The 2018 edition of the Nuclear Industry Status Report (WNISR) reveals that nuclear power capacity grew by only 1% in 2017, while wind and solar saw their share increase by 17% and 35%, respectively. The report also recognizes that solar and wind are now the cheapest grid-connected sources of energy. Investments in new nuclear plants, on the other hand, are only being driven by public support, and by nuclear weapon states.

The Sahara Desert, and the Sahel region, could be set to take advantage of large-scale wind and solar power projects covering huge surfaces.

The Uyuni project will cover half of the electricity demand in the Potosí region, and is currently the largest PV installation in the Andean country. The project was realized thanks to an investment of US$62 million.

The new Italian government has maintained, almost unchanged, the provisions for the creation of an auction scheme for solar, wind and other renewables designed by the previous government. It has, however, postponed the first auction for large-scale projects from November to January. Furthermore, it has introduced new rules to enable the replacement of asbestos covers with rooftop PV systems through an ad-hoc FIT scheme.

Tanzania-based mini-grid operator, Jumeme is tendering two 1 MW projects in the Rukwa and Katawi regions. The projects are being developed in the frame of the Micro Power Economy, Tanzania Roll out program, which is financially backed by the Africa Enterprise Challenge Fund (AECF).

Nigeria’s Rural Electrification Agency is seeking consultants to conduct feasibility studies and develop a masterplan design for the ambitious program, which aims to establish a new energy infrastructure in the state of Jigawa. The program is backed by the African Development Bank.

The mini-tender will be held under the RenovAr program for large-scale renewables, but will be limited to projects not exceeding 10 MW in size. The quota for solar and wind will be around 350 MW. Auctions for projects larger than 10 MW were suspended by the Argentinean government in early August.

In an interview with pv magazine at this year’s Intersolar SA in Sao Paulo, Rodrigo Sauaia, president of Brazilian solar association, ABSSOLAR discussed the current issues and opportunities in Brazil’s PV market. The association is calling on the Brazilian Government to contract up to 2 GW of solar power in future auctions, and to maintain current rules for DG. The private PPA segment, meanwhile, which only a year ago appeared unviable, has begun to show positive results. All in all, solar in Brazil is growing, despite the hurdles created by a difficult political and economical environment.

The parent company of Chinese solar module maker, Suntech saw its net loss almost quadruple in the first half of this year, while net revenue grew year-on-year by just 0.7%. Sales of solar products in the period reached around 1.9 GW, and the group’s total installed operational PV capacity reached 1.5 GW at the end of June.

The scientists have shown how the control of the molecular structure of a semiconductor polymer makes it possible to obtain a PV conversion efficiency of more than 10% for an organic solar cell.
