| This group consists of companies in North American
Industrial Classification System Sub-Sectors 211 (Energy), 212 (Mining),
331 (Smelting), and also specific Industries 324 110 (Petroleum
Refineries), 325 110 (Petrochemical Manufacturing) and 486 210 (Pipeline
Transportation of Natural Gas). The stations for these industries
are scattered across Canada. The stations are often relatively large
- the largest has a capacity of 912 000 kilowatts.
There are 53 stations in this group, of which 17 are hydro and
36 are thermal. The energy industry almost invariably uses natural
gas as the fuel for its plants. The generating stations for mining-related
industries in this group vary in their fuels - generally those in
more remote areas use diesel fuel.
The largest plants in this group are the seven operated by the
aluminum industry. The process for making aluminum needs large amounts
of electric power and, consequently, the industry has almost invariably
located where it can develop or make use of large hydro sites, even
when these might be in a relatively remote area. |
