This is a key distinction. The electricity supplier is the company you pay your bill to; they purchase electricity from generators and sell it to you. You can often choose your supplier to find the best rate.

The electricity distribution company, on the other hand, is the company that owns and operates the physical infrastructure that delivers the power to your home or business. They are responsible for the utility poles, overhead lines, underground cables, and transformers in your area. You do not get to choose your distribution company. When a power outage occurs or if you see a downed power line, you should always contact your distribution company's emergency number.
