab Combats “Duck” Curve, Touts Solar Energy Grid Integration
The notorious “duck” curve is no obstacle to solar energy grid integration, thanks to some fancy footwork by the US Department of Energy’s National Renewable Energy Laboratory.
Duck Curve
What About Florida? Energy Efficiency, Solar Energy, & Regulatory Backwardness In The Sunshine State —…
For several years now, there have been increasing complaints from utilities about the resulting load shape from owners with solar systems. This is the so called “duck curve” which has gotten a lot of attention from utility alarmists. In some sense, it has been a way of claiming that rooftop solar is a profound problem for utilities. We will show here that this problem can be (and will be) solved.
Pintail Power Combines Solar, CSP, & Conventional Generation Into One Highly Efficient System
Pintail Power offers a new technology that combines solar power, conventional steam generators, and molten salt storage to take the duck curve.
Amazon’s Mighty Wind (Cleantech Talk #38)
Episode 38 of Cleantech Talk kicks off with a discussion of how, while China may be overperforming with its solar panel buildout, those panels are underperforming due to the low air quality there. Which is a polite way of saying that coal-combustion aerosols are reducing solar panels’ electricity harvest — by up to a third! (Dark aerosols, like soot, tend to absorb light; other aerosols such as sulfates and nitrates, reflect light. In both cases, the aerosols prevent light from reaching solar panels below.)
This Is The Future Of Electricity Pricing
The rapid transformation of the electricity sector will make it necessary for utilities to adopt radically new pricing methods, writes Fereidoon Sionshansi, publisher of newsletter EEnergy Informer and editor of a new book, Innovation & Disruption at the Grid’s Edge.
New Arizona Policy Would Mandate Solar After Dark
A way to incentivize the use of clean energy like solar after dark — instead of gas peakers — to cover peak loads has been proposed in a white paper commissioned by Arizona’s Residential Utility Consumer Office

Debunking the clean energy myth that the “Duck Curve” puts a ceiling on renewable energy integration
Widespread Battery Storage Will Be Bad News For Gas And Coal Generators
Originally published on RenewEconomy. International credit rating agency Moody’s Investors Service expects battery storage to become economically viable within 3 to 5 years in the US market, and the biggest losers will be electricity generators, particularly peaking gas plants. In a detailed analysis of the US battery storage market, Moody’s says … [continued]
Eventual Trillion-Dollar Market (Not Al Gore) Spurring Energy Storage Growth
By Byron Anderson Utility-scale energy storage is often discussed like it’s the flying car of renewable energy, but unlike the flying car, there is an immediate need and an eventual trillion-dollar global market to go along with it. After speaking with EnerVault’s new CEO, Ron Mosso; Temporal Power’s President and … [continued]
