Powering the planet

Electricity is the modern lifeline

Electric power is so much more than switching on a light bulb, and the havoc wreaked by hurricanes Irma and Maria in September was a stark reminder of this.

Here comes the sun

Solar PV on the cusp of becoming widespread

Solar photovoltaic (PV) electricity is rapidly increasing its share of global power generation. Technology and production breakthroughs are making it cheaper to manufacture. The IEC is leading the way with the appropriate International Standards.

Flexible hydro operation for lean integration of new renewables

Hydropower helps incorporate the growing share of intermittent renewable sources into the energy mix

In 2015, global generation of electricity was 24 255 TWh. Hydropower accounted for around 16% of the total, making it the main renewable energy (RE) source for electricity generation. It will also play a key role in the future integration of power generated by new RE sources and in balancing its impact on the grid.

Expanded pumped storage power station goes into service

IEC experts, e-tech, visit new Veytaux pumped storage plant

Electricity is consumed predominantly as it is produced. Electricity generation relies increasingly on new renewable energy (RE) sources, mainly sun and wind. These are intermittent and not always available when needed, so electrical energy storage (EES) becomes essential in integrating them successfully into the energy mix. Pumped storage is by far the largest-capacity form of EES available, representing around 95% of the total available globally, according to the US Department of Energy Global Energy Storage Database

Keeping mature technology in top shape

Proper repair, maintenance and overhaul are essential to keep hydro installations running

With the share of RE (renewable energy) sources in the global energy generation mix predicted to grow considerably in coming decades, hydropower will continue to make a major contribution to clean energy production. Cost estimates for hydropower installations still tend to focus on equipment and construction expenditure. However, long-term lifecycles and the need to improve efficiency require extensive MRO (maintenance, repair and operations/overhaul) work that carries additional significant cost implications.

Supporting rural electrification

IEC series of publications to help rural populations in developing world access electricity

Hundreds of millions living in rural areas in developing countries are without access to electricity, a prerequisite to human and economic development. Off-grid renewable energies offer an attractive solution for these people. The IEC has issued a series of publications for small renewable energy and hybrid systems for rural electrification, which is available at a discounted price in a joint initiative with the World Bank Group and the United Nations Foundation.
