Power supply units
Custom module to autofill six parameters for use in Template:Infobox power station
Parameters are:
ps_units_operational
	→ The number of generation units operational and their nameplate capacity
	→ Example: 3 × 100 MW<br>1 × 110 MW
ps_units_manu_model
	→ The manufacturer and model of the generation units
	→ Example: Vestas V164
ps_units_uc
	→ The number of generation units under construction
	→ Example: 2 × 150 MW<br>1 × 160 MW
ps_units_decommissioned
	→ The number of generation units decommissioned
	→ Example: 1 × 75 MW<br>1 × 70 MW
ps_units_planned
