Electricity Customer Classifications
Large Commercial and Industrial (C&I) Customers
Large C&I customers are usually defined by their annual peak demand, which is different in different markets. In Texas, large C&I customers are those with greater than 50KW peak demand during the year; in Pennsylvania peak demand must be greater than 25KW. In many markets, large C&I customers are exempt from some of the market rules that apply to smaller customers and therefore receive customized and highly competitive pricing and contract offerings.
Small Commercial Customers
Small commercial customers are those with annual peak demand below the threshold defined for large C&I customers. Pricing and contract offerings from retailers for these customers are highly standardized and generally not negotiable.
Residential customers are those with electricity service to residences they own or lease. In many venues, residential service is broken down into two or more size categories based on usage level for the purpose of pricing because there is a wide disparity in usage due to residence size and design. Pricing offerings from retailers are usually required by PUCís to include all charges with the exception of meter fees and taxes. Contracts are usually standardized and non-negotiable.
