Site C, a new 1 MW dam, is under construction. Wind capacity grew from 0 to MW between and Four wind farms were built between and , most of them under the BC Hydro Standing Offer Program initiated in The B. Some biomass plants are built on the sites of idle sawmills. This table shows BC's electric capacity and generation from renewables in and Expected to be completed and in service by , Site C will provide 1, megawatts MW of capacity, and produce about 5, gigawatt hours GWh of electricity each year — enough energy to power the equivalent of about , homes per year in B.
Unplug This Blog! How BC Hydro powers B. The Mica Generating Station north of Revelstoke is currently undergoing construction to add two new generating units for an additional 1, megawatts of capacity. A complex system needed to deliver electricity from our facilities to your home Posted by Tanya Fish Our electrical system is vast and complex.
Turning water into electricity The BC Hydro system generates over 43, gigawatt hours of electricity a year, more than 90 per cent of it through hydroelectric generation. When the water is released from the reservoir, it travels through the dam and is converted into kinetic energy — energy produced by motion — by flowing through a an enclosed pipe known as a penstock that funnels water to turbines The flowing water then turns a turbine, which is connected to a generator.
As the turbine turns, the generator converts that kinetic energy into electric energy. A step-up transformer then increases the voltage of the electric energy produced by the generator so that transmission lines can carry it efficiently over long distances. Peace and Columbia rivers power a province Our Peace Northern and Columbia systems are responsible for the majority of BC Hydro's electricity generation. Transmission and distribution The southwest region of B. Meeting increased demand in the winter season Colder temperatures and fewer daylight hours increase electricity use across the province in winter.
More turbines, a new dam, will help meet future demand To keep up with B. This power is delivered using an interconnected system of over 73, kilometres of transmission and distribution lines. So how do we generate this power? The process begins before electricity even reaches customers. The steps to generating electricity from a dam and how it is transported are outlined below.
Hydroelectric dam There is potential energy stored in a water reservoir behind a dam. It is converted to kinetic energy when the water starts flowing down the penstock, from the dam. This kinetic energy is used to turn a turbine.
