The Grid Needs a Symphony, Not a Shouting Match

Our blog post this week was authored by our friends and fellow Coloradans at the Rocky Mountain Institute (RMI). We think it's one of the best posts we've read in a while, and RMI kindly gave us permission to share it. 

In April, U.S. Secretary of Energy Rick Perry announced a 60-day study on electricity market design and grid reliability, meant to assess to what extent current market designs fail to adequately compensate “baseload” (i.e., coal- and nuclear-fired) power plants.

The memo commissioning the study presents as “fact” a curious claim: “baseload power is necessary to a well-functioning electric grid.” This notion has been thoroughly disproven by a diverse community of utilities, system operators, economists, and other experts that moved on from this topic years ago. To these practitioners, this premise seems as backward as if President Eisenhower, instead of launching the interstate highway system, had called for restudy of the virtues of horse-drawn carriages.

Today, the grid needs flexibility from diverse resources, not baseload power plants. Leveraging market forces to help us decide between options offers the best chance of avoiding the multitrillion-dollar mistake—and gigatons of carbon emissions—of blindly reinvesting in the past century’s technologies.

Capturing the Full Benefits of Demand Flexibility

By Ginger Juhl on Aug 11, 2016 9:00:00 AM

This blog was co-authored by Enbala and the Rocky Mountain Institute (RMI). Enbala extends its heartfelt thanks to the Institute for the insights and effort that went into creating this piece. 

INTRODUCTION:

Demand flexibility - allowing household devices like HVAC systems and smart appliances to interact with the electric grid in response to real-time price changes - can save customers money and lower the overall cost of electricity. The Rocky Mountain Institute's recent paper, The Economics of Demand Flexibility, analyzed the economics of making common household loads controllable and responsive to electricity price signals. The Institute found that just making two devices flexible, i.e., smart thermostats that could flex an HVAC system’s output up or down by 2 degrees and smart water heaters that could change the timing of water heating, could lower system-wide peak demand by eight percent and save $10–15 billion in costs to the grid annually.
