To ensure grid safety and reliability, sizing of the generation (in kW) will be limited to two times customer load up to 10 kW AC maximum.
Generation over 10 kW shall be subject to special review to ensure grid safety. Cost of studies and upgrades associated with generation over 10 kW will be established during the permitting process and paid prior to connection.
