5. Title,  number of pages and language(s) of the notified document: Mini-Grid 
Systems – Part 9: Interconnection of less than 1MW of Generation with the National Grid 
(9 page(s), in English)   
6. Description of content: This standard provides a framework within whic h consumers and 
mini-grid developers know what the minimum requirements are for service quality 
including service voltage  level ranges at the consumer premises, maximum harmonic 
levels in the wave shape, and continuity of service as specified in IEC Standa rds EWURA 
Distribution and Grid Codes.  
This standard provides minimum interconnection requirements for mini -grid generation 
and associated distribution network with national utility (TANESCO) and specifies  
performance, operation, testing, protection, metering and testing procedures. The 
requirements shall be met at the point of common coupling (PCC). The equipment,  
hardware and software shall meet the specified requirements and standards and shall be 
technically qualified to operate under the local ser vice conditions . 
7. Objective and rationale, including the nature of urgent problems where
