Power grid

A power grid is a piece of equipment that can house a charged power component, which is a type of large battery that can provide power for a limited time until it runs out of energy. A power grid always houses several to hundreds of power components, such as persistent energy batteries (PEBs) and racetrack batteries (RTBs).

Power grids run on charged power components such as PEBs and RTBs that are charged using a variety of energy sources - wind mills, sun panels, hydroelectric power and nuclear fission. These charged PEBs and RTBs  are called APEBs and ARTBs (sometimes referred to as Artby's). These APEBs and ARTBs are then transported - often by airship or spaceship - to the location where they are used in a power grid. This power grid then locally powers a community. When a PEB or RTB runs out of power they are replaced by a charged one. The "empty" PEB/RTB is then transported back to the energy farm and again charged for new use.

On Folkvangr, the Folkvangr Council concerns itself with supplying and retrieving PEBs and RTBs from communities - effectively being in charge of the energy sector on Folkvangr. This energy sector is communally paid for and administered by an alliance of all communities themselves - the Public Utilities Department (PUD) which also collectively maintains other public utilities, such as transport, hospitals and clean water supply.
