Reports

Each report asks one question of the tariffs US utilities have filed, runs the same households through every plan to answer it, and publishes the method and the limits alongside the result. Where the answer was not the one we expected, we say so.

Is the electricity plan you were put on the cheapest one?
Every residential plan at each utility, priced for one household: how often the default plan is already the cheapest, and what moving is worth where it is not.
Why a small apartment pays more for each kilowatt-hour than a family house
The fixed monthly charge on the default plan at each utility, and how it makes a small household’s price per kWh higher almost everywhere — with the tiered exceptions.
Why is the July electric bill so much higher? Mostly not because of the rate
The same air-conditioned house priced every month: how much of the summer jump is the rate and how much is usage, and where summer electricity really costs more.
When are peak hours for electricity? There is no national answer
Every residential time-of-use plan’s peak window side by side: how many different windows there are, how early they start, and how few leave weekends alone.
