A Tour of Hydro Ottawa's TOU Portal

Hydro Ottawa is slowly and finally starting to roll out TOU to its customers now, and here is a sneak peek at what their Internet portal looks like. (Click on the images for a larger view).
In the upper right corner of each data page, are buttons to print, or download the displayed data in Excel or PDF formats. This allows the customer to store long term data or run other analysis.

The home page shows some quick overview graphs, including the last recorded day's usage.

The hourly page shows an hour-by-hour view of electricity usage, color coded to match the off, mid, and on-peak periods. The high contrast option, turns all the graphs into an unpleasant black and white scheme, which must be an accessibility function.

The daily graph shows a summary of each day's electricity consumption, along with user selectable total daily cost or consumption.

Much like the daily graph, the monthly graph shows each calendar month's total data.

The billing period graph shows a breakdown of usage for the period covered by any of your previous bills. You can compare one month to the other using the drop down boxes above the graph.

The TOU calculator is interesting, as it allows the customer to use the mouse and pull the three bars up and down to play "what-if" scenarios, then shows the results on the right hand side.

The tiered-vs-TOU page allows you to see what you would pay under the old regulated price plan, vs. Time-of-Use, vs. any arbitrary third party contract. This customer, as an example, is paying slightly more under TOU than the old regulated price plan. If an option becomes available in the future for customers to opt in or out of TOU rates, this page is a valuable tool to determine which is the better deal.

The blue bar showing the value of a third party contract entered at 8.0 cents/kWh does NOT include the Global Adjustment, which is currently running 4.3 cents/kWh!
