Electricity + Control

View icon maroon

Electricity and Control July 2017Our lead story in the July 2017 issue, Temporary Power as a Free Agent in Complex Adaptive Systems, by Nalen Alwar of Altaaqa Global Caterpillar Rental Power, shows how important it is for parastatals to recognise the potential contribution of free-agents represented by fast track technology and solutions for provision of power to aid system performance. Altaaqa Global recently set up office in Southern Africa with its head office in Johannesburg.

Hmm… Could there be ‘winds of change’ at Megawatt Park? Is Eskom about to return to being the South African electricity public utility rather than an ‘embattled parastatal, plagued by allegations of fraud, corruption and mismanagement’? Time will tell… problem is, time is running out! We say… all the best to Johnny Dladla, newly appointed Acting Chief Executive of Eskom.

And… is there something in this industry that is fascinating or bothering you? If so, Electricity+Control would like to invite you to submit 350 words on the topic… ask the questions… probe the answers. Your article may be published in our new feature called ‘Write @ the Back’. Silvana Claassen of CES South Africa, in our first ‘Write @ the Back’, asks: How can owners of sectional title units in security complexes reduce their personal carbon footprint?

Enjoy the read!
