The cost of electricity from a new-nuclear build in SA under various assumptions

  Following an analysis of the cost of electricity from Eskom’s new-coal build programme in South Africa (Medupi and Kusile coal-fired power plants), several requests have been received for a similar analysis to establish the levelised cost of electricity (LCOE) from the proposed 9,6 GW new-nuclear build programme in South Africa under various assumptions. This […]

Understanding the cost of electricity from Medupi, Kusile and IPPs

  In order to understand and compare the cost of electricity from a power plant, whether it is coal-fired, nuclear, hydro, gas, wind or solar, one needs to look further than simply the capital, fuel or operating and maintenance costs in isolation, to a concept known as the “levelised cost of electricity” over the lifetime […]

Developments for improved internal combustion gas engines

  Reciprocating internal combustion engine-based generators are among the most mature distributed generation technologies available, accounting for a high percentage distributed generation installations. With the promise of cheaper and abundant gas supplies, gas fired internal combustion engines are being used increasingly for power generation, especially from renewable gas sources. Although the basic internal combustion engine […]

Rail system gives a new slant to gravity energy storage

  Advanced rail energy storage (ARES) are developing a gravity based energy storage system which uses above-ground plant consisting of railway lines and loaded shuttle rail trucks. The system is claimed to be able to provide both active and reactive power in wide range of capacities, at a lower cost than pumped water storage (PWS). […]

Rosatom to launch world’s first floating nuclear power plant

  In 2019 the world’s first floating nuclear power plant “Akademik Lomonosov” will begin operation in the most northern part of Russia. But in reality it can be operated anywhere around the world. The floating nuclear power plant is a mobile power unit, providing energy generation where and when needed. “Akademik Lomonosov” producers above 70 […]
