Demand expected to grow up to 50 per cent
B.C.'s population and economy are growing and so is our need for electricity. Over the next 20 years, the demand for electricity in B.C. is expected to grow by as much as 50 per cent – the majority of it in the Lower Mainland.
Links between power generation and B.C.'s populated area
The ILM project will expand the capacity of the essential transmission system that brings power from generation resources in the north and southern Interior of the province so that it can continue to deliver clean and reliable energy to customers in the Lower Mainland and on Vancouver Island.
Built in the early 1970s, this system is reaching the limits of its capacity – particularly during the winter months when electricity use peaks.
When the existing 500 kilovolt (kV) transmission line was constructed in the 1970s, additional right-of-way was acquired at that time in anticipation of future demand.
Benefits and opportunities
By ensuring the most efficient transfer of electricity, the ILM project will reduce the amount of energy that otherwise would be lost on the transmission system – enough energy to supply about 80,000 homes per year.
During its three years of construction, the ILM project will create economic opportunities for local vendors and suppliers and generate about 450 person-years of employment.
