RE meets over 50% of demand


Cheap and clean renewable energy (RE) provided over 50 per cent of Sri Lanka’s (SL’s) daily electricity needs in 44 (57.14 per cent) out of the 77 days that transpired  to  Wednesday (24), Ceylon Electricity Board’s (CEB’s)  yesterday’s (25 ) data showed.

The last time, where for a period longer than this, where RE was the dominant player in Sri Lanka’s electricity sector for a consecutive number of days, took place nearly a year ago, where for 72 consecutive days, from 5 October 2021 to 15 December 2021, over 50 per cent of the island’s electricity needs were met by RE, once more led by ‘CEB Hydro’.

Meanwhile, in 32 (41.56 per cent) of the remaining 33 days to  Wednesday, over 50 per cent of the island’s daily electricity needs were met by the pollutive and imported fossil fuels (FFs) comprising coal and diesel and in the other single day (1.30 per cent), splits were evenly  (50:50) shared between FFs and RE, respectively

Consequently, RE led by ‘CEB Hydro’ provided over 50 per cent of Sri Lanka’s electricity demand for 25 consecutive days to  Wednesday (24 August), with   Wednesday’s “CEB Hydro” percentage figure alone being  equivalent to 87.20 per cent of total RE, CEB statistics further showed.

However in the 236 days that have transpired in the year to   Wednesday, RE was responsible for providing 50 per cent or over of Sri Lanka’s electricity needs in only 75 (31.78 per cent) days and FFs in the balance 161 (68.22 per cent)  days.

In related developments, of the total electricity supplied by the CEB to consumers in Sri Lanka on Wednesday which was  39.72 giga Watt hours (gWh), FFs share was 13.62 gWh (34.29 per cent)  and RE’s share was 26.1 gWh (65.71 per cent) respectively.

Wednesday’s FFs breakdown comprised CEB Coal 6.48 gWh, Private Sector (PS)/independent power producers’ Diesel 4.56 gWh and CEB Diesel 2.58 gWh respectively.  Wednesday’s RE breakdown comprised CEB Hydro 22.76 gWh, followed by PS Mini-Hydro 1.26 gWh, PS Wind 0.99 gWh, CEB Wind 0.6 gWh, PS Biomass 0.25 gWh and PS Solar 0.24 gWh respectively.
