About KilowattHQ
Last updated 21 October 2026
KilowattHQ publishes US electricity price data in a form you can actually use. The underlying figures are public, released every month by the U.S. Energy Information Administration, but they arrive as bulk data files that are close to unreadable unless you already know what you are looking for. This site turns them into something a homeowner can answer a question with in ten seconds.
What is here
- Current residential, commercial and industrial electricity rates for all 50 states and DC
- The average electric bill in each state, calculated the way EIA calculates it: total revenue divided by customers
- Monthly price history for each state — a five-year chart on the page, and the full series back to January 2001 as a free CSV download
- A national ranking, updated whenever EIA publishes
- Calculators that turn a rate into a dollar figure: monthly bill, appliance running cost, EV charging, solar payback
Who runs it
My name is Yasir Siraj. I work as a senior software engineer at a software company, building system integrations, FinTech platforms and database-heavy applications — mostly in Java, PHP and SQL Server. You can check my background on LinkedIn.
KilowattHQ is a personal project, built and maintained by me alone in my own time. It is not connected to my employer in any way.
I should be straightforward about something: I am not an energy analyst, and I do not live in the United States. I am a developer who builds data systems. What I bring to this site is the part that decides whether the numbers are right — reading the EIA feed correctly, normalising its units, weighting the national average by sales volume rather than averaging 51 states equally, and keeping all of it current without anyone having to remember to press a button.
Everything on this site traces back to a single public source. Nothing here is my opinion about American energy policy, and where the data has limits I say so plainly on the methodology page rather than hoping you will not notice.
Why I built it
I went looking for what a kilowatt-hour costs in a particular US state and found the answer surprisingly hard to reach. The data is public and free, but the sites presenting it tend to bury the number: several clicks through country, then state, then city, past a form asking for your ZIP code and email before showing you anything useful.
That struck me as a solvable problem rather than a hard one. The figures were already free. What was missing was somewhere that simply showed them — one page per state, the current rate at the top, the five-year trend underneath, and a calculator that turns it into the number people actually care about, which is what their bill will be.
So that is what this is. No account, no email, no ZIP code, no clicking through four levels of menu. The rate is the first thing on the page.
How it is funded
At the moment it is not funded at all: there is no advertising on the site. The plan is to carry display advertising later. When that starts, ads will be clearly separated from the data and will have no influence over what the figures say, and the privacy policy will be updated before the ads go live, not after. If a state has expensive electricity, the page says so. Nobody pays to appear here and no figure on this site is sponsored.
Corrections
If something here is wrong, tell me and I will fix it. Data errors get corrected the same week — that is the part I can promise, because it is the part I control. Get in touch.
