Knowledge Centre for Business & Industry

​In Ontario, if you are a business that pays more than $2,000 a month for electricity, you pay the wholesale market price rather than time-of-use prices.  Knowing which rate you pay, however, is just the first step towards becoming an effective energy manager.

It is equally important to consider factors such as how the wholesale market price changes throughout the day. Or what d​​​emand charge means on your electricity bill. Discover which energy-saving initiatives are available — and how new technologies and best practices can help keep energy costs in check.

Clearly, the more knowledge you have, the more effectively electricity costs can be managed. This section offers an introduction on how to build an energy management knowledge base for your business.
