Demand Flexibility

A reliable energy buyer
that travels to the source.

Mobile Bitcoin mining containers deployed at sites with surplus renewable generation. Short- to medium-term agreements, instant curtailment, no permanent infrastructure.

The Problem

Managing surplus renewable energy is a structural challenge

Renewable energy capacity is being added faster than grid flexibility can keep up. The result is energy that gets curtailed, sold at a loss, or priced negative — value that simply disappears.

📉

Negative Pricing

Renewable grids regularly see hours of negative electricity prices — and the trend is rising. Producers effectively pay for energy to be consumed.

💨

Curtailed Renewables

Wind and hydro generation is regularly switched off because the grid cannot absorb it. Clean energy wasted means clean investment wasted.

🔌

Grid Bottlenecks

Transmission constraints prevent surplus from reaching demand centres. Local overproduction has no outlet — existing industries cannot absorb sudden surges.

🏭

No Flexible Buyers

Traditional industries need long-term, stable contracts. Nobody can absorb a 6-month window of 1.25 MW on short notice — until now.

The Solution

A buyer that moves to the energy

Kefos operates a fleet of hydro-cooled Bitcoin mining containers. When you have surplus energy, we bring a container to your site, connect to your grid, and start purchasing. When you need the capacity back, we ramp down instantly — or relocate entirely.

  • Short-term, flexible agreements — no long-term PPA required. We work on windows from months to years.
  • Instant curtailment — our load drops to zero in seconds, on your signal or ours. Faster than any other industrial process.
  • We handle the complexity — hardware, operations, monitoring, and maintenance are entirely Kefos' responsibility.
  • Clean credentials — we operate exclusively on renewable energy. Zero carbon, zero compromise.

How a deployment works

1
You identify surplus A surplus window opens — hydro spill, wind peak, low overnight demand. You contact Kefos.
2
We agree terms Energy price, duration, load level, and interruptibility conditions — agreed quickly on a standard framework.
3
Container arrives We transport, install, and commission the container at your nominated site, near your substation infrastructure.
4
We buy your energy Mining runs continuously. Load modulates in real time to your grid signals. You receive payment per kWh consumed.
5
Deployment concludes When the window closes or you need capacity back, we decommission and relocate. The site is returned to its prior condition.
Why It Works

Four properties that make this operationally viable

🧩

Modularity

Each container is a self-contained unit. Scale up by adding containers, scale down by removing them. Match the load precisely to available generation — no overbuilding required.

🚛

Mobility

Containers are transported by road, sea, or rail to wherever surplus exists. Remote hydro plants, coastal wind farms, isolated substations — geography is not a barrier.

🎛️

Flexibility

Load ramps from zero to full in minutes, and drops to zero in seconds. Acts as a real-time demand sponge — absorbing fluctuations and supporting grid frequency stability.

Exportability

Bitcoin is a digital export. Value leaves your site via a data link — not roads, ports, or aircraft. No physical product to ship. No logistics cost on the output side.
