Wind Integration: Incremental Emissions from Back-Up Generation Cycling (Part IV – Further Reflections)

By Kent Hawkins -- December 16, 2009

Three previous posts have examined the emissions problem related to intermittent industrial windpower that is firmed up with fossil-fuel generation.

  1. Part I presented a framework of the necessary considerations and an interim assessment of the effects on fossil fuel consumption and CO2 emissions until sufficiently comprehensive studies can be performed in the areas indicated. This analysis shows approximately the same gas burn and an increase in related emissions, including CO2, compared to the no-wind case.
  2. Part II reviewed the simplistic, incomplete approach that is usually claimed by wind proponents and policy makers. Introducing necessary considerations shows the dramatic, negative impacts presented in Part I.
  3. Part III critically reviewed an article by Milligan et al, introduced in a post on Knowledge Problem in response to Part I. The Milligan article claims negligible reductions from the theoretical maximum and contains questionable material.

Smart Grid: Can ‘Smart Metering’ Overcome the Hassle Factor? (transaction costs matter too)

By <a class="post-author" href="/about#robertmichaels">Robert Michaels</a> -- May 29, 2009

When asked for conjectures about the Smart Grid, economists’ imaginations become almost indecently fertile. Writing in her blog, market-friendly Lynne Kiesling sees astounding dividends from real-time pricing and smart grid technology, preferably with competitive retail service.

Say, for example, you are on the train to work, and you get a SMS [ text message] notification that due to unexpected weather, there will be a higher-than-normal electricity price in the 9:00-10:00 hour. You may have already programmed your devices to respond to price signals, but what if the price is high enough that you want to change your settings? You can log in to your HAN [Home Area Network] from your mobile device, or from your computer at work, and change the device settings in the home through the web portal. … [i]f the home has e.g.
