This initial environmental examination (IEE) including an environmental management plan (EMP) for the proposed Electricity Grid Modernization Project (EGMP or the Project) by Nepal Electricity Authority (NEA) has been prepared in compliance with the Asian Development Bank’s (ADB) Safeguard Policy Statement (2009) and national (Nepal) environmental assessment health, and safety requirements. 2. The project will finance high-priority transmission and distribution systems investments under three outputs. Output 1: electricity transmission capacity in project areas strengthened and modernized; Output 2: electricity distribution system in project areas modernized; and Output 3: capacity of NEA and electricity users in project areas strengthened. Only the first two outputs involve physical activities. Output 1 will involve the construction of construction of 88 km of 132 kV and 25 km of 220 kV new transmission lines. It also involves the upgrade of 185 km of existing 132 kV and 66 kV transmission lines and automation of 34 existing substations. Output 2 will involve the construction of 30km of 33 kV distribution lines and a distribution command and control center. It also involves the installation of an estimated 350,000 smart meters. Between Outputs 1 and 2, 8 new or extended transmission/distribution substations will be constructed. The project is aligned with the following impacts: Reliable and efficient electricity for all achieved by 2028 and NEA developed as modern and sustainable corporate entity providing reliable services to its customers. The project will have the following outcome: coverage, reliability, efficiency, and financial sustainability of electricity supply in Nepal improved. 3. The project is estimated to cost $195 million. ADB will finance the project through a $156 million project loan while the balance of funds will come from counterpart funding by the Government of Nepal. NEA will serve as the executing agency and will implement the EGMP through its Project Management Directorate (PMD). The EGMP will be implemented over 5 years and is expected to be completed by March 2026. 4. Under ADB’s Safeguard Policy Statement (2009), the EGMP has been classified as “B” for environment requiring the preparation of an IEE. Following the requirements of ADB’s Safeguard Policy Statement (2009) and national (Nepal) environmental assessment health, and safety requirements, this IEE has been prepared, covering all components of the EGMP having environmental impact. 5. The transmission line and substation work under Output 1 will be spread across various locations in Province number 1, Bagmati province, Gandaki province, province number 5, and Karnali province. 6. A total of 227.5 ha will fall under the rights of way of the 3 new overhead transmission lines, including 86.7 ha of forest land for which a compensatory reforestation program will be implemented. Compensatory reforestation at a ratio of 1:25 will be provided for the 12,950 trees to be felled on forest land (8,358 private trees will also be lost) as well as forest land replacement for 3 ha of land to be planted at 1,600 trees/ha under tower footings. In particular, 7.4 km of the new Ghorahi-Madichaur transmission line runs ii along a river valley that falls within the IUCN category VI Chure Conservation Area which is designated to conserve natural habitats whilst allowing sustainable use of natural resources. 400 m of this section also passes through the outskirts of the Dang Deukhuri Foothill Forests and West Rapti Wetlands Important Bird Area. Due to the location of Ghorahi substation within the protected area, whilst alternative routings were considered to minimize forest loss, it has been unavoidable to pass through it. However, its protected area management plan specifically includes improving access to energy including through “extension of access to national electricity power transmission” as an objective. 13.32 ha of land within the Chure Conservation Area will fall under the right of way of the transmission line which is mainly agricultural land (modified habitat) with existing road access; thus no forest land is impacted with the protected area and the transmission line will not open up access to it. Dang Deukhuri Foothill Forests and West Rapti Wetlands Important Bird Area was recently extended to include the Charinge Community Forest, this forest land supports a breeding site for critically endangered vultures, located approximately 2 km distant. To ensure ADB’s Safeguard Policy Statement (2009) critical habitat requirements can be met, and there will be no reduction in their population due to electrocution or collision, “bird sensitive” design following international good practice will be adopted including installation of bird divertors along the entire transmission line to minimize collision risk. During detailed design towers will also be located as far west as is possible from Charinge Community Forest and the river. Whilst the other new transmission lines do not affect protected areas,
