Kansas City Power & Light said in an updated integrated resource plan (IRP) filed June 20 at the Missouri Public Service Commission that the preferred option would see the retirement of the 170-MW, coal-fired Montrose Unit 1 in 2016.
That probable retirement is being driven by various pending or imposed pollution rules, like the Mercury and Air Toxics Standards (MATS). If MATS is killed through pending federal court appeals of that U.S. Environmental Protection Agency program, then the Montrose 1 retirement could be delayed, but probably only until 2019, when costly new NOx controls would be needed for other reasons, the IRP noted.
Montrose Units 2 and 3 (340 MW total) are currently scheduled for retirements in 2021, mostly due to an assumption that new coal combustion residuals (CCRs) rules contemplated by EPA would take effect in 2021. Those rules would likely require an expensive wet-to-dry conversion of the plant’s CCR disposal operations. If EPA doesn’t issue the CCR rule, at least in the form that KCP&L fears, then the retirement of these coal units could be delayed, though in this case likely only to about 2023, when expected National Ambient Air Quality Standards (NAAQS) would likely force SO2 scrubber, baghouse and selective catalytic reduction (SCR) installations at these units.
On the plus side of the ledger in terms of capacity, KCP&L currently plans in the 2013-2033 IRP period to add:
- 17 MW of new solar (11 MW in 2018 and 6 MW in 2021);
- 400 MW of wind (50 MW in 2016, 150 MW in 2020 and 200 MW in 2024); and
- 386 MW of gas-fired combustion turbines (193 MW in 2026 and 193 MW in 2031).
