Power Transmission and Renewable Energy Integration

Overview of Power Transmission and Renewable Energy Integration

Bangladesh's power sector is expanding generation capacity while simultaneously upgrading transmission lines. As utility-scale solar and wind facilities are being dispersed across the country, integrating these sources into the existing grid in a stable way has become the central infrastructure challenge.

PGCB (Power Grid Company of Bangladesh) and SREDA (Sustainable and Renewable Energy Development Authority) are implementing a transmission-renewable integration roadmap and moving toward adding transmission capacity at scale to support a target of 40% renewable electricity by 2041.

Infrastructure gaps
Transmission shortfallGeneration exceeds transmission capacity
SubstationsInsufficient renewable interconnection points
MeteringLimited AMI/smart metering coverage
WorkforceShortage of grid operation engineers

Korean Company Participation Opportunities

01
Transmission lines and substations EPC
Korean firms can participate in EPC for more than 5,000km of transmission expansion and 50+ new substations. They can export 400kV and 765kV transmission equipment such as towers, conductors, GIS units, and transformers, while handling detailed substation engineering and execution. The core advantage is experience with heavy-duty transmission infrastructure and utility engineering.
02
ESS and smart grid
Large-scale GWh ESS systems and smart-grid solutions can stabilize renewable output. A package offer including batteries, PCS, EMS, and demand-response systems, for example Korea SDI and Korea Energy Solution, is well aligned with near-term procurement needs.
03
Renewables integration consulting
Korean specialists can support grid-integration consulting for high-share renewables, including system impact studies, protection-coordination design, LVRT settings, and reactive power compensation planning.
04
AMI and smart meter deployment
Export of nationwide AMI (advanced metering infrastructure) and smart meters is progressing as demand for metering modernization increases. Bangladesh can leverage Korea's large-scale rollout experience to accelerate distribution-level digitization and loss reduction.
