Cheap, clean and low cost renewable energy (RE) for the third consecutive day to Thursday (12) provided more than 50 per cent of Sri Lanka’s total electricity needs for the first time this year, Ceylon Electricity Board (CEB) data released on Friday (13) showed.
Thursday’s (12) RE figure was 63.62 per cent (23.19 gWh) and second was the environmentally damaging and expensive imported coal at 35.75 per cent (13.03 gWh) respectively.
Total number of electricity units consumed on Thursday was 36.45 gWh.
In like developments, Thursday’s RE electricity, similar to the immediately previous days, Wednesday (11) and Tuesday (10), was powered by the inter-monsoonal rains and was once more led by CEB Hydro which provided 70.50 per cent (16.3 gWh) of Sri Lanka’s total RE electricity needs on that day. CEB hydro in turn was led by the “Mahaweli” comprising the Victoria, Kotmale, Randenigala, Rantanbe and the Upper Kotmale reservoirs, respectively. RE’s total electricity contribution on Tuesday and Wednesday were 54.48 and 64.84 per cent, respectively.
Victoria, Kotmale, Randenigala and Rantanbe were built during President J.R. Jayewardene’s tenure (1977-1988) after obtaining grant and/or concessional aid from the UK, Sweden and the then West Germany, while Upper Kotmale, though conceptualized during the Jayewardene era was implemented during the Mahinda Rajapaksa era (2005-8 January 2015) after obtaining concessional aid from Japan.
The last time RE provided more than 50 per cent of Sri Lanka’s total electricity needs for three consecutive days was five months ago, on the 17, 18 and 19 December 2021 (51.67, 50.06 and 53.31 per cent) respectively.
