Healthcare — hospital energy management
Hospital Energy Monitoring & Electricity Cost Calculation
Energy monitoring for a public hospital with rooftop solar — power-meter data in Siemens Energy Manager PRO, with dashboards of use per building and the electricity cost calculated from it.
- Role
- Energy monitoring set-up and electricity cost calculation
- Company
- P.A.M Engineering & Automation
- Period
- Jan 2024 – Dec 2024
- Platforms
- Siemens Energy Manager PRO · Siemens SENTRON PAC5200
Highlights
- Electricity use shown per building instead of one number on the utility bill
- Electricity cost calculated from the measured energy, not estimated
- Dashboards the hospital's facilities team can read without engineering software
Problem
A large public hospital, which was also installing rooftop solar, wanted to know where its electricity went and what it cost. The utility bill gave one figure for the whole site; nobody could say which building used what, or what that use was costing.
My role & scope
My part was the monitoring and the money: setting up energy monitoring in Siemens Energy Manager PRO from the SENTRON power meters in the distribution boards, and calculating the electricity cost from the measured energy.
Approach
Measured, not estimated
The PAC5200 meters in the distribution boards report voltage, current, power and energy for each building. Energy Manager PRO stores those readings and shows them as dashboards of use per building, with trends and gauges.
From kWh to baht
The energy readings are turned into an electricity cost, so the facilities team sees what each building’s use is costing, not only how many kilowatt-hours it took.
Delivery
- Energy monitoring configured in Energy Manager PRO for the meters on site
- Electricity cost calculation from the measured energy
- Walk-through with the hospital’s engineers at handover
Result
- Electricity use and cost visible per building instead of one monthly figure
- A measured baseline for the hospital’s energy-saving work and its solar plant
