Council tables decision on GRDA power purchase extension after lengthy utilities briefing
Summary
The council tabled action on a proposed extension to the GRDA power purchase agreement — options discussed included 4.5 MW and 9 MW capacity levels; the Utilities Advisory Commission and the City’s wholesale supplier KMEA recommended the 9 MW option, and council asked staff for more time and the presentation to be emailed to members.
The Gardner City Council on Feb. 1 voted to table consideration of an extension to the city's power purchase agreement (PPA) with Grand River Dam Authority (GRDA) after a detailed presentation by utilities staff and questions from council.
Utilities staff presented historical contract terms and comparative scenarios. Staff noted the city’s existing GRDA PPA (originating in 2005) provides seasonal accredited capacity (about 9 megawatts June–September; about 6.75 megawatts October–May under current terms) and described line items including capacity charges (cited as 10.45 kilowatt-month, approximately $945,000 annually), energy costs (about $2.6 million annually including PCA) and a KMEA fee of about $11,000 per month. Staff summarized analyses that compared GRDA PPA costs with purchasing in the SPP day-ahead and real-time markets and presented three options, including retaining or adjusting accredited capacity at 4.5 MW or 9 MW.
Why it matters: The PPA decision affects the city utility’s future capacity availability and long-term energy costs. Staff noted trade-offs: higher contracted capacity (e.g., 9 MW) raises guaranteed capacity and reduces near-term capacity risk but increases contracted costs; lower contracted capacity can rely more on day-ahead or real-time market purchases but carries volatility risk, as seen in winter 2021’s polar vortex.
Council discussion and outcome: The Utilities Advisory Commission and KMEA had recommended the 9 MW option. Multiple councilmembers asked for more time to review the spreadsheet of comparative costs and to receive the staff presentation by email. The council moved to table new business item number 3 and asked staff to circulate the materials; the motion to table carried.
Next steps: Staff agreed to email the presentation and supporting spreadsheets and to return the item to council before the March 31 deadline for notifying KMEA of the city’s decision.
