Vietnam : Transmission Grid- Downstream Evacuation Challenges

Vietnam (the leading country in SEA's Solar PV market)- it's cumulative solar PV installation will hit 5.5 GW end of 2019, making up 44% of South-East Asia’s total capacity. However, renewable energy projects in Ninh Thuận now face overloaded electricity grid - Within 1 year, the province installed more than 1,000 MW of wind power and solar power, but the transmission infrastructure has not kept pace with the development of electricity production. (10/18 projects in the province were forced to reduce capacity) The Catalyst behind this growth ?- EVN has agreed to continue the current feed-in tariff (FiT) rate of 9.35 US cents per kWh for rooftop solar-power projects nationwide until 2021 (earlier effective from June 1, 2017 to June 30 2019) to all types of solar technologies, including floating, ground-mounted, and rooftop solar-power projects (Solar PV’s growth from 0.3% to 8.3% of the total installed capacity of Vietnam in less than a year) What can be done?

Was this a problem that was seen ahead of time, or did it catch those in the industry in Vietnam off guard?

CTC Global is seeing a number of reconductor projects in Vietnam where power companies are using ACCC Conductor to increase the capoacity of existing transmission lines without the need to replace existing structures.
