On May 11, 2020, Bitcoin's third halving cut block rewards from 12.5 BTC to 6.25 BTC, increasing the importance of power efficiency and economies of scale.

TerraHash's archived expansion plan describes standardized container mining pods connected to high-voltage substations, with target power-purchase agreement prices below $0.035 per kWh.

Seasonal hydropower surpluses offered lower-cost energy, with the archive citing wet-season rates as low as $0.025 per kWh for computing sites located near generation facilities.

Wind farms also experience periods of curtailed output. The project describes using interruptible mining loads to absorb electricity that otherwise could not be delivered to the grid.

New equipment included the Antminer S19 Pro, rated at approximately 110 TH/s and 29.5 J/TH, and WhatsMiner M30S/M31S series machines with materially improved efficiency.

The archived fleet plan describes a large-scale pre-order program and an intended improvement of more than 50% in average equipment energy efficiency to strengthen resilience after the halving.

The archived year-end report states that commissioning large-scale low-carbon facilities and installing S19-series hardware brought managed computing capacity above 500 PH/s in 2020.

With Bitcoin rising above $20,000 in the fourth quarter, the project positioned its hydro- and wind-powered facilities to participate in improving industry conditions.
