EVN claims hydro dams not to blame

HA NOI (VNS)  — Electricity of Viet Nam (EVN) claims that operation of hydro-power reservoirs in central region met operational guidelines and did not cause flooding in lowland areas.

EVN gave their assurances to a working session on Monday with the Ministry of Industry and Trade, hydro-power investors and the eight central localities where a large number of hydro-power plants are located.

The meeting was held in response to public concern that recent floods in central and Central Highlands region, which killed 41 people, were partly resulted from hydro reservoirs' irresponsible release of water.

Vice Chairman of Quang Ngai province's People's Committee Pham Truong Tho, agreed with EVN that hydro-power reservoirs in the province had not released flood waters or caused man-made floods in the central region after recent storms and deluges.

"During heavy rains, water in all reservoirs in the province flows freely and no reservoirs release water to cause more floods for the region," he said.

"The rains are so heavy, making the water rise quickly and suddenly in a short period of time," he added.

Vice Chairman of Quang Nam Province's People's Committee Nguyen Ngoc Quang also said the local authorities kept a close watch over the operations of four hydro-power reservoirs in the province.

In any case, he added, when these reservoirs release water the amount released always smaller than the amount of water flowing into the reservoirs.

Giving an example, Quang illustrated that during the peak period when water flowing into the Dak Mi 4 reservoir reached 4,360cu.m per second, the water released from the reservoir was only 3,900cu.m per second.

The director of the National Hydro-meteorological Forecast Centre, Bui Minh Tang, said continuous heavy rains created a huge volume of water flowing into reservoirs.

"The recent storms caused unexpectedly heavy rains on a large scale with a rainfall of 200-1,000mm in the region," he said.

Tang also stressed that all reservoirs were allowed to release water prior to any storm to enable them to store rainwater brought in by storms and to prevent flooding.

"It meant that reservoirs contributed to reducing floods, not causing them," he said.

Minister of Trade and Industry Vu Huy Hoang said although localities confirmed that hydro-power reservoirs basically operated in line with regulations, it was still essential to review the operational processes at all reservoirs, particularly hydro-power reservoirs to ensure they all met regulations.

At present, 268 hydro-power projects are under operation nationwide while 205 others are under construction. — VNS
