Planning Code for Intra-state Transmission- Planning Philosophy
1. STU would formulate perspective plan for intra-State transmission system. These perspective transmission plans would be continuously updated to take care of the revisions in load projections and generation scenarios, considering the seasonal and the time of the day variations.
2.The STU shall carry out planning process from time to time as per the requirement for identification of intra-State transmission system including transmission system associated with Generation Projects, strengthening of intra-State transmission system to absorb / evacuate power from the ISTS.
3. STU shall plan, from time to time, system strengthening schemes need of which may arise to overcome the constraints in power transfer and to improve the overall performance of the grid
4. All Users, CTU, In-SGS and Karnataka Renewable Energy Development Limited (KREDL) and Users shall supply to the STU the desired planning data from time to time to enable them to formulate and finalize its plan
5. Special attention shall be accorded, by STU and Users for adequate compensation for active and reactive power management considering various technological options
6. In case Long Term Access Applications require any strengthening in the intraState transmission system to absorb/evacuate power within the State, the applicant shall coordinate with the STU
7. STU shall have to plan their systems to further evacuate power from ISTS and to optimize the use of the integrated Transmission network
8. the associated intra-State transmission system shall also be discussed and reviewed before implementation during the discussion for finalizing the ISTS proposal

Planning Code for Intra-state Transmission- Criterion
1. The long term applicants seeking transmission service are required to pose their end-to-end requirements well in advance to the STU so as to make-available the requisite transmission capacity
2. The transmission customers are also required to provide a basis for their transmission requirement such as – size and completion schedule of their generation facilityand their commitment to bear transmission service charges
3. Planning of transmission system for evacuation of power from hydro projects shall be done river basin wise
4. In case of highly constrained areas like congested urban / semi-urban area, very difficult terrain etc., the transmission corridor may be planned by taking long term perspective of optimizing the right-of-way and cost.
5. STU shall act as the nodal agency for In-STS planning in coordination with distribution licensees and intra-State generators connected/to be connected in the State grid
6. The various intra-State entities shall be supplied power through the intra-State network only
7. Critical loads such as - railways, metro rail, airports, refineries, underground mines, steel plants, smelter plants, hospitals etc., shall plan their interconnection with the grid, with 100% redundancy and as far as possible from two different sources of supply.
8. Appropriate communication system for the new sub-stations and generating stations may be planned by the STU and implemented by licensees as well as generation developers
[clause 4.6.3]
