The Bitcoin Miner That Decided It Was Really an Energy Company
MARA runs roughly 1.9 gigawatts of computing across four continents, holds more than 50,000 bitcoin, and now wants to sell you the cooling tanks and energy software behind it all.
Digital Power Optimization, Inc.
Digital Power Optimization (DPO) is a New York-based energy services company that builds and operates 'power-first' flexible data centers at renewable power plants. Its on-site data centers - running bitcoin mining and AI workloads - consume electricity only when it is curtailed, wasted, or undervalued, then curtail during peak demand so power can be sold back to the grid. The model lets hydro, wind, and other generators capture over $100/MWh from otherwise stranded power while helping stabilize the grid.
Emulate Energy
Emulate Energy is a Lund, Sweden cleantech company that builds white-label software turning everyday household devices - EV chargers, heat pumps, home batteries and solar inverters - into a coordinated, grid-ready fleet. Its platform lets utilities, retailers and grid operators connect, control and monetize distributed energy resources: cutting household bills, shaving grid peaks and unlocking flexibility-market revenue without asking customers to change tariffs or behaviour. Founded in 2020 on control-theory research from MIT and Lund University, Emulate runs live programs across Europe and the US.
