Grid Power is an energy system added by Extra Utilities 2.
In addition to, or instead of Redstone Flux, some Extra Utilities 2 items require Grid Power. Unlike other energy systems, Grid Power is player-specific, wireless, range-less and cannot be stored. Any generators placed will be linked to the player that placed them and contribute to that player's Grid Power pool. Grid Power can be shared with other players using the Power Sharing Command.

Operation
GP generators add to player's pool of power. Some GP consumers use a fixed amount of GP, e.g. the Ring of the Flying Squid. In other consumers, e.g. the Resonator, consumption is variable. GP consumption is summed and if consumption is greater than production, everything stops. For example, a player has ten Lava Mills, generating a total of 20 GP. The Resonator draws a variable amount of GP, up to 8 GP. If the player crafts a Ring of the Flying Squid (16 GP), their total power requirement is now 16 + 8 = 24 GP. If the Resonator is not being used, the Ring of the Flying Squid works normally. However, crafting some Stoneburnt draws up to 8 GP. As soon as the Resonator tries to draw more than 4GP, the Resonator and the Ring of the Flying Squid cease to work. If the player was in the air at that moment, they might come to an abrupt end.
Chunkloading
Due to the nature of GP power, players will want to keep chunks with generators loaded. This is absolutely essential for devices such as the Angel Ring.
Generators
Starting Options
The Manual Mill generates 15 GP. It is operated by right-clicking the mill and continuing to look directly at the mill. Turning or walking away from the Manual Mill will stop power generation.
The Solar Panel generates up to 1 GP during daylight hours, requires line of sight to the sky and is affected by rain.
The Manual Mill is recommended over the Solar Panel as it consistently generates more than the 8GP required to run a Resonator. It need only be run for a few minutes to cook enough Stoneburnt to make a few Water Mills or Lava Mills.
Second Tier
Lunar Panels are the night time counterpart to the Solar Panel and generate up to 1 GP during the night time. The Lunar Panel requires Lunar Reactive Dust which is created from Lapis Lazuli in the Resonator. Like the Solar Panel, the Lunar Panel is affected by rain.
Lava Mills generate 2 GP from an adjacent block of Lava. The Lava Mill only benefits from one adjacent Lava block. Placing Lava against other faces will not increase the output.
Wind Mills generate approximately 1-2 GP from the wind. This value fluctuates constantly and receives a boost from rain and storms. Testing suggests that placement at higher altitudes increases the Wind Mill's output.
Fire Mills generate a steady 2 GP from being placed over Fire such as that from a burning piece of Netherrack.
Top Tier
Water Mills generate up to 16 GP from the flow of adjacent water. Crafting requires Stoneburnt which is created in the Resonator
By placing water source blocks in the spots indicated by sand, multiple Water Mills can be arranged to work at maximum output in a small amount of space. The illustrated pattern can be tessellated to minimize the space required while still providing maximum output.
God Tier
The Dragon Egg Mill is the ultimate GP generator. When a Dragon Egg is placed on the Dragon Egg Mill, it will siphon Ender energies and produce a whopping 500 GP. Just don't bump it.
