Could a battery energy storage system boost solar power generation in Vietnam?

Image: Sunseap Solar PV power generation in Vietnam could about to be maximised through the integration of battery energy storage systems (BESS), with consultancy AqualisBraemar LOC Group (ABL Group) hired to conduct feasibility studies across multiple PV plants following curtailment issues in the country.

What is the current state of Bess in Vietnam?

The Current State of BESS in Vietnam As of 2024, Vietnam has practically no BESS installed. So far, only private renewable power projects have trialed BESS development, there is nothing at the utility scale. The largest electricity storage project in Vietnam is the Bac Ai Pumped Storage Hydropower Project.

How much does a Bess system cost in Vietnam?

In 2023, EVN PECC3 estimated that the cost for a 2 MWh BESS system was 360–420 USD/kWh, and that the investment would requires electricity prices in Vietnam above 18 UScent/kWh to be profitable – this is twice the current levels. However, BESS costs are declining rapidly.

What is the solar PV market in Vietnam?

The present solar PV market in Vietnam is projected to be approximately 5 MWp, with 80% of off-grid applications in rural regions. since larger ground-mounted PV systems are being developed and Solar energy has yet to be incorporated into national energy development initiatives such as the National Power Development Plan (Energypedia, 2019).

Why are solar projects in Vietnam suffering from curtailment issues?

How much does a household Bess installation cost?

Household BESS installations are typically in the range of 3-20 kWh. As an example, in the USA a 13.5 kWh Tesla Powerwall costs $11 500 with installation. These systems enhance self-consumption by storing surplus solar energy generated during the day for use at night or during cloudy periods.
