Many companies with high power demands (in the megawatts range) are currently connected to the medium-voltage grid (for example at 13 kV).
Migrating to a higher voltage level (138 kV might be one possibility) can be a very attractive option for two main reasons:
1) Lower grid usage tariffs (wire fees)
and
2) Fewer unplanned power interruptions (in terms of hours per year)
The feasibility of this switch, of course, depends on the specific circumstances of each case. If you would like to explore this topic further, feel free to reach out!
