Supported plan structures

Quick Overview

Our platform handles most common electricity plan structures, including standard rates, time-of-use pricing, seasonal variations, and solar feed-in tariffs. While we cover the vast majority of residential plans, there are a few complex structures we don't currently support to ensure our calculations remain accurate.

Detailed Breakdown

Below is a comprehensive list of what our system can and can't calculate. Don't worry if some of these terms sound complex - we'll explain each one further down.

Support Matrix

Plan Component	Structure	Status	Notes
Daily Supply Charge	Single fixed rate	✅ Supported	Standard daily connection fee
	Volume-based tiers	❌ Not supported	Rare in residential plans
Usage Charges	Single anytime rate	✅ Supported	Standard flat rate
	Volume-based tiers	✅ Supported	Different rates for usage volumes
	Seasonal rates	✅ Supported	Summer/winter variations
	Time-of-use (TOU)	✅ Supported	Peak/Off-peak/Shoulder
	TOU with volume-based tiers	✅ Supported	Different rates for different usage volumes
	Seasonal TOU	✅ Supported	Seasonal peak/off-peak
	Controlled load (flat)	✅ Supported	e.g., Hot water systems
	Controlled load (TOU)	✅ Supported	Less common but supported
	Demand charges	❌ Not supported	Coming soon
Solar Feed-in	Flat rate	✅ Supported	Standard solar credit
	Volume-based tiers	✅ Supported	Different rates by export amount
	Time-of-use	✅ Supported	Different rates by time of day
	Seasonal rates	❌ Not supported	Summer/winter variations
	Negative rates	✅ Supported	When exports might incur costs

Understanding Plan Components

Daily Supply Charges

This is your daily connection fee to the electricity grid.

What we support: Standard fixed daily rates

What we don't support: Plans where the daily rate changes based on how much power you use (these are quite rare)

Usage Charges

This is what you pay for the electricity you use.

What we support:

Standard flat rates
Rates that change based on how much you use
Different rates for different times of day
Different rates for different seasons
Controlled load rates (for things like hot water systems)

What we don't support: Demand charges (these are complex charges based on your highest usage

periods). They are becoming more and more common, so support for this is coming soon.

Solar Feed-in Tariffs

This is what you get paid for sending solar power back to the grid.

What we support:

Standard flat rates
Rates that change based on how much you export
Even negative rates

What we don't support: Seasonal rate variations (e.g. winter rate / summer rate)

What This Means For You

If you encounter a plan that has an unsupported structure, we'll exclude it from our calculations rather than risk showing you incorrect savings figures. We believe it's better to be upfront about what we can't calculate than to make assumptions that might mislead you.

Future Developments

We're constantly working to support more plan structures. Demand charges are next on our list, and we're evaluating other complex structures based on user feedback and market changes.
