Electricity supply options update
We continually monitor generation options potential, costs and the technical capabilities of different technologies in B.C., and periodically we update our inventory information for planning purposes.
In 2015, we updated cost and technical information for the following generation options: wood-based biomass, municipal solid waste, onshore wind, run-of-river, natural gas-fired generation, geothermal, wave, tidal and solar. For the rest of the generation options we updated costs to account for inflation.
Updating our inventory through industry engagement and utility collaboration
For the latest updates, our technical staff collected and reviewed new data – with input and feedback from industry experts, consultants, and others with technical expertise – to ensure the information is accurate and up to date. Learn more about the resource characterization engagement process that took place in 2014 and 2015 by viewing the Technical Engagement Summary Report, or the specific meeting notes and presentations.
For this process, we collaborated with FortisBC on this shared inventory dataset. A shared dataset supports our respective planning processes, and creates efficiencies as well as consistency during review processes.
Results of the inventory update
An overview of the 2015 update is available in the Results Summary. The costs presented ($2015) were estimated at the point of interconnection.
For the first (lowest cost) ~5,000 GWh of resources, we also calculated the adjusted unit energy cost to show the cost of delivering this energy to the Lower Mainland. This ~5,000 GWh of resources was determined to be onshore wind, of which the weighted average Unit Energy Cost at the Point of Interconnection is about $80/MWh. The adjustments required to arrive at the cost of this energy delivered to the Lower Mainland ($100/MWh) are provided in this document [PDF, 19 KB].
