South Dakota Public Utility Commission (SDPUC). The supplemental filing updates OTP&#8217;s original 2022 Integrated Resource Plan (2022 IRP), which was filed on September 1, 2021. In the supplemental filing, OTP outlined its updated plan for meeting customers&#8217; anticipated capacity and energy needs while maintaining system reliability and low electric service rates, in light of several changes that have occurred since the original filing, including significant winter and spring reserve planning margins adopted by the Midcontinent Independent Service Operator (MISO), tax credits made available for renewable energy projects under the Inflation Reduction Act, the enactment of the Clean Energy Bill in Minnesota, and recent volatility in energy and capacity markets. </span></div><div style="margin-bottom:3pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The major requests in OTP's supplemental filing include:</span></div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">&#8211;</span><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.52pt">the addition of on-site liquified natural gas fuel storage at our Astoria Station natural gas plant in 2026;</span></div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">&#8211;</span><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.52pt">the addition of approximately 200 megawatts of solar generation in 2027-2028; </span></div><div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">&#8211;</span><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.52pt">undertaking the initial steps necessary to add approximately 200 megawatts of wind generation in 2029; and</span></div><div style="margin-bottom:6pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">&#8211;</span><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.52pt">a withdrawal from our 35 percent ownership interest in Coyote Station, a jointly-owned coal-fired generation plant, in the event we are required to make a major, non-routine capital investment in the plant.</span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">We are also planning to repower four of our existing wind facilities in 2024-2025. </span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Consistent with the original 2022 IRP, the supplemental filing proposes to, subject to regulatory approval, create a regulatory asset to recover costs related to any future withdrawal from Coyote Station, should such a withdrawal occur, including the net book value of the plant on the withdrawal date, anticipated decommissioning costs, and any costs incurred if a termination of the existing lignite sales agreement under which Coyote Station acquires all of its lignite coal fuel from a nearby mine is necessary. As part of its economic analysis, OTP developed an estimate of the reasonably foreseeable costs of withdrawing from Coyote Station, which was determined to be $68.5 million, assuming a withdrawal at the end of 2028. These costs may differ from actual results due to the uncertainty and timing of future events which could result in a withdrawal from Coyote Station.</span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Compared to the preferred plan outlined in our original 2022 IRP filing, our supplemental filing adds more renewable generation resources to our portfolio, and in light of new seasonal reserve margin requirements, updates the circumstances for the potential withdrawal from our ownership interest in Coyote Station.</span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:700;line-height:120%">Forward-looking Statements</span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Calibri',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Except for historical information contained here, the statements in this Current Report on Form 8-K are forward-looking and made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
