Southern California healthcare data center cuts energy use 26%

A Southern California healthcare provider reduced data center energy consumption by 26% and saved more than $1 million a year after an ONSITE Utility Services upgrade funded through Energy-as-a-Service. The project lowered the facility’s PUE from 1.73 to 1.54 without upfront capital cost.

Why it matters: - The upgrade cut operating costs at a healthcare data center that was spending more than $4.1 million a year on electricity. - Lower energy use and a better PUE can free up budget for expansion and reduce strain on aging infrastructure. - The project delivered savings with zero capital cost, which matters for facilities that need efficiency gains without new debt.

What happened: - ONSITE Utility Services announced that a regional healthcare provider in Southern California reduced annual data center energy consumption by 26%. - The provider saved more than $1 million a year after the efficiency work. - The facility’s PUE improved from 1.73 to 1.54. - The upgrade was funded entirely through Energy-as-a-Service. - The project was completed with no upfront capital expense from the provider.

The details: - ONSITE reviewed 12 months of utility bills and the facility’s mechanical equipment before conducting an onsite audit. - The plan targeted the existing HVAC equipment and incoming power quality. - Smart controls were added to the chillers and rooftop units serving the data space. - Compressors and supply fans were converted from fixed-speed to variable-speed operation without sacrificing output. - A nano-polymer coating was applied to evaporator and condensing coils to close microscopic openings and protect the components from corrosion. - Power optimization equipment was installed at all four switchgear locations feeding the facility. - The power equipment balanced voltage across all three phases and reduced KVAR. - Annual electricity use fell from 23,678,034 kWh to 17,427,412 kWh over a year. - The provider reported fewer service calls on its HVAC equipment. - ONSITE said the project preserved $2.83 million in upfront capital expense. - The provider retained $29,336 in monthly savings at zero capital cost. - ONSITE Utility Services says it designs, funds and implements energy efficiency and infrastructure upgrades for commercial, industrial, healthcare and municipal facilities nationwide. - The company says its Energy-as-a-Service platform covers 100% of capital, equipment, installation and maintenance for qualifying projects, with zero capital cost and zero debt to the client. - ONSITE says customers pay a single monthly service fee that is lower than prior combined energy and maintenance costs. - The company says customers retain 100% of ongoing savings once the service term ends. - More information is available in the company's announcement.

Between the lines: - The project points to a broader trend in healthcare facilities: energy savings can come from controls, tuning and power-quality improvements rather than full equipment replacement. - The zero-capital structure makes the economics easier for providers that want lower bills but cannot justify large upfront spending. - The reduction in service calls suggests the work may have improved equipment reliability as well as efficiency.

What's next: - ONSITE said the savings can help fund future expansion. - The company is positioning the same Energy-as-a-Service model for other qualifying facilities nationwide. - The healthcare provider is now operating the data center at a lower energy cost base, which should continue to support annual operating savings.

The bottom line: - A targeted efficiency retrofit cut energy use, lowered PUE and delivered seven-figure annual savings without upfront capital spending.
