1. Next Phase Solar Project Update
Dan Howell, C.P.M.
November 2, 2016

2. Background 5.5 MW’s Currently Installed Anticipated Production
12.4 million Kwh’s per year
Renewable Capacity > 50% at Installed Facilities
Nearly 20% of total Electrical Needs

3. Next Phase Solar Opportunities
Feasibility Assessment:
TerraVerde Renewable Partners
Approved by Board on August 17, 2016
30-Week Project Assessment

4. Project Schedule Project Phase Time Frame
Phase 1 – Due Diligence Data Gathering
9 Weeks
Phase 2 – Feasibility Analysis
7 Weeks
Phase 3 – Financial Viability
5 Weeks
Phase 4 – Develop Report and Review
Phase 5 – Implementation Plan
4 Weeks

5. Scope of Work
RES – BCT (Renewable Energy Self-Generation Bill Credit Tariff Program)
Up-to 5 MW’s per Installation
Transfer $ Credit to “Benefitting Accounts”
Limited to Local Government Entities
NEM (Net Energy Metering ) 2.0 Program
Removes MW Size Limit
Provides $ Benefit Covering both Generation and Transportation

6. Additional Research – Floating Solar
Floating Solar - Benefits
Increasingly Feasible
Minimizes Property/Land Use
Reduces Evaporation
Controls Algae
Preliminary Assessment – Winchester and Trumble Road Ponds
Higher Capital Cost
Lower Energy Production Efficiency (non-tracking arrays)
Operational Challenges
Substantially Fluctuating Water Levels
Pond Maintenance Constraints
Routine Maintenance of Floating Array
