Distributed Generation Capacity Limits & Definition Proposal
The content discusses distributed generation capacity limits in various countries like Uganda, Kenya, Ghana, and more. It also explores factors impacting the definition of distributed generation systems and proposes a detailed outline for defining distributed generators connected to distribution networks.

Distributed Generation Definition and Generation capacity limits
Uganda: Systems <0.5 MW Kenya: Systems <1 MW; <maximum load demand in kW over the past 12 months Ghana: onsite generation; systems <0.5 MW; Mozambique: No capacity limits; generation to match annual consumption Namibia: onsite generation; systems <0.5 MW; Madagascar: <0.5 MW; excess generation capped at 60% of annual consumption ESWATINI Eswatini: systems <1 MW; LESOTHO South Africa: Onsite generation systems <1 MW Lesotho: no definitions yet
COUNTRY DG CAPACITY 1kWp- 1MWp DG capacity limited to consumer supply capacity Generation should not exceed consumer annual energy consumption Pakistan Varies on subnational level: less than 500KWp or 1MWp or 2MWp or no cap India No cap on installed capacity National total annual quota in place Indonesia Residential: 1- phase: 12kWp, 3- phase: 72 kWp Commercial: up to 1 MWp or 75% of their maximum demand (whichever is lesser) Industrial: 60% of the fuse rating Malaysia No capacity limit National total capacity cap cannot be exceeded (2,600 MW) Vietnam 15/03/2025 3
Factors in DG definition Any generator connected to the Distribution Network Additional factors to be considered: Behind the customer meter? limited to customer supply capacity Self-consumption vs pure generator/IPP (for export only)? Total generation limit compared with customer annual consumption? Export limits? Nationally set size constraints

Definition proposal Connected to Distribution network Behind the meter ( on site ) Self-consumption vs pure generator Nationally set maximum "Distributed Generator" means a facility that generates electricity, often from renewable energy sources, such as solar PV, wind, biomass and hydro, with or without storage systems, which is connected to and synchronized with the Distribution grid, and with a generation capacity of up to (500kW? 1000kW?). These facilities are located on residential, commercial, rural, public or industrial consumer sites, generate power mainly for self- consumption, and may or may not inject surplus electricity into the distribution electricity network.
