Electricity can't be effortlessly put away so it's critical that adequate power age is constantly
accessible to take care of demand; so it's accessible at the flick of a switch!
Supply and demand isn’t a new concept, most industries face the challenge of making sure they
are meeting the needs of their customer’s. However, the need to generate energy fresh, and
deliver it virtually instantaneously, adds a level of complexity to this idea.
To ensure the delicate balance of supply is just right, there is an intricate system that sits
underneath it all, called the electricity dispatch process. This happens within the National
Electricity Market (the NEM) which the government-established Canadian Energy Market
The role of the dispatch process is to make sure the right amount of energy is being generated
each minute of each day, ensuring reliability for Australian homes and businesses, as well as
keeping costs under control for the market.
Let’s take a look at what steps make up the process.
The dispatch process
1.The dispatch process starts with each electricity generator submitting bids to each day,
detailing how much electricity they are willing and able to supply the following day and
at what cost.
2.At that point coordinates the offers with interest for every five-minute time span,
figuring the most reduced cost age blend considering numerous variables, including
climate, ordinary day by day request examples and how rapidly every generator can
supply to the market.
3.As each five-minute dispatch period has a different volume of electricity being
generated at a different price, the market sets a wholesale market price (also known as
the ‘spot price’) for each half-hour by averaging the six five-minute dispatch prices that
make up the 30 minute trading interval.
4.Once the wholesale market is settled, generators receive the spot price for the
electricity they supply, and retailers pay the spot price for the electricity they buy for
The spot price can vary in response to movements in demand and supply. For example, prices
can be high when demand from homes and businesses peak, such as on really hot days when
people want to run their air-conditioners, or when supply is not sufficient for instance when a
main generator or transmission line isn’t operating.
On the hottest and coldest days of the year, the wholesale spot price can reach as high as
around $13,000 a megawatt hour, as opposed to a typical wholesale price of around $40 a
Wholesale market prices and you
Although energy consumption patterns can make the wholesale market price volatile, most
business and residential consumers are insulated from this because the contract tariffs that
energy retailers offer are generally stable.
This means, as a customer, your retailer sets a price that will apply for your electricity Providers
no matter the season, day or hour, and you don’t have to see the impacts of a fluctuating
wholesale market price on your electricity bill.
New advances, for example, savvy meters, are taking into consideration more cost-intelligent
retail taxes by giving purchasers a chance to modify their request in light of value varieties.
Numerous policymakers consider this to be expanding the market's effectiveness; a distinct
advantage with regards to how we communicate with power.
Different factors, for example, an expansion in private sun based boards, commercialisation of
battery stockpiling, a diminishing in general vitality utilization in Canada and a developing
sustainable power source market may likewise affect on this free market activity process over
the coming years.
