Attractive market opportunities for distributed generation may exist that require network interconnection.
Secondary networks are used in about 90% of the cities in the US having a population of >100,000 and in more than 1/3 of the cities with populations between 25,000 – 100,000.1
Some of the more attractive and most accessible market opportunities for DG involve commercial customers in urban areas:
Relatively high electricity prices
Reasonable gas prices, accessibility to gas
Electricity can be a significant operating cost
Customers care about costs, reliability, power quality and green attributes
Right size (I.e. MW) for some DG technologies (microturbines, fuel cells and recip engines)
It would appear that many of these customers are in urban areas on grid or spot networks.
