Yuhuu~
Today, I have reviewed about TNB Distribution 33kV planning cycle and I put my focus on load forecast. The load forecast is used as a means of predicting future electricity demands or sales growth based on historical data.
The future electricity demand information derived will assist system planners in proposing new equipment and facilities as well as reinforcing and upgrading the existing system to meet the increasing demand.
Accurate, reliable, and defendable forecast will help planners in making prudent investment decision for system expansion, reinforcement and new plant-up.
The forecast horizon has been defined in accordance to the upcoming Malaysian Distribution code:
Short term 1-2 years
Medium term 3-5 years
Long term 6-10 years
Short term forecast is useful for operational planning and capital budgeting as well as for material procurement planning requirements.
PPU plant-up proposal and distribution network planning will use short-to-medium term forecast.
Alternatively, sub-transmission capacity planning or PMU planning will utilizes medium-term forecast.
A long term forecast are strategic in nature and being used to provide inputs and lead time for generation plants ups, substation sites and the associated way leave identification and acquisition.
