RFQ Response for Guaranteed Energy Savings Contract South Bend Central Fire Station & MILK Dream Center Solar PV City of South Bend, Indiana 9. Financial Guarantees a. Describe your approach to creating and delivering on the savings guarantee. Include: i. Methodology to calculate savings guarantee. CMTA • *• As mentioned in Section 8, CMTA would utilize the IPMVP Option B as our method of guaranteeing project energy savings without adjusting the baseline in any way. We believe that the energy savings guarantee should be based on what is actually recorded at the meter -level and not based solely on normalized simulation results. In the case of wholistic building projects, we believe Option C best captures the true performance of a building. For stand-alone solar projects, Option B is the most accurate representation of a project's performance. Whole -building metering could skew the measurement of solar production based on occupancy levels or other factors where as Option B directly measures the array performance at the inverters where the electrical production is transmitted to the building. As shown in the following sample energy conservation measures (ECM) table, it is CMTA's preference to include as much savings as possible by utilizing the Whole Building, Option C way to verify performance, but Solar PV is the perfect use -case for an Option B guarantee.

The savings are calculated according to actual utility costs, and it is not our practice to apply weather -adjustments or other transformations to the raw production data. In layman's terms, we directly measure the electricity produced by the solar PV array and compare that to the annual production guarantee. Thus, our measurement and verification method is very straightforward: Energy Produced = Energy Saved ii. Position on stipulated savings. CMTA is the only ESCO to consistently provide guarantees exclusively using true -meter data such as IPMVP's Option e & C as the method of guaranteeing project savings. On each of our projects, we stake our reputation on the real -life performance of our guarantee, not our ability to generate compelling computer models. CMTA does not guarantee savings based on the stipulated option D, which uses computer -generated simulation models, unless specifically requested by the City of South Bend. Simulation models are used only to help develop savings calculations and project future energy consumption. We believe that the energy savings guarantee should be based on what is actually recorded by the meters and not based on stipulated projections. iii. Any non -utility cost savings that will be calculated or estimated (e.g., staff time, materials, deferred maintenance). For this project, there are no additional non -utility cost savings projected although CMTA will perform a utility rate analysis on each building to ensure financial savings are optimized. iv. Explain how these savings are calculated. As stated in section 9.i above, CMTA would utilize IPMVP Option B, Fully Metered ECM Isolation, to calculate savings. Simple arithmetic is used to compare post -project electrical production to the annual guaranteed value.
