ECONOMYNEXT – Sri Lanka’s Ceylon Electrical energy Board stopped curbing photo voltaic power for grid stability April 20, with robust demand resuming as holidays ended, a utility spokesman mentioned.
The CEB had earlier curtailed about 500 rooftop operators who had been supplying power on a business foundation and requested about 100,000 different customers to close down their system through the New 12 months holidays to take care of grid stability until April 21. Nevertheless the curtailment had stopped on April 20.
“As of now there isn’t a renewable curtailment in impact,” CEB spokesman Dhammike Wimalaratne mentioned in an audio assertion on April 21.
“On behalf of the Ceylon Electrical energy Board, and our 7 million electrical energy shoppers, we lengthen our heartfelt appreciation to your well timed assist, which allowed us to take care of a protected, steady and un-interrupted energy provide, for the complete nation.”
The CEB additionally shut down non-public thermal vegetation, certainly one of its coal vegetation and thermal gas vegetation within the daytime through the vacation.
An electrical energy grid has to close down vegetation to match demand and begin up new ones when demand goes up throughout weekday.
The contracts for personal energy have a capability cost which works for capital funding and an power cost for gas value which can be charged when energy is equipped.
Within the case of small renewable energy initiatives the place provide is unpredictable there was just one all inclusive cost with the utility dedicated to purchase all their energy output.
This was the follow up to now everywhere in the world when photo voltaic and wind made up solely a small proportion of the full provide. Nevertheless, when their share went up, photo voltaic (and wind to some extent) tended to overwhelm the grids as they may not be curtailed to regulate to the grid.
Utilities often use hydro energy vegetation to take care of frequency however there’s a restrict that they will soak up.
Utilities are actually developing with new methods together with requirement to have batteries for ramping or for storage over a number of hours, encouraging self-consumption and limiting the power that may be exported to the grid. (Colombo/Apr22/2025)
