For years, Nepal's independent power producers have had exactly one customer that mattered: the Nepal Electricity Authority. On October 1, 2026, the Electricity Regulatory Commission published the legal instrument that finally breaks that exclusivity, the first amendment to its open-access directives, which lets private traders wheel electricity across NEA's national transmission grid for a regulated charge. The ERC open access wheeling charge for the current fiscal year was announced the same day: Rs 4.13 lakh per MW per month for medium and long-term access, and 57 paisa per kilowatt-hour for short-term trades. Here is the honest version: the directive is real and in force, the charge figures come from the chairman's public announcement rather than the document itself, and whether any private trader actually uses the open grid now depends entirely on whether that price makes trading worthwhile.
The document is the "विद्युत् प्रसारण तथा वितरण प्रणालीमा खुल्ला पहुँच सम्बन्धी (पहिलो संशोधन) निर्देशिका, २०८३" (Open Access (First Amendment) Directives, 2083), approved at the Commission's 320th meeting on 2083/06/02 and published on the Commission's official website on Ashwin 15, 2083 (October 1, 2026), where the full PDF is available for download. It amends clause 33 of the original Open Access Directives, 2082, the clause that governs how the transmission charge for open access is computed: a monthly rate for medium and long-term open access, and a separate rate for short-term open access. It also replaces the implementation timetable in Annex 3, which assigns the Commission itself the remaining rulemaking. The supporting framework is further along than the amendment alone suggests: the Commission's notice board shows the grievance-redressal mechanism for open-access customers, the balancing and settlement directives, the deviation settlement mechanism, and the metering directives all published between Shrawan and Ashwin 2083.
The numbers that will decide the economics came not from the directive's text but from its chairman's mouth. At the public event on October 1, held in the presence of Energy Minister Birajbhakta Shrestha, ERC Chairman Dr. Ram Prasad Dhital announced the determined charges for fiscal year 2083/84: Rs 4.13 lakh per MW per month for medium and long-term open access on the national transmission grid under NEA, and 57 paisa per kilowatt-hour for short-term open access, as reported by Hamro Artha and Arthikpati. Dhital said the computation used NEA's audited financial statements for FY 2081/82 and the Authority's estimated annual revenue requirement for FY 2082/83 and 2083/84, applying the methodology the amended directives prescribe. The distinction matters for investors reading the story: the directive is the permanent rulebook, the Rs 4.13 lakh figure is this year's application of it, and next year's number will be recomputed.
Until now, a private generator in Nepal effectively sold to one buyer. The power purchase agreement with NEA was the only commercially viable route to market, which meant the Authority set the price, the offtake risk sat with a single counterparty, and any generator that wanted a different buyer had no wires to reach them. Open access changes the plumbing: a generator or trader can now book capacity on the national grid, pay NEA the regulated wheeling charge, and deliver power to a third-party buyer, including, in principle, buyers across the border once trading arrangements allow it. NEA, for its part, converts from sole buyer into a regulated transmission service provider earning wheeling revenue on every unit that transits its grid. ERC member Jayaraj Bhandari added at the event that transmission charges for radial and dedicated lines outside the national grid will come under a separate directive, which leaves a visible gap: not every generator connects to the national grid backbone, and those plants wait for the second shoe to drop.
For NEPSE investors, the direct read-across is to the hydropower sector, which dominates the exchange's listed universe. Open access does not change any listed company's revenue tomorrow: no private trade has been announced, and the PPAs that underpin project cash flows remain in place. What it changes is option value. A generator with surplus energy, or one whose PPA terms are unattractive, gains a legal alternative route to market, and the wheeling charge is the variable that decides whether that route is economic. At 57 paisa per kilowatt-hour for short-term trades, the charge leaves most of the energy value with the trader and the generator, which is exactly why trading desks are watching. But the framework is still being assembled, and uptake, not publication, is the test that counts.
The question the directive leaves open is the one the market will answer over the coming quarters: does a regulated toll of Rs 4.13 lakh per MW per month open a genuine trading business, or does it price the grid just high enough that NEA remains the only buyer that matters? The Commission has built the door and published the tariff. Whether anyone walks through it, and what that does to the earnings of listed generators on either side of the trade, is now a matter of commercial arithmetic rather than regulation. Investors should watch for the first announced third-party wheeling transactions, and for the pending radial-line charges, before deciding what this reform is worth.
