INNOVATION May-June 2017

Retrofit reduces energy use and costs The District of North Vancouver had planned to install a biomass boiler to provide heating to the Karen Magnussen Community Recreation Centre. Under the leadership of the district’s energy-management team and SES Consulting, the district instead chose to reduce the building’s energy consumption through efficiency. The resulting project is on target to reduce the building’s energy consumption and greenhouse gas emissions by 60 percent. Key features include a full lighting upgrade, new controls to optimize the HVAC system, and a low- energy ceiling to reduce the load on the ice plant. The new advanced heat-recovery system captures waste heat from the pools and arena to virtually eliminate the load on the existing boilers. The centre, built in 1974, is now almost as efficient as the district’s new-construction recreation centre.

Pattern Energy Group’s development of the Meikle Wind Energy project in BC’s Peace River Region included the 230-kiloVolt transmission line for their facility to the point of interconnection, approximately 23 kilometres west of BC Hydro’s Tumbler Ridge substation and 36 kilometres from the Sukunka substation. The maximum total power injection from Meikle Wind Energy is 180 megawatts—enough to power 54,000 homes. SNC-Lavalin’s Power Group was contracted to produce the design and provide project and construction management services for a new terminal to connect the energy-generating facility to BC Hydro’s grid. The transmission lines were Project improves energy reliability, lowers power costs

interconnected through the new 230-kiloVolt ring bus Meikle Terminal substation at the point of interconnect. The new substation consists of 230-kiloVolt breakers in ring bus configuration, station service transformers and a diesel generator. The switchyard includes a spare area for one power distribution transformer and one 25-kiloVolt feeder. APEGBC members: Raafat A.
