Energy security at risk after forced plant output cuts 12:33 | 11/05/2021 Energy security at risk after forced plant output cuts Put into operation in late 2019, Sinenergy Ninh Thuan 1 Solar Power Plant from Singaporeâs Sinenergy Holdings Pte., Ltd. has had to cut the capacity by 20 per cent over recent months, especially during the peak hours of 10am-2pm, due to the overloading of the power transmission lines and transformer stations. Plant manager To Van Viet told VIR that cutting power outputs has caused millions of US dollars in loss every year. Located over 60 hectares in the south-central province of Ninh Thuanâs Ninh Phuoc district and costing $57 million of investment, the 50MW solar power plant is estimated to gain around $7.4 million annually at full capacity. âCutting power generation capacity could delay return on investment, as well as push some investors into much more difficulties if borrowing money from banks,â Viet said.
