Feb. 29, 6 pm: Utility Scale Battery Storage – Especially the Flow Battery

Utility Scale Battery Storage:
Especially the Flow Battery

Professor Michael Marshak, Ph.D.
Assistant Professor of Chemistry
University of Colorado Boulder

6:00 pm Event Begins
5:30 pm Light Refreshments
Boulder Main Public Library
Boulder Creek Room – Main Floor

Michael Marshak, Ph.D., is an assistant professor of chemistry at
CU-Boulder. His research program spans the fields of organic and inorganic chemistry to make new chemicals and materials. Specifically, he plans to investigate organic reactions featuring new transition metal catalysts, nanoparticle and thin-film materials, and chemical transformations related to biomass and carbon dioxide.

Michael has helped to pioneer the use of organic materials called quinones for flow batteries, a promising new technology that can store massive quantities of energy on the electric grid. Flow batteries can enable greater use of renewable energy resources such as wind and solar by providing power when the sun isn’t shining and the wind isn’t blowing. His interest in batteries is now focused on the design of new chemistries that could enable solar-powered homes and businesses to go off-grid.

Power Plants and the “War on Coal”
Special CU Guest Lecture: Richard Revesz

Wolf Law Building, Room 207
University of Colorado School of Law


Struggling for Air: Power Plants and the “War on Coal” chronicles Richard Reveszthe fateful decision by Congress to grandfather existing coal power plants from the permitting requirements to install modern pollution control technologies and the health, legal and political reverberations of this crucial decision including the long struggle of Republican and Democratic administrations alike to reclaim public health safeguards in light of the heavy multipollutant burden from existing power plants and the perverse and potent incentives grandfathering created for prolonging the utilization of aging, inefficient and high emitting existing plants.

Tell the PUC to Uphold Boulder’s Right to Municipalize

Act Now: Tell the PUC to Uphold Boulder’s Right to Municipalize

On November 4, 2015 the Colorado PUC is scheduled to hear Xcel’s Motion to Dismiss Boulder’s application for separation from the Xcel system. We hope you will express your support for the City of Boulder with a short message to the PUC and if you can, by attending the actual proceedings (business attire is best.)

Boulder has a clear Constitutional right to form a municipal utility, but of course Xcel would like to stifle that right in its effort to maintain its monopoly status and to continue to provide electricity that is dominated by coal and natural gas.

If you believe Boulder’s Constitutional right to municipalize should be respected (and/or think we can do better than 30% renewable energy!), then please send a quick note to the Colorado PUC.

Defend Freedom to Access Local Clean Energy

The Honorable Kimberly D. Bose, Secretary
Federal Energy Regulatory Commission
888 First Street, NE
Washington, DC 20426

Dear Ms. Bose,

We, the undersigned, urge the Commission to find that Tri-State’s proposed lost revenue penalty proposal contained in Tri-State’s revised Board Policy 101 is inconsistent with the Public Utilities Regulatory Policies Act of 1978 (“PURPA”) and the Commission’s implementing regulations.

Rate penalties placed on purchases of power from local qualifying facilities appear to run counter to the spirit and the letter of PURPA. PURPA Section 210 states an intention to “encourage cogeneration and small power production” through rate setting that is “just and reasonable to the electric consumers of the electric utility and in the public interest.”

As we consider the public interest in mitigating climate change and in promoting local economic development, we ask that the Commission deny approval of Tri-State's lost revenue penalty. Tri-State's proposal penalizes utilities like Delta-Montrose for buying local renewable energy that the Commission has said Delta Montrose is obligated to purchase. Approving the rate penalty would essentially undo the Commission's previous decision and hinder, rather than promote, local renewable energy development.

For these reasons, we urge you to reject Tri-State's proposed lost revenue penalty.

How much renewable energy could we use and keep costs competitive in Colorado?

October 19th: Renewable Energy By the Numbers
5:30 pm Light Refreshments
6:00 pm Event Begins
Boulder Main Public Library
Boulder Creek Room – Main Floor

Join Clean Energy Action, Empower Our Future, and others to find out how much renewable energy we could use and keep costs competitive in Colorado. Tom Asprey, from the Empower Our Future citizen group, has built a detailed spreadsheet model to ask and answer that question over a very broad range of assumptions. Come hear what he learned and get answers to your questions about what our energy future could look like.

The result of Tom’s model are very encouraging and support your intuition that if we invest in clean energy now we can save significant amounts of money going forward–and greatly reduce our greenhouse gas emissions and start to live within our “fair share” carbon budget at the same time.

A op-ed describing the model results can be found here.

The goal of the meeting is to give an initial introduction to the model and preliminary conclusions found using it.  The public will receive an initial understanding of how the model is structured, how it works and what it shows.  They will be invited to collaborate, to ask questions, to provide feedback and to make suggestions on improving the model in ways that address their concerns.  This is intended as a first session.  Future public sessions will follow and requests for individual sessions can be made by appointment on the EmpowerOurFuture website.

Tom Asprey – Retired Electrical Engineer (BSEE) is a member of IEEE, AAAS and ACS.  Worked on modeling and design of computer chips and systems at HP and Intel for 27 years before retiring.  Tom served on various City working groups that supported and evaluated the municipal electric utility proposal.  This is Tom’s fourth model of a proposed Boulder municipal electric utility.
