Dyson Sphere Program Power Grid explained
In Dyson Sphere Program, you need to harness energy of various kinds to power your factories. A power grid, at its core, is amazingly simple. All you need is:
A building that generates power (such as a Wind Turbine);
A building that consumes power (such as a Mining Machine);
A building that connects the generators to the consumers (such as a Tesla Tower);
(Optional) A building that stores energy (such as an Accumulator).
Every power-generating building (like Wind Turbines), and every range-extender (like Tesla Towers) produce a circle of energy around them. A building is considered powered if its central tile is covered by one of these circles. It s best to build big blocks of power generators away from your production buildings, and then connecting one to the other with lines of Tesla Towers.
