It might be that they can't. (Well, not without spending even more money or time.)
They're looking for power which:
1. Fits on-site, rather than needing more space or being far away and dependent on the grid.
2. Can be ramped up on-demand, to keep their stuff running if there's a blackout.
3. Prioritizes their facility with "first dibs" when there are brownouts or other issues.
4. Can be built quickly so that they can finish the facility and start selling/renting.
These requirements are tend to conflict with the goals of making cheap power for sale: An offshore wind-farm might mollify local ratepayers, but it doesn't do anything for their facility reaching "ready".
