A monthly mining update is dense with figures, but the useful signal sits in a few numbers that show how a public miner converts electricity into bitcoin. Canaan’s September 2026 update is a clean worked example: hashrate held steady while network difficulty climbed, production stayed flat, the treasury kept growing, and an energy-reuse plan moved from announcement to operation.
The headline number is 44 BTC mined during the month. That came against rising network difficulty, which steadily erodes what a fixed amount of hashrate can produce. Canaan kept its non-JV installed hashrate at 10.00 exahashes per second at month-end, while its joint-venture operations reported 4.87 EH/s installed and 4.18 EH/s operating. The gap between the two joint-venture figures is worth reading carefully: installed hashrate counts machines that could run, while operating hashrate counts machines actually energized, so the difference points to hardware that is offline or not yet plugged in. Holding installed hashrate steady as difficulty rises is the basic discipline that keeps monthly output from slipping.
Two numbers decide whether that output is profitable. Canaan reported a month-end average miner efficiency of 17.9 joules per terahash for its North America non-JV fleet, alongside an average all-in power cost of US$0.043 per kilowatt-hour. Fewer joules per terahash means less electricity spent per hash; a low all-in power cost widens the gap between what the miner pays to run hardware and what the market pays for the bitcoin it produces. All-in cost matters more than the headline electricity rate because it rolls in everything a site pays to keep machines running. The company also reported a 60.5% month-end average revenue split, a reminder that hosting and profit-sharing arrangements mean a miner does not keep every bitcoin its machines generate.
The balance-sheet figure shows the strategy. Canaan ended September holding 1,875 BTC, with production being retained rather than fully sold. Accumulating mined bitcoin is a wager on the asset’s long-term value, but it also concentrates exposure: revenue, operating costs, and now a growing treasury all move with the same asset. Chairman and CEO Nangeng Zhang framed the result as disciplined execution and noted that hashprice extended its recovery from August, pointing to improving mining economics.
The most concrete infrastructure detail is energy recovery. Canaan said its 8 MW Nordic district heating project is now fully operational, delivering recovered computing heat to roughly 2,800 homes, while a Canadian greenhouse heat-recovery project is moving toward deployment pending site inspections. Heat reuse does not change how much bitcoin a miner produces, but it can lower effective operating costs and turn waste heat into a second output in jurisdictions where energy policy rewards it. Miners pursue this partly for cost and partly because recovered heat is the clearest answer to what a mining facility contributes to the grid beyond demand.
Read a report like this in three layers. The operating layer — hashrate, difficulty, and production — shows whether the fleet is running as expected. The economics layer — efficiency, all-in power cost, and revenue split — shows whether the margin is healthy. The strategy layer — treasury growth and energy projects — shows what management is doing with the cash flow and the heat. On all three, Canaan’s September update reads as steady execution rather than a change in direction.
