Programme overview
Introduction:
District cooling operations training on plant, thermal storage, ETS and tariffs is a 10-day course for district cooling utility engineers, network staff and customer connection teams, ending with a District Cooling Network Operations and Tariff Plan. Schemes lose capacity and revenue when chiller trains run out of merit order, tanks charge at the wrong hours, low return temperatures strand plant and connection charges miss network costs. Nominees already operate, connect or bill district cooling customers and work through modelling builds on plant logs, hydraulics, meter data and tariffs. CoreConcept Training Center delivers this district cooling operations course.
Course Objectives:
- Dispatch chiller trains, distribution pumps and thermal energy storage against hourly load forecasts and time-of-use electricity prices
- Analyse chilled water network hydraulics, pressure zones and pumping energy to set differential pressure and supply temperature setpoints
- Specify, commission and audit energy transfer stations at customer buildings so they hold the contracted return temperature
- Diagnose low delta-T across the network from meter and ETS data and agree correction actions with customers
- Manage condenser make-up water from treated sewage effluent and other non-potable sources within water quality limits
- Build capacity and consumption tariffs and connection charges that recover plant, storage and network costs
Target Audience:
- Plant engineers responsible for chiller train dispatch, thermal storage charging and plant efficiency in district cooling utilities
- Network engineers responsible for buried chilled water pipework, pumping stations and pressure management
- Customer connection engineers responsible for energy transfer station design review, commissioning and handover
- Master-developer utility staff responsible for cooling load planning, plot connections and service agreements with the utility
- Commercial and billing staff responsible for meter data, tariff application and connection charge calculation
- Water and chemistry staff responsible for condenser make-up sources and treated effluent quality

Why Attend This Course:
- Deliver a District Cooling Network Operations and Tariff Plan to the head of utility operations and the commercial lead for approval
- Decide which chiller trains, storage tanks and pumps run each hour, and which customer buildings need ETS correction
- Avoid stranded plant capacity, excess pumping power and connection charges that fail to recover network extension costs
- Coach shift operators, connection engineers and billing staff with the dispatch schedule, ETS audit checklist and tariff model
Conclusion:
Back at work, the participant presents the District Cooling Network Operations and Tariff Plan to the head of utility operations, the commercial lead and the master-developer utility team. Management uses it to set the daily dispatch order for chiller trains and storage, agree return temperature targets and ETS corrections with customers, confirm make-up water sources and approve capacity, consumption and connection charges. After the first peak cooling season under the plan, the utility should compare plant kW per ton, network delta-T, make-up water use and revenue recovery with the plan and revise the measures that fell short.
Frequently Asked Questions (FAQ):
What should participants know before district cooling operations training on plant, thermal storage, ETS and tariffs?
Participants should already work on a district cooling plant, network, customer connection or billing team and be able to read chilled water trend logs and a basic tariff sheet. Anonymised plant logs, meter data or a customer agreement help during the modelling build days.
How does district cooling operations training differ from a building chiller plant course?
A building chiller plant course centres on chillers, pumps and controls inside one building. This course covers the utility: chiller trains serving many customers, thermal storage dispatch, buried networks, energy transfer stations, make-up water sources, metering and the tariffs that recover the investment.
Why does low delta-T matter so much in district cooling operations?
Low delta-T forces the utility to pump more water for the same cooling, so chillers and pipes reach their flow limits before their capacity limits. Capacity is stranded, pumping power rises and extra machines start, which is why customer agreements often set return temperature targets.
What do participants take back from district cooling operations training?
Participants take back a District Cooling Network Operations and Tariff Plan with a chiller train and storage dispatch schedule, an ETS audit checklist, delta-T recovery actions, a make-up water balance and a capacity, consumption and connection charge model.
