1 BACKGROUND
• On January 28, 2020, the City Council directed
City staff to pursue an energy audit.
• In 2021 AECOM completed a detailed feasibility
study for the City of Santa Rosa to help the city
identify cost-effective opportunities for reducing
Greenhouse Gas (GHG) emissions and improving
the resiliency of the City’s operations.
2 BACKGROUND
• On September 22, 2020, the Transportation and
Public Works Department briefed the Climate
Action Subcommittee on the status and details
of the proposed study. The Subcommittee
provided comments and supported the
Transportation and Public Works Department in
bringing this proposal to Council.
• On December 1, 2020, Council approved the
contract with AECOM to perform an energy audit
on general fund buildings.
3 BACKGROUND
• On October 13, 2021, the Transportation and
Public Works Department and Santa Rosa Water
briefed the Climate Action Subcommittee on the
final report completed by AECOM. The
Subcommittee provided comments and
supported the Transportation and Public Works

possible funding sources to City Council.
4 MSCN BUSINESS PLAN
• AECOM Will provide a complete plan to analyze:
• Energy Efficiency
a. MSCN Packaged Unit Replacement and HVAC Upgrades
b. MSCN Chiller Replacement
c. MSCN Boiler Replacement
• Solar PV Systems: The MSCN consists of 8 facilities. The AECOM feasibility study identified the MSCN garage as the most feasible location for the implementation of solar PV Systems. AECOM identified two options for this site: either a canopy design for the car parking spaces or a [canopy/ground mount/roof mount?] system for the bus parking. Both options will be evaluated in the business plan analysis.
5 MSCN BUSINESS PLAN CONT .
• Battery Storage Systems: The City is interested in
installing a battery storage system at the MSCN
facility. AECOM conducted a feasibility study of
the battery storage system as part of the
complete microgrid system feasibility study.
AECOM will consider the battery storage system
in the business plan analysis.
• Electric buses and charging infrastructure
deployment for the MSCN facility
6 SOLAR PV FEASIBILITY
STUDY
• Santa Rosa Water is interested in due diligence review and feasibility determination of the following 2019
Energy Optimization Plan identified solar PV and floating solar PV systems concepts:
• A 320kW system mounted on a new truck-port structure
- Utility Field Operation
• A 1,257kW system mounted on four new truck-port
structures
• A 134kW system on existing rooftop structure – Waste
Transfer Station
• Floating PV at three (3) Laguna Treatment Plan ponds (B, C and D)
7 RECOMMENDATION
It is recommended by the Transportation & Public Works
Department and Santa Rosa Water that the Council, by
