Rates and Tariffs

The Neighbourhood District Energy System (NDES) is a regulated public utility under the oversight of the British Columbia Utilities Commission (BCUC) that services residents of the Wesbrook community at the University of British Columbia (UBC). All of the rates charged by Corix are subject to review and approval by the BCUC using the same rate setting principles that are used in setting BC Hydro and Fortis BC rates, who are also regulated by the BCUC.

The NDES rate is inclusive of the majority of the costs associated with thermal energy delivery. Buildings connected to the NDES only pay for energy used and the pumping energy required to move it through a building. The end user is not responsible for paying fees associated with ongoing operations and maintenance of boiler equipment and hot water tanks, and does not have to pay into a contingency reserve fund for the eventual replacement of this equipment.

Below is a breakdown of what comprises Corix’s 10-year district energy rate at the NDES compared to that of electricity rates, according to BC Hydro’s Revenue Requirements Rate Application for 2015 and 2016*.

How are rates calculated?

All thermal energy is bulk metered by Corix through revenue grade meters and is billed to the strata as a lump value each monthly. Corix does not divide the bill between each strata lot user. 

All buildings connected to the NDES are billed in the following way:

The rate for energy is split into two distinct tariffs:

  1. The first tariff is the fixed component. The fixed component is billed based on the Gross Floor Area (GFA) of each individual building connected to NDES. It is represented on your actual bill by a $/m2 (or $/Sqft) charge. This charge covers off all of the “controllable” costs incurred by the utility in providing the service i.e – operations and maintenance, the utilities return on investment, financing costs for infrastructure, etc. This charge is the same every month.
  2. The second tariff is the variable component. The variable component is billed based on the amount of thermal energy used by a building in any particular month. It is represented on your bill by a $/kWh (or $/MWh) charge. This charge is based on the “uncontrollable” costs incurred by the utility in providing service i.e – Natural Gas and Electricity. 

How can I lower my energy bill?

Although energy costs are calculated per building, it is possible to effectively lower your energy bill by being conscious of your individual energy use habits. Here are some tips for energy conservation:

  • Avoid running hot water unnecessarily.
  • Leave thermostat temperatures at a comfortable range.
  • Avoid opening windows during the winter.
  • Wash clothes in cold water instead of hot water.

Corix has programmed all energy transfer stations (ETS), the equipment used to deliver thermal energy in each building, with the most efficient reset schedule possible, based on experience and historical data associated with each individual buildings performance. The Corix NDES will force the building to use all of available energy prior to using energy from the NDES, which ensures efficiency.
