Nepal's Investment Board approves Rs 21 billion for two semi-reservoir plants

The 58.9 MW Nar Khola and 46.72 MW Sani Bheri-3 projects got investment approval at the board's 68th meeting, chaired by the prime minister.

For you: Most Nepali plants are pure run-of-river and fall sharply in winter. Peaking and storage designs are the engineering answer, and they need civil engineers for dams, intakes, desanders and pondage, plus electrical engineers for generation scheduling and grid connection. Projects of this size, at around Rs 10 billion each, are the kind of mid-scale work where fresh graduates often get site and design jobs. The AI-infrastructure line is also worth watching for computer engineering students interested in data-centre power.

Arun-3 in Nepal gets a February 2028 target for commercial power

The Investment Board set a new commercial-operation goal for the 900 MW Arun-3 and ordered Upper Karnali construction to be facilitated at once.

For you: Arun-3 is a 900 MW project with long headrace tunnels and a large underground powerhouse. A firm date tells contractors and consultants how long site jobs in tunnelling, quality control and commissioning are likely to last. For BEI and electrical-minded students, the export link and grid integration of 900 MW is the kind of system-level problem that appears in power-system and protection courses.

Nepal's Tanahu storage hydropower project reaches 78 percent progress

The 140 MW Seti River reservoir project has poured over 507,000 cubic metres into its 140 m dam and nearly finished its headrace lining.

For you: Tanahu is a storage-type plant, unlike most of Nepal's run-of-river schemes, and storage is what keeps power available in winter. The project is a working example of mass-concrete dam construction, river diversion, tunnel lining and grid connection in one place. Monthly concrete volumes show how construction planning is measured. Graduates often enter such projects as site engineers for contractors or consultants, and similar reservoir schemes are planned elsewhere.

Nepal's NEA rules out winter load-shedding, plans 1,154 MW of imports

With the Trishuli 3B hub substation lost, the NEA is leaning on Kulekhani and Indian imports to get through the dry season without power cuts.

For you: This is a live example of the gap between installed capacity and firm capacity that power-system courses teach. Run-of-river plants lose most of their output when rivers drop, so a single substation failure and a dry season can turn an exporter back into an importer. Students in BEI and electrical subjects can follow how load forecasting, reservoir scheduling and cross-border transmission limits decide whether the lights stay on. Civil students can note why the one reservoir scheme, Kulekhani, carries so much of the winter load.

Nepal's NEA studies a bypass line to free 176 MW stranded by a lost substation

NEA Engineering Company has two months to design a direct Chilime-Matatirtha line around the destroyed Trishuli-3B hub.

For you: This is power-system engineering students can map onto their syllabus: substation topology, single points of failure, line routing, tower foundations and voltage choice for a double-circuit line. The fix being a bypass rather than a rebuild shows how network redundancy is valued only after it is missing. NEA Engineering Company is a Nepali design firm, so the work also shows that grid design jobs exist at home, not only abroad.

Rebuilding Nepal's flood-hit power system put at Rs 390 billion

A government needs assessment prices recovery of plants, substations and lines on the Bhotekoshi-Trishuli corridor at about Rs 390.6 billion.

For you: Rs 390 billion of rebuilding will run for years and will need hydraulic, structural, geotechnical and electrical engineers, from damage surveys to redesign and commissioning. It also shows how one corridor can carry a large share of a country's generation, a point power-system planners call concentration risk. Civil and BEI students can expect reconstruction, protection and substation design to be a steady source of consulting and contractor jobs in the next few years.

Experts say Nepal's Trishuli hydropower rebuilds need new design rules

Engineers argue old flood estimates failed, and call for glacier studies, remote-controlled powerhouses and safer tunnels before rebuilding.

For you: Design floods, return periods and site selection are taught in hydrology and hydropower engineering, and this debate shows those numbers being questioned in practice. If new rules require catchment-wide hazard studies, glacier lake mapping and remote-control systems, they create demand for engineers who can combine hydrology, GIS, geotechnics and automation. For BEI students, remote powerhouse control and early warning are instrumentation and communication problems. None of these proposals has become a formal standard yet.

Nepal's NEA plans ten transmission lines, two of them 400 kV, this year

Hetauda-Dhalkebar and New Butwal-Gorakhpur lead a list of ten lines Nepal aims to energise in FY 2026/27, most of them 132 kV.

For you: Nepal's generation has grown faster than its ability to move power, and transmission is now the bottleneck for both exports and winter imports. Line projects involve tower foundations on hills, conductor selection, protection schemes and substation design, which link civil and electrical courses. For students, NEA's transmission directorate and its contractors are steady employers. The 400 kV lines also show why voltage level matters for losses over long distances.
