4. About Grid Codes  Almost all SAPP member countries have own grid codes  Jurisdiction of Regulators  Interconnection requires harmonisation of some codes, as was done in EAPP  SAPP Operating Guidelines  Inferior to grid codes, revised in 2014  Has penalties for non-compliance  Includes requirements for connection of IPPs 13 13 SOUTHERN AFRICAN POWER POOL SOUTHERN AFRICAN POWER POOL
