​Reducing your Global Adjustment Costs

The Global Adjustment (GA) is a line item charge on your monthly Ontario electricity bill. The GA accounts for the difference between the market price and rates paid to regulated and contracted generators as well as conservation and demand management programs. The GA charge has become one of the highest component charges on your electrical bill.

​Our estimate for 2016 calendar year is a total GA of approximately $10 Billion for Ontario, resulting in an average cost of approximately $450,000 per MW (measured during the top 5 Ontario peaks for Class A consumers). In other words, if you can reduce your net load through curtailment or on-site generation by 1 MW for all 5 Ontario Peaks, then you will save $450,000 for the year1. Our services are designed to help you determine when those peaks will occur so you can take steps to avoid them.

Our Notification Service

​Sygration and Rodan Energy provide a service that uniquely addresses the needs of Ontario Class A consumers by reducing their GA costs. Having based our service on the needs demanded by Class A consumers, we have created an innovative, customer-friendly process to will alert you to when these peaks occur. Our philosophy is centred around the fundamental understanding of the market dynamics in what drives peaks during a peak day.

Our Approach

Our service follows an outward-focused methodology that understands the dynamics of the Ontario market and the factors that determine what the peaks will be well ahead of the peak season. As we approach a day that is at risk of becoming a peak, we take a very critical view on demand forecasts and factor in items such as past forecast accuracy, expected reactions of Dispatchable Loads and Class A ​Consumers (including our own customers), as well as changes in weather that could shift the peak hour. We identify the hours at risk along with different thresholds of confidence, and provide a statistical probability of how likely a peak will stay in the top 5. This gives our customers the information they require to determine if curtailment action is appropriate, and to what degree. The customer is the ultimate decision maker, so we ensure they are receiving our latest recommendations and are available for consultation whenever required.

A main pillar of our service is the education we provide to our customers to ensure they understand our methodology for setting curtailment thresholds, that the service aligns with the customer’s implementation strategies, and that the factors that impact the GA peak demand during an active day are understood. We provide this through a combination of reporting, group and personal communications.

In addition to personal training that ensures new customers understand the use of the tools and reports, we discuss how best these customers can implement our alert notices into their own curtailment/displacement strategies. We also schedule regular on-line webinars with all customers to discuss our expectations and risks as we approach the Summer and Winter peak periods.

​​Notices & Alerts

Customers receive regular reporting well in advance of the peak season occurring. As we approach a peak day, alerts are sent that identify those hours at risk of becoming a peak. In these alerts we consider such factors as IESO forecast accuracy, early weather formations and the impact of Class A consumers resulting in a shifted peak. We also provide separate risk bands (low, moderate, and high) that allow customers to decide how to implement our curtailment recommendations across different processes that may have different scheduling requirements or risk tolerances.

Monthly reports sent by email are used to communicate our initial demand threshold ̶ the sweet spot where we expect all peaks to exceed without requiring excessive curtailments ̶ and to identify peak expectations during that period so customers can prepare if necessary. These reports identify the likelihood of peaks occurring and when they will likely occur so customers have ample time and can take the appropriate steps to have their business processes ready for a peak.

Day ahead reports are issued the day before a potential peak day, and provide enough notification to prepare for the next day’s events. This gives customers notice prior to a possible peak day indicating the hours most at risk of becoming a peak.

Hours at Risk Table

Day at Hand report are issued the morning of a peak, and provides further detail of the day’s peak expectations These use more up-to-date forecast data for the target day, and confirms the Day Ahead notice with expected peak times and durations.

Peak Day Updates provide the customer with information regarding any anomalies during the peak day and gives expectations of changes in peak hours or duration of peaks throughout the day. Alerts are sent by email and are displayed on the front dashboard so they are clearly visible and informative.

​​Sygration Tools

As we enter a period of potential peaks, we ask that all customers turn to the Sygration Dashboard to monitor Ontario Demand, system events, the real-time Demand Forecast Error, as well as our alert messages. The Dashboard has been in use for over 10 years and is relied upon by over 60 companies to monitor the dynamics of the Ontario electricity market in real-time.
