Connecting a data center to a public grid is no longer as straightforward as it used to be. For small facilities with a load of several megawatts, it is generally not a problem. However, for a large center requiring continuous supply of several hundred megawatts, it may become an issue.
In general, connecting such a big consumer at a single location normally requires certain development of the grid infrastructure. And this is a process that takes time, sometimes several years. Although this is typically not an issue for heavy industry, where new major investments are planned many years in advance, it can effectively prevent a project from being constructed in the fast-moving world of IT.
Therefore, the traditional grid-and diesel solution, while still technically valid, becomes unsustainable for large, modern data centers, both environmentally and economically. Fortunately, recent progress in power generation technology offers an alternative solution.
