From solar panels on public buildings to new climate-control systems in city offices, Oceanside is continuing its efforts to modernize municipal infrastructure — and it’s now drawing national attention with a 2026 Smart 20 Award recognizing the scope of the effort.
Oceanside’s efforts to modernize city facilities and reduce energy use reached new milestones this winter, with major upgrades now completed and additional projects moving into construction, according to a city update released Feb. 13.
Among the latest developments, Oceanside was named a recipient of the 2026 Smart 20 Award by Smart Cities Connect, recognizing large-scale municipal projects focused on innovation and cross-sector collaboration.
The update outlined progress in the city’s comprehensive energy partnership with OPTERRA Energy Services, which began in 2024 and includes building upgrades, solar installations and infrastructure improvements. The project is designed to improve efficiency, strengthen reliability and lower long-term operating costs.
The city estimates the initiative could save about $26 million over 30 years, the update stated.
Planning and permitting work took up much of the project’s first year, including securing materials, hiring contractors and coordinating with San Diego Gas & Electric. A new electricity rate was approved for three municipal sites, helping reduce utility costs, according to the city. The Mission Lift Station energy storage system is now in final permitting, with installation scheduled for later this year.
Solar projects are also advancing.
A solar shade structure at the Oceanside Navigation Center is complete and awaiting approval to begin operating. Roofing and solar work is underway at City Hall North and South and the Civic Center Library. Additional installations are planned this year at the harbor, El Corazon Senior Center and the Robert Weese Water Filtration Plant, officials reported.
City facilities have also seen major heating and cooling improvements.
An energy audit identified 12 sites needing full HVAC replacement and 19 requiring upgrades. All of that work is now finished, including replacement of a 260-ton chiller serving the Civic Center complex. Smart thermostats have been installed at dozens of locations, allowing staff to monitor and adjust systems remotely.
Lighting upgrades have converted fixtures to energy-efficient LEDs at 30 city sites, including parks, fire stations and City Hall. Officials said the changes improve safety and allow some parks to remain open later in the evening. Reliability improvements have also replaced transformers at the water filtration and wastewater treatment plants to ensure consistent power.
Several community-focused programs were also highlighted.
Over summer 2025, the city hosted STEM camps and distributed 1,500 solar-themed kits. K-12 science books were donated to the public library, and internships were created for local college graduates. Other efforts include support for climate planning, senior center improvements and a pilot dune restoration project aimed at strengthening coastal resilience.
City officials said additional updates will be shared as new phases of the energy project move forward.
