New case study video: Australian Grid Operator

According to Sebenzana APP’s Dave Tarrant, while Western Australia has been good at implementing renewable energy projects to replace coal-based electricity generation plants, the cleaner technology does have a downside – a lack of inertia to stabilise the power grid. As a result, a “perfect storm” caused the region to suffer a major power outage.

The South African towns where electricity supply is privatised

It’s hard to imagine – four small rural towns in South Africa where the electricity grid is in “very good condition”. Achieving this has seen the municipality they fall under invest an average of around R11 million to upgrade the network every year for the last 11 years (a total of R120 million).

Opinion: Sasolburg power station turnaround offers hope for keeping lights on

In this opinion article, Sasol senior VP for the Sasolburg & Ekandustria operations Rightwell Laxa, and Sebenzana MD Andrew Carr, argue that old, coal-fired power stations similar to those used by Sasol and Eskom could achieve a much-needed maintenance turnaround by blending dwindling engineering expertise with a high-tech, asset management platform. The authors outline how boiler-tube failures at the Sasolburg power stations were reduced by more than 66% and how the old power stations are now achieving world-class performance levels.

Solar PV rooftops to help meet energy targets

Viet Nam has favourable conditions to develop solar energy across the country, but according to experts, it needs an economical, technically feasible net-metering scheme to promote solar PV rooftops in the country.

Net-metering is a system in which solar panels or other renewable energy generators are connected to a public-utility power grid and surplus power is transferred onto the grid, allowing customers to offset the cost of power drawn from the utility.

It also allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated.
