In Moscow in October 2026, during Russian Energy Week, the main design contract for the expansion of Thermal Power Plant No. 3 in Ulaanbaatar was signed. For Mongolia the signature was B. Sandujav's, executive director of TPP-3 SOE, the state plant company; for Russia it was M. E. Sergeev's, director of Inter RAO Export (Elch.mn, October 2026; TASS, 15 October 2026). Present was Minister of Energy Badrakhyn Naidalaa, who had met Russian Energy Minister S. E. Tsivilev and presented Mongolia's sector policy at the forum (TASS, 15 October 2026; Elch.mn, October 2026).
The contract was not a personal contract. The party to it is the state plant company, not the minister personally. But the file it advances is now his. The expansion would add 252 megawatts of electric capacity and 300 gigacalories per hour of heat — about 84,000 households' electricity and 30,000 households' heat, on the ministry's own figures (Elch.mn, October 2026). For a capital that must heat itself through the winter, that is not abstract. It is the plant, the heat, and the loan behind them.
This piece is not about a man taking something. On the record assembled for it, no such claim exists. It is about a structure: a minister whose own declaration is modest, against whom no court, anti-corruption or offshore-leaks finding was located, signing his country forward — by presence, by policy and by office — into a project designed in Russia and financed, on the feasibility record, mostly by a Russian loan.
Badrakhyn Naidalaa is Minister of Energy in the cabinet of Nyam-Osoryn Uchral, sworn in on 4 April 2026, where he sits for the HUN Party, listed as a new minister (Parliament of Mongolia CV, parliament.mn/cv/358, accessed 27 October 2026; Mongolia Weekly cabinet table, April 2026). Deputy Prime Minister Togmidyn Dorjkhand is the party's other senior figure in that cabinet (Mongolia Weekly, April 2026).
His route to the seat did not run through the power sector. He graduated from School No. 23 in Ulaanbaatar in 1993, took a bachelor in business administration at the Institute of Finance and Economics in 1997, lectured in economic theory there from 1997 to 2002, and took a master's in economics, in development economics, at Kobe University in Japan in 2004 (Parliament CV).
From 2004 to 2007 he was an economist and then Director of Risk Management at Anod Bank; from 2007 to 2008, Director of Risk Management at Khan Bank; from 2008 to 2011, a department director at MCS Group and Unitel LLC (Parliament CV). He then ran the sector's associations: executive director of the Mongolian Economic Forum in 2011–2012, executive director and secretary general of the Mongolian Bankers Association in 2012–2015, and executive director of the Association for the Development of Sustainable and Green Finance, known as ToS, in 2018–2020 (Parliament CV).
Politics ran alongside. He was in the HUN Party leadership from 2016 to 2024 (Parliament CV) and led HUN into the 2020 parliamentary election as party leader, in the Right Person Electorate Coalition, which won one seat, with 209,104 votes, 5.23 per cent (Wikipedia, HUN Party electoral history). On 1 October 2019 HUN executives including "Party Leader B. Naidalaa" met Constitutional Democratic Party of Japan leader Yukio Edano in Tokyo (CDP Japan archive, archive2017.cdp-japan.jp).
He became an MP in 2024, was awarded the Order of the Polar Star in 2024, and chaired the Standing Committee on Human Development and Social Policy in 2025–2026 (Parliament CV). Assa.mn reported, shortly before the change of government, that outgoing Prime Minister Zandanshatar also intended to name Naidalaa to the Energy seat after B. Choijilsuren's resignation; the appointment was in the event made by the Uchral cabinet on 4 April 2026 (Assa.mn, accessed October 2026).
The clearest window into Naidalaa's own finances is a republication of the declaration he filed as an MP with the Independent Authority Against Corruption, the IAAC, presented when his appointment to the Energy seat was announced (Assa.mn, assa.mn/a/75599, accessed 27 October 2026). Decode treats every figure there as REPORTED until the original IAAC filing is read, because the filing year is not stated on the Assa.mn page.
As republished, the figures are: own income ₮44.4 million; family income ₮81.5 million; real estate — one apartment and one summer house — at ₮710 million; two Nissan cars at ₮150 million; two horses at ₮3.5 million; two possession plots, 624 and 700 square metres, at ₮10 million; valuables at ₮180 million; savings of ₮13.7 million in domestic accounts; and loans of ₮239 million (Assa.mn, accessed 27 October 2026).
His company position is narrow and long-standing. He holds 40 per cent of SDB LLC — 120 shares — declared in his 2019, 2020, 2023, 2024 and 2025 filings, as reproduced by UIH.mn and OpenDataLab. SDB's registered activities are management consulting, economic and business research, and financial consulting. He also declares 53,200 shares in Erdenes Tavan Tolgoi JSC, widely held by citizens under the state distribution programme; no control or influence is asserted from it. No other company or shareholding in his name was found beyond SDB and Erdenes Tavan Tolgoi.
Two features deserve a plain reading, as questions, not findings. Valuables at ₮180 million are roughly four times his declared annual own income of ₮44.4 million, and roughly thirteen times his declared savings of ₮13.7 million. Those savings are also small against declared debt of ₮239 million. Neither fact is wrongdoing. Both are what a declaration system exists to have explained on the record, and both will be put to him under the reply law below.
The limits matter too. The holders of the remaining 60 per cent of SDB LLC are not established in the sources checked, and no company record for his wife was established. His wife, B. Khulan, and their three children — two daughters and a son — are REPORTED from one source (Urug.mn, 2021), and nothing further is asserted about them. No sourced reporting was found of assets or spending by Naidalaa beyond his declaration.
A negative, stated plainly, is part of the evidence.
No conviction and no court judgment naming Badrakhyn Naidalaa was located in the sources checked (Decode profile record check, 25 September 2026; engine sweep, 26 October 2026). No IAAC conflict-of-interest or declaration-violation finding, IAAC action, sanction or court case against him personally was located (sweep, 27 October 2026). In the ICIJ Offshore Leaks database there was no corroborated match (engine sweep, 26 October 2026). No OCCRP investigation naming him, no Interpol notice, and no foreign court or corporate record naming him was located (engine sweep, 26 October 2026, re-checked 27 October 2026). No foreign assets are declared; the republication lists savings only in domestic banks (Assa.mn, accessed 27 October 2026).
On the energy file the same negative holds. No company connected to Naidalaa was found holding an energy tender, a generation licence or a power-sector contract. No energy-sector activity is registered for SDB LLC. No personal, family or company connection between Naidalaa and Inter RAO was found.
That record governs how this piece should be read. The questions that follow are not about a minister's integrity, for which this record provides no basis. They are about a project, its price, its financing, and the dependence those terms create.
Naidalaa did not take over a quiet ministry. His predecessor was Battogtokhyn Choijilsuren, Minister of Energy until April 2026. In January 2026 senior officials of Thermal Power Plant No. 4 JSC and the National Power Transmission Grid SOE were detained in connection with corruption allegations, and then Prime Minister Zandanshatar gave then Minister Choijilsuren a one-month ultimatum over TPP-4 (REPORTED — Mongolia Daily / MI24 morning brief, 29 January 2026, citing Montsame and Eguur). That episode is predecessor-era, not part of Naidalaa's record, and nothing in it is a claim about him. It is the institutional inheritance on his desk from 4 April 2026. The largest contract in that inheritance was already moving.
The project is the expansion of an existing Ulaanbaatar plant, Thermal Power Plant No. 3. Its cost and financing pre-date Naidalaa. The total budgeted cost is approximately €1.37 billion — €1.40 billion including VAT — financed 85 per cent by a Russian export loan, approximately €1.28 billion, and 15 per cent by Mongolia, approximately €199 million (Global Energy Monitor, gem.wiki, Ulaanbaatar-3 power station, accessed October 2026, citing the 2022 Inter RAO Export feasibility study). Inter RAO Export is the export arm of Russia's state-controlled Inter RAO group, and the financing is a Russian state export loan — the largest foreign-state financial exposure his ministry is currently advancing.
The terms were debated before they were his. Mongolia Weekly in 2025 put the debated figure at €1.3 billion and recorded MPs' criticism that the draft design agreement "reflected Russian demands more than Mongolian laws", and that the implied cost per megawatt was comparable to building new (Mongolia Weekly, 2025). The intergovernmental design agreement was signed in September 2024 and ratified by parliament in January 2025 — before Naidalaa took the seat (Global Energy Monitor, accessed October 2026).
What falls inside his tenure is narrower: the October 2026 design contract signature, and the general construction agreement that follows it. A minister can inherit a project and still own the steps he takes on it. From the Moscow signature, the questions — what the design contract costs, what it buys, and whether the €1.37 billion total and the 85-to-15 split survived into the signed documents — are for the ministry he now leads, to be answered from documents it holds.
The structural question does not depend on any individual's conduct. An expansion designed by the export arm of a Russian state-controlled group, financed mostly by a Russian state export loan, ties a share of the capital's future electricity and heat to a single foreign creditor and design house for the life of the loan and the plant. That is energy dependence in contract terms, not slogans. Whether it is the right price for winter security is a policy judgement on which Decode takes no side. Whether the public can read the terms is a documentation question, and on this record those documents have not yet been produced.
The Russian loan is not his only policy since April.
In October 2026 he presented an "Energy Sustainable Transition Strategy 2026–2050" at the CAREC ministerial conference in Ulaanbaatar, aimed at reducing import dependence, with a first export corridor targeted from 2035 (Erchim.net, ministry outlet, October 2026). That strategy points away from import dependence over twenty-five years. The TPP-3 design contract is a signed document now. Decode records both, and notes the distance between them without resolving it.
Selection processes have also been announced for solar and battery-storage projects in five aimags, at the signing of a cooperation memorandum between the Ministry of Energy, the Development Bank of Mongolia and the Mongolian Bankers Association, where Naidalaa also flagged bond issuance and low-interest financing for priority projects (Tuuchee.mn, September/October 2026). Tender winners were not named in the source, and no company connected to him appears in it.
On winter readiness, the minister has been parliament's critic, not its defendant. On 6 October 2026 he told parliament that ₮18.3 billion approved for winter preparation had been cut from the energy budget in the 2026 amendment and 2027 budget process, and publicly criticised MPs of both large parties over the cut (Nexa.mn, 6 October 2026). Whether it is as he described it is checkable from the budget documents listed below. Elsewhere, the Erdenebüren hydropower plant is REPORTED to be about 40 per cent complete, with commercial operation scheduled for 2030 (Particle.news, 17 October 2026) — sector context only.
His first six months present two records in parallel: a stated agenda of transition, tenders and a fight over winter money; and a very large inheritance moving forward in his signature season. Neither cancels the other. The test of both is the documents.
A research return received by Decode on 26 October 2026 referred to an allegation, attributed to a source named "Ergelt", concerning HUN Party registration documents from Naidalaa's party leadership. The return supplied no document, no date, no case number and no detail of what is alleged to be wrong. Decode Mongolia has not verified this claim; it is published as reported.
First, the TPP-3 file: the main-design contract signed in October 2026, and the September 2024 intergovernmental design agreement with its January 2025 ratification file — Ministry of Energy, TPP-3 SOE, parliament ratification record, and the Glass Account (shilendans.gov.mn) for payments. These would prove the contract's value, what the design fee buys, and whether the €1.37 billion cost and 85-to-15 split survived into the signed documents.
Second, his original IAAC declarations for every filed year, 2019 to 2026 — IAAC database (xacxom.iaac.mn) and the OpenDataLab and UIH.mn reproductions. These would prove or break the Assa.mn figures, the continuity of the SDB holding, and any jump in the valuables or loan lines.
Third, a full registry extract for SDB LLC — State Registration Office and OpenDataLab — proving all shareholders and directors since incorporation, and in particular who holds the other 60 per cent.
Fourth, the five-aimag solar-plus-storage tender files — tender.gov.mn and ministry announcements: notices, bidder lists, evaluation reports, winner contracts — proving who won, at what prices, and whether any bidder connects to a declared interest.
Fifth, the winter-preparation budget execution file for the ₮18.3 billion — Ministry of Finance amendment documents and Glass Account lines — proving what was cut, from which programmes, and what it bought in prior years.
Sixth, the original Ergelt material, with the Supreme Court party-registration file for HUN for the relevant years — documents that would prove or kill the allegation above.
Seventh, his 2024 election-campaign finance report (General Election Commission) and HUN's audited party-finance reports for 2016–2024 (National Audit Office), proving donors and spending during his leadership.
Eighth, his Standing Committee chair record for 2025–2026 (parliament.mn committee minutes) — career context, with no wrongdoing angle asserted.
Under Decode Mongolia's reply law, Minister Badrakhyn Naidalaa will be contacted in writing before publication. He will be given each material claim this piece intends to publish — the Assa.mn declaration figures, the valuables question, the SDB holding and its remaining 60 per cent, the TPP-3 contract and financing questions, the five-aimag tender questions, his statement on the ₮18.3 billion cut, the existence of the unverified Ergelt allegation, and the negative court and IAAC record — and he will be invited to answer with documents, within a deadline named in that letter. His answer will run beside the piece when it is published. Any claim that a document he provides proves false will be relabelled proven false, with the proof linked. No contact has been made for this draft, and nothing in it has been published.
