Attribuée à Voltalia via un appel d’offres public lancé en décembre 2022 et soutenu par un contrat d’achat d’électricité (PPA) de 25 ans, la construction d’une centrale solaire de 126 mégawatts, située à Sarimay, dans la région de Khorezm en Ouzbékistan, est arrivée à son terme.

Financé par la Banque Européenne pour la Reconstruction et le Développement (BERD) avec le soutien du Fonds Européen pour le Développement Durable Plus, ce projet de 180 hectares intègre plus de 180 000 panneaux solaires bifaciaux, plus de 350 onduleurs et une ligne de transmission de trois kilomètres. Une fois pleinement opérationnelle, la l’installation produira environ 252 gigawattheures par an – de quoi alimenter 60 000 habitants – et permettra d’éviter plus de 140 000 tonnes de CO₂ chaque année.

Voltalia a piloté le projet depuis la phase de développement jusqu’à la supervision de l’ingénierie, de l’approvisionnement et de la construction (EPC) ainsi que la maintenance prévue dès la mise en service complète de la centrale.

À noter que le producteur développe un deuxième projet majeur en Ouzbékistan : Artemisya, un complexe hybride de 500 hectares, dont la première phase prévoit 100 mégawatts d’énergie éolienne et 100 mégawatts / 200 mégawattheures de stockage. Le début de la construction est prévu en 2026, avec une mise en service fin 2027. La capacité de production d’Artemisya est estimée à 383 gigawattheures par an.

First concrete for Uzbekistan SMR 'well before December'

Wednesday, 28 January 2026

Uzbekistan President Shavkat Mirziyoyev and Rosatom Director General Alexei Likhachev have discussed progress on the project to build a nuclear power plant featuring both large and small reactors.

According to the president's news service the two also talked about "expanding cooperation in the peaceful use of nuclear energy", in areas such as agriculture and medicine.

First concrete for the first small modular reactor had been expected to be poured in the spring, but a draft government document published last week mentioned December 2026.

That led to the Uzatom Agency publishing a clarification on Monday saying: "We would like to emphasise that the previously announced targets remain in effect, and there is no discussion of any postponement. The date indicated in the draft reflects a conservative scenario, which envisages the completion of all numerous mandatory preparatory and licensing stages by this date."

Following the talks on Tuesday, Likhachev said: "We are moving forward at a rapid pace and fully on schedule. Work on site is proceeding actively ... this year's main goal is to begin pouring concrete for the foundation slab of the nuclear island buildings. Given the importance of meeting deadlines, we aim to begin concrete preparation work this spring."

In a subsequent interview with Russia’s Rossiya-24 television channel, as reported by the official Tass news agency, he said: "I think we will pour the first concrete … much earlier than December. Our speed will depend on the customer … this is a regulated event implying receipt of certain licences, permits, qualifications, including for local manufacturers. Nevertheless, our plans are to make it much earlier than December."

Excavation work began in October for the pit for the first of the SMRs at the site in the Jizzakh region. About 1.5 million cubic metres of soil will be excavated during the digging of a pit 13 metres deep for the RITM-200N, with engineering surveys and design and preparatory works also under way.

Uzbekistan and Russia mark SMR construction progress

Tuesday, 24 March 2026

Russia and Uzbekistan have signed a roadmap for nuclear cooperation, as initial concrete was poured as part of preparations for the construction of the first small modular reactor at Uzbekistan’s first nuclear power plant.

The roadmap, signed by Rosatom Director General Alexey Likhachev and Uzatom Director Azim Akhmedkhadzhaev, "covers all key areas of cooperation on the nuclear power plant construction project, including personnel training, public awareness of modern nuclear technologies, and the creation of a future 'nuclear city' at the plant".

A supplemental agreement to the contract for the new nuclear power plant covers the decision to change its contents to two gigawatt-scale VVER-1000 units and two 55 MWe RITM-200N small modular reactors (SMRs). The original plan had been for the plant to feature six of the SMRs - the new design will mean a capacity of more than 2,100 MWe, compared with the previous 330 MWe.

The two countries' presidents spoke on the phone on Tuesday, noting the signing of the roadmap and the progress being made for the first SMR unit at the site, in the Jizzakh region.

Rosatom said that, following the receipt of the necessary permissions to use the site for the two SMRs, concrete work had begun at the site, saying that "approximately 900 cubic metres will be poured during the concrete foundation work for the reactor building, due for completion in April". It said that this foundation will then be levelled and waterproofed before "the pouring of the first concrete for the reactor building's foundation slab".

Uzbek uranium mine enters commercial production

Thursday, 23 April 2026

Navoiyuran has announced the start of commercial in-situ uranium recovery at the Qizilkok deposit, located in the Navoi region of Uzbekistan.

"Pilot industrial operations at the deposit began in December 2024, and over two years of active work, the Company has reached the stage of commercial production," said Djamal Sabakhonovich Fayzullayev, General Director of Navoiyuran. "The start of ore mining at the deposit marks another step in the implementation of the company's strategy, focused on increasing uranium production and strengthening its mineral resource base, in line with Uzbekistan's state programme to expand uranium mining and processing volumes through 2030.

"In 2025, Navoiyuran's production reached 7,000 tonnes of natural uranium. The Qizilkok deposit, with a projected mine life of 15 years and an annual production capacity of 1,200 tonnes of uranium, will play a key role both in supporting future production growth and in contributing to regional economic development."

The Qizilkok prospective area - situated in the eastern part of the Central Kyzylkum Desert - comprises four licence blocks: Amantau (in the northwestern part), Myutenbay (in the northeastern part), Qizilkok (in the southeastern part), and Yuzhny (in the southern part). Under the project, all of these licence blocks are integrated into a single prospective area, Qizilkok.

The Qizilkok deposit is being developed using a low-reagent in-situ recovery oxygen technology actively advanced by Navoiyuran, which it says increases uranium recovery while reducing production costs by 2-3 times.

In-situ recovery - or ISR - is a method of mining uranium by dissolving and recovering it via wells. It is also known as in-situ leaching. Ground water fortified with a complexing agent, and often with an oxidant (such as gaseous oxygen), is introduced into the orebody to dissolve the uranium from the sandstone host. The uranium-bearing solution is pumped to the surface before the uranium is recovered and processed into yellowcake.

Navoiyuran describes Qizilkok - with mineral resources of 10,900 tU and ore reserves of 9,400 tU - as the third-largest deposit in its portfolio, following the Sugrali (20,800 tU of reserves) and Uchkuduk (14,800 tU of reserves) deposits. It has a project mine life of 15 years, with further potential for expansion to the north.

Uzbekistan's estimated uranium output in 2024 was 4,000 tU, according to information from World Nuclear Association, making it the fifth largest uranium producer in the world behind Kazakhstan, Canada, Namibia and Australia. Navoiyuran says it is currently the sixth-largest uranium producer globally, operating 43 uranium deposits with a mineral resource base of 151,100 tU, including 96,600 tonnes of JORC-compliant ore reserves.
