Breckinridge County Schools � �■ s� � CMTA <br />Guaranteed Energy Savings Contract <br />Annual Reconciliation Report (2023-2024) <br />Solor <br />Solar PV arrays were installed at Hardinsburg Elementary School and Irvington Elementary School. As this <br />was the only ECM performed at these facilities, savings are not guaranteed relative to a building baseline, <br />but instead a production level of electricity is guaranteed. Solar production was guaranteed using Option <br />B: Retrofit Isolation, where the solar inverters record all electrical production from the arrays. <br />Note that the solar inverter at Irvington Elementary School failed on May 10, 2024 and was replaced under <br />warranty by CMTA at no cost to Breckinridge County Schools on July 11, 2024. As such, there was no solar <br />production at Irvington Elementary School during the 2-month period where there was no functioning <br />inverter at that site. <br />100,000 <br />80,000 <br />k 60,000 <br />W <br />h <br />40,000 <br />20,000 <br />0 <br />Solar Production Tracking <br />Hardinsburg Elementary School Irvington Elementary School <br />■Guaranteed Production ■Actual Production <br />Figure 4-5: Solar Production Tracking Year 4 <br />Figure 4-5 shows that Hardinsburg Elementary's solar array exceeded the production guarantees for Year <br />4 while Irvington Elementary had a shortfall due to two months of lost production as a result of the failed <br />solar inverter at that site. This issue has since been corrected and solar production has returned to <br />projected levels. This small shortfall in production is exceeded by the excess electrical savings at other <br />district sites (see Table 4-7). <br />Page Content is Subject to Confidentiality Restrictions <br />4-6 <br />9519 Civic Way, Suite 100 1 Prospect, KY 40059 1502.409.4062 1 cmta.com <br />Performance Contracting I M EP Engineering I Zero Energy Engineering I Technology I Commissioning <br />
