1.Private generation: industrial co-generation, capacity generation.
2.Interconnected System: Capacity savings, power sharing amongst units for economic allocation
1.
Private generation: Any electrical power generated apart from the power generated by
publicly owned power companies (at least here in the USA).
Industrial co-generation: For example, power generated from the excess (or waste) heat of an industrial process that is then used to heat water to steam which is then used to power a electricity generating turbine.
Capacity generation:
Total (or maximum) electrical power generation by generation type (
private, in this case, if I'm following your question sequence correctly), generally subdivided by energy source.
2.
Interconnected Systems:
Capacity Savings. I'm not sure in what
context this concept was discussed. Inter-connectivity amongst various power generating entities serves two purposes:
A.
Back-up power availability during times of excess demand across (or between) usage areas and,
B.
A reduction in the need for additional capacity within a single usage area. This results in a reduction in the costs of generation developmental costs within a particular usage area.
Lastly, "power sharing amongst units for economic allocation" sounds like governmental gobbledygook...
