REVISED ELECTRICITY TARIFFS - Sri Lanka

REVISED ELECTRICITY TARIFFS & POSSIBLE NEXT STEPS TO REDUCE THE
We forward herewith the Electricity tariffs that became effective from 1st January 2011,
published by the Public Utilities Commission of Sri Lanka (Please see Attachment 1).
We are pleased to inform you that the current tariff increase is closer to the 8% level
announced in the Budget, much lower than the proposed tariffs that were announced by
the Public Utilities Commission for public consultation on 24 November 2010.
Kindly note that except for industries where contract demand is less than 42kVA (I‐1
category) all industries (I‐2 and I‐3) will be billed on Time of Use tariff scheme with lower
tariff during off peak time from 10.30pm to 5.30am. and high tariff during peak time from
6.30pm to 10.30pm. Hotels will be charged a separate rate, somewhat higher than the
industry rate. Here again all hotels with contract demand exceeding 42kVA (H‐2 & H‐3) will
be billed on time of use basis.
The off peak tariffs are much lower than the peak tariffs (please see attachment) and the
Electricity Bill can be reduced by shifting some of the electricity consuming operations from
peak to off peak time or day time, where it is possible. We share with you some points that
were expressed by an eminent Energy Expert at a seminar organized by the Ceylon Chamber
on Time of Use tariffs in October 2010, which might be useful for those enterprises that are
yet to take measures to shift their electricity use patterns.
What can bulk customers do to be ready for Mandatory TOU pricing from January 2011 ?
• Step 1: Have a load profile done for your electricity requirements
– Select a few typical working days, profile at least 48 hours
– Use recording equipment (can be done even manually, by reading meters at 0530,
1830 and 2230)
– May even be available in previous energy audit reports
• Step 2: Examine the peak‐time use, day‐time use
– Is peak‐time use more than 17% ? Then examine what causes it and examine how
to minimise such loads. Ex.
• reschedule water pumping, optimise chiller operations in the hotel (different
rates for day time and night‐time functions ???)
• reschedule ball mill operations in the cement factory,
• stop the washing plant at 1830 in the garment factory
• run the bambury mixer only in the night shift, in the rubber factory
– Examine how to further reduce demand both in peak and day period.
• Step 3: Implement load management and monitor
– Continue to monitor the energy use in the three intervals (before and after the TOU
– Can be automated, as well
