After nearly a year, the EIRP is entering its final phase, with a fourth public meeting scheduled for Tuesday, Sept. 29, from 6-8 p.m. at the Leon Young Service Center at 1521 South Hancock Expressway.Here a few more shots from a recent CAG (Customer Advisory Group) meeting with CSU officials:
Staff and the Customer Advisory Group (CAG) have used scoring to narrow the final selection of portfolios and will recommend one portfolio, with possible amendments, to the Utilities Board at its Oct. 21 meeting.
The nine portfolios that were scored reflect rigorous technical, risk, and financial analysis, with additional consideration given to dispatchabililty, portfolio diversity, public input, societal benefits, customer resource preference, development risk, and transmission reliance. Overlaying the process is the final determination on Aug. 3, on the federal Clean Power Plan to reduce carbon dioxide from power plants in the U.S. by 32 percent below 2005 levels, by 2030.
While the focus at the public meeting will be the final three portfolios that scored the highest and had CAG review and support, information on all ten will be available.
The three top portfolios that came out of the CAG discussion were D, F, and H. Portfolio E was largely dropped due to the high cost of DSM in later years, and although some preferred Portfolio I, the group was able to support D if additional options are presented for Drake 5. Those additional options include decommissioning the unit permanently and "mothballing" which would preserve the facility without using it - leaving the possibility that it could be restarted sometime in the future.
"The group felt portfolio D was balanced, supported the community's desire for more renewable energy and DSM while controlling costs, minimized risk, and is cost-competitive with and without the Clean Power Plan," said Project Manager Katie Hardman. "It can also transition easily to Portfolio H which has a phased decommissioning of the Drake Power Plant by 2029."
Participants at the Sept. 29 meeting will be able to view the breakdown of each of the final three portfolios by topic area: emissions, energy resources, and by cost. Everyone will have an opportunity to add their respective pros and cons to the final portfolios.
The presentation to the Utilities Board is scheduled for Oct. 21, with a final decision potentially at its Nov. 18 meeting.
The flow of decisions
The nearly year-long EIRP process has humble beginnings. It began with a review of previous assumptions and new inputs, including the latest in technical advancements, customer survey trends, and forecasts. From there, staff worked the Customer Advisory Group and obtained public input on the types of energy futures they should plan and model.
That began a series of 85 "what if" scenarios, eventually leading to 10 potential portfolios, from which staff and the CAG used metrics and scoring to determine the highest-scoring portfolios that were then scrubbed by the CAG for feasibility.
