two bearing AVR controlled versions. Permanent magnet generator (PMG) technology is fi tted as standard, and the range’s 2/3 pitch windings avoid excessive neutral currents. T e generator sets into which the alternators are fi tted are actually a rental-spec design. However, thanks to the durability of their components and their ability to operate reliably in the harsh environmental conditions of the project, the customer felt confi dent in purchasing the generator sets outright. Support, service and a commitment to delivering and setting up in a short time frame were further key factors in the decision to purchase. T e 1,250 kVA generator sets, equipped with Cummins KTA50-G3 engines, provide 37.5 MVA of power and operate 24/7 from two plants, each supplying 18.75 MVA. Each plant is equipped with 15 x C1250 D2R units for prime power, 15 x 0.4 kV/11 kV step-up transformers, two 20ft containerised MV cells including
The project relies on 30 generator sets to ensure it keeps running
Digital Management Control system and MV switchgear. T e Ambatovy Project is already contributing greatly to the local economy – around 12,000 workers were hired directly and indirectly during the construction phase alone. A local development programme provides a human resources registration centre with occupational and technical training programmes for small- to medium-sized local companies. More than 200 public hearings were held to examine the project’s social and environmental issues, which led to the adoption of environmental conservation models based on World Bank guidelines. ●

AWARD FOR AMBATOVY A
mbatovy has won the 2015 Syncrude Award for Excellence in Sustainable Development for having successfully implemented a range of solutions for sustainable development in Madagascar. The award, issued by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), acknowledges companies or individuals that are “active seekers of sustainability solutions.” At a ceremony in Montreal on May 11,2015, Sherritt International, Ambatovy’s operator, received this award.
Ambatovy strives for sustainable development in the communities where it operates as well as in its host country through the implementation of several programmes, including a biodiversity management programme that targets ‘no net loss’; a ‘buy locally, hire locally’ policy that is supported by leading-edge initiatives; agricultural skills training for more than 18,000 people from local communities, developmental partnerships with international organisations; and innovative
archaeological and retrenchment programmes. The Syncrude Award is the
fourth sustainability award Ambatovy has received in the past 18 months. The other awards include: Nedbank Capital Sustainable Business Award for Ambatovy’s biodiversity programme; Excellence in Corporate Responsibility Award for the Ambatovy Local Business Initiative; UNAID’s Good Practice Award for Ambatovy’s contribution to the fi ght against HIV/AIDS in Madagascar. ●
