Other Contract Terms
• Maintenance and Operations (Bi-Annual)
o Mechanical, Electrical, Rack System, Vegetation, Monitoringo $7,800.00/per year + 2% annually
o Module Cleaningo $6,137.00/per year + 2% annually
• Output Guarantee Agreement
o 25-year guarantee providing the District with 99% solar production
• True-Up Payment Analysis
o Conducted every 3-years
o 2018 true-up $47,314.02 (paid Spring 2019)
True-Up Payment Overview• 2018 True-Up Payment Analysis
o Visalia: Output/generation has met or exceeded cost savings guarantee per contracto $22,890.28
o Tulare: Output/generation has been lower than expectedo $(70,204.30)
o Total True-Up Paymento $47,314.02
• Corrective Actiono Borrego recommended an adjustment for the Tulare system equipment to be stowed at a 45-degree tilt
overnight versus the horizontal tilt the system has been utilizing since startupo Borrego believes the change in tilt will reduce soiling losses when the panels have dirt build up
• Next True-Up Payment Analysiso November 2021

Sustainability Plans & Ideas • Current & Past Practice
o Continue to upgrade HVAC, lighting systems when doing district-wide remodelso Capital construction, implement California sustainability goals in the planning/design of the
Educational Support Services Building
• Energy Conservation & Energy Efficiency Services RFQo Compass Energy Solutionso Energy Audit started in September 2020o Firm to identify energy efficiency projects to maximize and assist with compliance with the California
Community College Sustainability Policy
• Future Plans & Ideaso Compliance with California Community College Sustainability Policyo Maximize district one-time funding and/or potential future bond funding to implement energy savings
projects resulting in general fund savingso Target Locations: Visalia and Hanford Campuses
• PPE distributiono Masks, gloves, sanitizer spray/microfiber cloths, disinfecting wipes, hand sanitizer
dispensers
• Awareness/wayfinding signage
• Disinfecting (using GenEon fogger)o Classrooms immediately following each session (orange/blue signage)
o Offices and public areas nightly and upon request
• Exposure mitigationo Building/area vacated for 2 days, 24-hour ‘flush’ of 100% outside air, disinfecting (fog) by
custodial staff 2x daily
GenEon Disinfectant
• What is hypochlorous acid?o Nature’s oldest disinfectant.
o Ingredient that gives bleach its microbial power.
o Same substance your white blood cells produce to fight off infections.
o Eliminates all bacteria, mycrobacteria, spores, fungi and viruses within seconds (COVID-19 within 3 minutes).
o 80-200x more effective than bleach and is 100% safe.
o “Rain” in the produce section at your local grocery store.
Indoor Air Quality
• Filtrationo Ultraviolet (UV) lighting installed in all air handlers
tied to chiller systems.
