📈 The 70% Target: Where Cambodia Stands Today
A Market Already Far Ahead of Regional Peers
Cambodia’s clean energy share already exceeds ASEAN’s regional target of 35% by a wide margin. Clean sources – primarily hydropower, solar, and biomass – now supply over 63% of the country’s total energy consumption. By the end of 2026, that share is expected to reach approximately 67%， driven by newly approved wind, solar, and storage projects that are already under development.
The Power Development Master Plan 2022–2040
The roadmap to 70% is anchored in the Power Development Master Plan 2022–2040, which has already led to the approval of multiple renewable energy projects. The Master Plan halted new coal investments after 2024 and sets concrete capacity targets: 1,000 MW of solar by 2030 (rising to 3,155 MW by 2040), 900 MW of wind, 3,000 MW of hydropower, and substantial battery storage capacity. It is the central reference document for any major energy project.
While the current share of clean energy is high, a single‑source reliance on hydropower (which alone provides close to 45% of total installed capacity) creates seasonal vulnerability. Dry‑season power shortages remain an ongoing risk, underscoring the urgency of diversifying into solar, wind, and storage.
🏗️ The Project Pipeline: What’s Under Construction and Approved
💨 Wind Power: A New Frontier
Mondulkiri Wind Farm (150 MW) – Progress Update
The 150 MW wind farm in Mondulkiri province – Cambodia’s first large‑scale wind project – was approved by the Council for the Development of Cambodia (CDC) in January 2026 and is valued at approximately US$200 million. As of April 30, 2026, the project’s overall construction was 20% complete; one company has already moved into the actual construction phase. The facility will include 20–30 turbines per developer and is expected to create 42 local jobs while strengthening national grid capacity.
The project is part of a much larger 900 MW wind power pipeline in Mondulkiri. Cambodia’s National Assembly and Senate approved six wind projects in the province in 2025, positioning it as a hub for wind energy thanks to favourable mountain conditions.
Chinese EPC Involvement
China Energy Engineering Corporation (CEEC) is playing an active role in Cambodia’s wind sector. In January 2026, CEEC’s subsidiary China Gezhouba Group won a bid for one of Cambodia’s first‑batch large‑scale wind power projects, which includes 20 units of 8 MW turbines. Chinese EPC contractors are becoming key implementation partners for Cambodia’s renewable infrastructure.
☀️ Solar Power: A Major Updraft
350 MW Solar Project Approved
In April 2026, the CDC approved a 350 MW solar power station as part of a broader investment package totalling US$490 million across eight projects. Other included projects cover manufacturing, agriculture, and industrial sectors. The solar station will be one of the largest single solar installations in Cambodia to date.
30 MW RoofTop Quota (2026)
The Ministry of Mines and Energy has maintained the annual rooftop solar quota at 30 MW for 2026 – the same level as in 2025 – allocated by the Electricity Authority of Cambodia (EAC). This quota targets commercial and industrial consumers, and approved capacity is not affected by future quota cycles, providing long‑term certainty for C&I solar investors.
Green Bond Financing
A US$50 million green bond has been issued to finance a 60 MW solar PV plant integrated with a battery energy storage system– the first utility‑scale solar plant in Cambodia to combine PV generation with storage at the plant level. This hybrid model is being closely watched as a template for future solar‑storage integration.
🔋 Battery Energy Storage Systems (BESS) – Backbone of Grid Stability
● 1,000 MWh Battery Storage System (Operational)
In March 2026, renewable energy developer SchneiTec launched a 1,000 MWh BESS attached to its solar farm in Pursat province. It is the first and largest utility‑scale battery storage system in Cambodia, designed to improve grid reliability and reduce outage risks for households and industries. The system also serves as a crucial enabling technology for storing surplus solar and wind energy generated during the day for use at night.
● ADB‑Proposed 250 MW / 500 MWh BESS
A larger 250 MW / 500 MWh battery storage system has been proposed by the Asian Development Bank (ADB). The system will strengthen power system resilience, enable higher renewable integration into the transmission network, and serve as a critical electricity import interface with southern Vietnam, enhancing cross‑border power trade. This project is currently in the proposed stage, with several international financing sources involved, including the UK‑ASEAN Catalytic Green Finance Facility, the Green Climate Fund, and the World Bank.
💧 Pumped‑Storage Hydropower – The Anchor Battery
Upper Tatay Pumped‑Storage Project (1,000 MW)
In April 2026, Cambodia broke ground on its first pumped‑storage hydropower plant in Koh Kong province. The US$1 billion, 1,000 MW facility is one of the largest renewable energy installations in Southeast Asia. Engineered to act as a massive “battery,” it will store excess electricity and release it during peak demand to ensure a consistent energy supply. The project is a flagship of Cambodia‑China production capacity cooperation and the Belt and Road Initiative, with construction expected to be completed by 2029.
Pumped‑storage hydropower is the critical missing piece in Cambodia’s renewable strategy. Without it, the grid’s ability to absorb intermittent solar and wind power would be severely limited. The Upper Tatay BOT (Build‑Operate‑Transfer) project therefore unlocks the viability of a far larger renewable pipeline.
