Independent power generation in Southern Africa

  Independent power producers (IPPs) are mainly understood to be renewable energy projects and the main programme, the Renewable Energy Independent Power Producers Procurement Programme (REIPPPP), has focussed on this sector. There are however other IPP programmes, focusing on small coal and gas powered sites, as well as a number of private generation projects. The […]

Biogas specialist acquires additional refineries

The Weltec Group has acquired two biomethane refineries in Hesse and Saxony-Anhalt in Germany. The plant in Hesse produces 1000 m³/h of raw biogas which it converts to 550 m³/h of biomethane.  This gas is then distributed on Germany’s public natural gas grid. In addition to the purchase of the biomethane refinery in Hesse, the company […]

Floating wind turbines and substation

  Fukushima Shinpuu, the largest floating offshore wind turbine in the world – with 7 MW output capacity – is moored off the Japanese coast near the port of Onahama. The rotor blades reach a height of 188,5 m and the hub is 105 m above the surface of the sea. It took five tug boats […]

Positive demand side management: balancing renewable energy sources

  Demand side management (DSM) is normally associated with encouraging or forcing a reduction in maximum demand to enable a constrained generation capacity to match demand. However, the introduction of variable renewable energy sources into many grids has resulted in times where generation capacity far exceeds demand for short periods, stressing the generation fleet as […]

Significant growth reported in renewable energy investment and usage

  Renewable energy continued to grow in 2014 against the backdrop of increasing global energy consumption, particularly in developing countries, and a dramatic decline in oil prices during the second half of the year. Despite rising energy use, for the first time in four decades, global carbon emissions associated with energy consumption remained stable in […]
