The purpose of a contract price adjustment (CPAP) formula is to provide a clear-cut, agreed method for contractors to claim reasonable reimbursement for fluctuations in labour and material prices. The Joint Building Contract Committee (JBCC) has designed the CPAP to reflect the movement of these prices as closely as possible to actual cost fluctuations […]
The constant increase in demand for electrical power around the world requires more generating capacity to be installed for both local and national use. One of the most efficient and controllable sources of energy is produced by aero-derivative gas turbine engines which are employed in combined cycle gas turbine (CCGT) power plants. Aero-derivative engines […]
StorEdge and Tesla Powerwall installations have begun in South Africa. Through the distributor Rubicon, both Bright Black and Kwikelec have installed new systems, and Herolds Electrical is planning to install a demo system. Bright Black apparently installed a 3 kWp system recently that includes nine power optimisers, one StorEdge inverter, and a 6,4 kWh Tesla Powerwall. […]
Powermode has launched a locally designed and manufactured GSM cellular-based monitoring system to improve the reliability and efficiency of standby power systems in corporate environments. The Powermode Monitoring Portal (PMP) is an internet-linked system geared to monitor a company’s standby power environment, reporting on a range of critical parameters associated with uninterruptible power supply […]
The business case for solar photovoltaics (PV) in Africa is stronger than ever thanks to rapidly declining technology costs, according to a new report released by the International Renewable Energy Agency (IRENA). Solar PV in Africa: Costs and Markets, estimates that installed costs for power generated by utility-scale solar PV projects in Africa have […]
Opening the Gartner ITXPO 2016 in Cape Town on 25 September 2016, Peter Sondergaard, Gartner senior vice president and head of research, said that companies have to become bimodal if they want to successfully transform their business to compete in the digital world. He was delivering the keynote address at the conference entitled “Building […]
Several global trends are catalysing the distributed energy market. Increased electrification, decreasing costs of solar photovoltaic (PV) power generation, higher wind power and battery storage, and strong carbon emission reduction initiatives in developed countries are expected to drive revenues that stood at $59,41-billion in 2015 to $65,39-billion by the end of 2016. The largest […]
Electrical switchgear engineers NOJA Power recently announced that one of its European distributors, Vilnius, Lithuania-based systems integrator, FIMA, has installed two of the company’s OSM38 automatic circuit reclosers (ACR or “auto recloser”) as part of a modernisation program for Soviet-era electricity distribution grids in the Baltic states. FIMA designs intelligent engineering systems and tailor-made solutions […]
If you’re in IT, you probably recoil when you hear the words “backup and recovery”. Not because you don’t believe in the necessity of these processes, but rather because they can involve hours upon hours of work, at the end of which you probably still don’t feel 100% comfortable with your business’s backup plan. […]
Renewables, including hydro, now account for over 30% of the total global installed power generation capacity and 23% of total global electricity production. In the past ten years, wind and solar PV have witnessed an explosive average annual growth of 23% and 50% respectively, although their combined contribution to the global electricity supply is […]
