After that date, tenants (excluding transients) of mobile home parks must be individually metered and billed by the electric utility.02.Exception for Sub-Metered Parks. Any mobile home park connected for service on or before July 1, 1980 whose spaces for non-transient tenants are been fully sub-metered for electricity by the park owners need not be individually metered by the electric utility supplying the park. A mobile home park sub-metered by the park operator must charge each of their tenants the same rate for electric service that a residential customer of the utility serving the park would charge the tenant if the tenant were directly metered and billed by the utility. Upon request, the utility will provide written instruction on how to calculate bills for sub-metered tenants in conformance with the utility's applicable rate schedule.Idaho Admin.
