Renewable energy business forecast on Cambodia

Renewable energy in Cambodia

Cambodia, which relies heavily on hydropower, has witnessed power shortages due to reduced hydropower generation owing to draughts and lower water levels in the dams.

The country’s recent 10-year plan has low impetus on developing mainstream dams and seek alternative sources to meet the electricity demand from coal, LNG, solar PV and imports from neighbouring countries.

Around 83 percent of the new generation capacity built between 2020 to 2030 will be from coal (56 percent) and solar PV (27 percent) while hydropower (8 percent) and Oil (9 percent) are likely to account for the remaining new capacity, says GlobalData, a data and analytics company.

Cambodia had looked at hydropower for meeting its power needs. Hydropower accounted for 58 percent (nearly) of the generation in 2018, falling by 45 percent (approximately) of the generation in 2019.

“The droughts in 2019 had brought down the share of hydropower in the nation’s generation mix significantly, compelling to opt for alternative sources to support the generation mix and avoid such unforeseen circumstances,”Ankit Mathur, practice head for Power at GlobalData, said.

The Mekong river provides a strong potential for the development of hydropower in the country. However, the development has found strong opposition from the environmentalists for a potential harm to the fisheries and farmlands next to the basin.

The government is keen to invest in the expansion and upgradation of the electricity infrastructure. It is estimated that the current transmission and distribution network is likely to expand at a compound annual growth rate (CAGR) of 11.8 percent until 2025, almost doubling the transmission line length from the present.

Cambodia’s recent approval of more than US$830m worth electricity infrastructure projects, including a 150MW hydro project, 265MW coal-fired plant and three transmission lines, clearly draws the line for lower hydropower development and focus on alternative sources.

Cambodia looks to build a sustainable generation mix that will support the expansion of the national grid and trim the electricity prices with lower imports. The increased expansions of the coal-based power plants and LNG suggest that the country is significantly reliant on imported fuel and electricity.
