Real day-ahead prices for Germany from SMARD and Energy-Charts. A simulated 5 MW research cluster where 35% of jobs can wait up to 12 hours.
Earliest new grid connection
Syna, the grid operator in Frankfurt's west, can only promise new connections beyond 2032.

In 2025, Germany had so much wind and solar that producers paid consumers to take power for 573 hours.

Spot the jobs that can wait
Researchers already tell the cluster when they need results. Kenwatt reads that deadline and separates urgent work from work that can wait.

Jobs that can wait
Whether a site buys power at market prices or at a fixed price, Kenwatt finds money in the same workload. Figures for a 5 MW cluster where 35% of jobs can wait up to 12 hours, replayed on every hour of 2025.
Already buying at market prices
Run waiting jobs in the cheapest hours
Every day, tomorrow's hourly prices are published at noon. Kenwatt plans each waiting job into the cheapest hours before its deadline.
a year, 6.3% of the energy cost
On a fixed price today
Stop paying for protection you don't need
Fixed-price contracts carry a risk premium, historically around 10% over the market average. It buys protection from price spikes. A cluster that can step around the spikes can switch to market prices and keep that money, plus the savings on the left.
Next step
A faster grid connection
Once a site has a record of keeping agreed limits, that flexibility becomes something to offer its grid operator. German law allows early, flexible connections for sites that accept limits at peak times (§ 17 (2b) EnWG). We're validating this with grid operators in Rhein-Main before promising it to anyone.
See what runs now, what waits, what it saves, and whether the site is keeping its promise to the grid. Your rules decide. Urgent work never waits.

Watch-only first
For the first month Kenwatt only observes, then shows what it would have saved. You decide if it ever acts.
Uses Slurm's own controls
Holding, releasing, and power-capping jobs are built into Slurm already. Kenwatt adds no new hardware.
Research data stays put
Kenwatt sees job sizes, deadlines, and power, never the data or code inside a job.
Your rules, enforced
Urgent queues never wait, deadlines are never missed, and the cluster is never left idle below your floor.
University and research computing centers
Big shared clusters full of batch jobs with deadlines in days, not minutes. Our first pilots start here.
AI labs and GPU clouds
Training runs and batch inference can wait for the right hour. Live inference keeps running as it is.
New data centers waiting for power
Proven flexibility makes a flexible connection agreement possible, so the site can open before the grid upgrade is done.
One month on your cluster. Nothing moves. At the end you get a report of what Kenwatt would have saved and how much flexibility your site could offer the grid.
