KCP&L Greater Missouri Operations Co. (GMO) filed on April 1 at the Missouri Public Service Commission an integrated resource plan that relies on part on new solar additions and also the ongoing emissions retrofits of existing coal-fired generation.
Based in part upon current Missouri Renewable Portfolio Standard (RPS) requirements, the Preferred Plan includes 10 MW of solar additions and 310 MW of wind additions over the 20-year planning period. The solar resource addition in 2016 is expected to consist of ownership in 2 MW of Commercial and Industrial rooftop installations and 3 MW of a central station solar facility.
A 260-MW wind addition in expected to be in service in 2017. A 50-MW wind addition in 2019 represents the balance of the Gray County wind facility at which GMO currently holds a 60-MW share.
The Preferred Plan reflects Sibley Units 1 and 2 ceasing to burn coal in 2019 and the 96-MW Lake Road 4/6 converting from coal to natural gas in 2016 and then retiring in 2020. The environmental drivers that contributed to discontinuing coal use, and the Lake Road 4/6 retirement, include the EPA’s Mercury and Air Toxics Standards, Ozone National Ambient Air Quality Standards (NAAQS), PM NAAQS, Clean Water Act Section 316(a) and (b), Effluent Guidelines, Coal Combustion Residuals Rule, and the CO-2-reducing Clean Power Plan. These rules will be monitored by GMO to determine if the decision to cease burning coal and to retire Lake Road 4/6 in the projected retirement year of 2020 continues to be prudent.
The Preferred Plan was not the lowest cost plan from a Net Present Value of Revenue Requirement (NPVRR) perspective. The Alternative Resource Plan GBBBA had the lowest expected NPVRR of all modeled plans which also retired Lake Road 4/6 in 2020 and incorporated a Realistic Achievable Potential [Demand Side Management] level. The Preferred Plan has a slower implementation of DSM, but results in a lower 20-year levelized rate impact and lower NPVRR impact for much of the 20- year period.
Based on the 2015 Preferred Plan for GMO, retrofits are currently being undertaken at the coal-fired Sibley Station and Lake Road 4/6. While the Preferred Plan calls for Sibley 1 and 2 to cease burning coal by 2020 and Lake Road 4/6 to be retired, minor retrofits are needed by 2016 for MATS compliance at Sibley Station and Lake Road 4/6 is installing fuel oil backup.
GMO is an integrated, mid-sized electric utility serving portions of Northwest Missouri including St. Joseph and several counties south and east of the Kansas City, Missouri metropolitan area. GMO also provides regulated steam service to certain customers in the St. Joseph, Missouri area.
