“Locational Marginal Pricing” Grad Class Now Available Online

ross baldick logoNow you can attend my “Locational Marginal Pricing” grad class online. And it’s free!

I’ve been teaching courses on locational marginal pricing for 10 years. Locational marginal pricing is now used in all US restructured markets and in New Zealand. Its key insight is to reflect into market prices the effect of limitations on electric transmission capability. The model has origins in the seminal and astounding work of Fred Schweppe and others in the 1980s and has been in place in parts of the US since around 2001.

The online version of the course (produced in cooperation with the Consortium of Universities for Sustainable Power (CUSP) at the University of Minnesota) is now available for free download from the CUSP website: http://cusp.umn.edu/emarkets.php.

Battery Swapping a Winner for Tesla’s Model S

I recently visited the Tesla store at the Domain in Austin to check out the Tesla Model S.  The compact layout of the electric drivetrain allows for a trunk at the front of the car — a “frunk”– in addition to conventional trunk space.

The Tesla Model S is a truly beautiful car, but in a previous post I voiced my concern about the effect on the electricity grid of high-power charging stations such as the Tesla Supercharger.

In this Tesla video, Tesla founder Elon Musk demonstrates battery swapping with the Tesla Model S. Despite the recent demise of Better Place (a company that was developing battery swapping technology), battery swapping lives on at Tesla. Battery swapping is a potential game changer, providing faster “charging” than filling the gas tank (the paradigm that concerns me for electric charging), while allowing the battery packs to be electrically charged more slowly. Battery swapping delivers fast “charging” without the electricity infrastructure costs of large-scale high speed electric charging. It also retains the potential positives of off-peak electrical charging, including matching of electrical charging to renewable production. Bravo to Elon Musk and Tesla!

Does Texas Have a Generation Capacity Problem?

capacity adequacy panel“Are Capacity Markets Necessary to Ensure Adequate Generating Reserves?” That was the title of the panel I moderated at the third annual Austin Electricity Conference (sponsored by The University of Texas McCombs School of Business, School of Law, and Cockrell School of Engineering on April 18 and 19.)

The conference theme — “Resource Adequacy in Competitive Electricity Markets” — is an issue of great importance here in Texas, where we have concerns about whether we will have enough generation capacity in coming summers.

Several electricity markets in the eastern United States include a “capacity market,” or central procurement of generation capacity for anticipated peak load, typically arranged three years into the future. Texas does not have a capacity market, relying instead on occasional high prices (and anticipation of high prices) in the wholesale market to encourage investment in generation.  Various tweaks have been made to this basic principle of an “energy-only” market, and a current proposal by Professor William Hogan of Harvard University  suggests a “demand curve for reserves.”

In my presentation, “Are Capacity Markets Necessary to Ensure Adequate Generating Reserves?” I lay out the fundamental issues and outline potential solutions.
