July 10, 2012 (LBO) – Sri Lanka’s hydro storage rose 30.4 GigaWatt hours to 319.1 GWh after strong showers on July 09 brought inflows mostly into small ponds in the Kelani River complex. According Sri Lanka’s state-run Ceylon Electricity Board data total hyrdo storage slipped to 288.7 GWh (millions of units) on Sunday, after slipping below the 300GWh mark earlier in the week, amid an exceptional dry spell and failed monsoon.
The CEB’s website said on Monday 29.6GWh hours of energy was generated of which 25.6 percent of 7.6GWh were hydro. A strong shower causes most small ponds in the Laxapana hydro power complex to spill.
A strong shower can usually bring inflows in to the reservoirs for two or three days as water held in the upper catchment seeps down. Sri Lanka’s hydro catchment areas are under threat from human encroachment.
Peak power demand was 1,822MW on Monday down from 1900MW plus level seen in recent weeks amid somewhat cooler weather.
CEB’s published data totals centrally dispatched plants and the contribution of mini-hydro power is effectively shown as a negative number from the total.
