Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
Environmental Aspects of Grid Interconnection
Overview
Construction and operation of transmission grid interconnections, and the power plants that feed them, have impacts (both positive and negative) on the local, and sometimes regional and global environments. In addition, transmission grid interconnections will affect the generation of electricity in the receiving country, and also, possibly, the production and use of other fuels.
Evaluating and Accounting Impacts
Evaluating and accounting the full-fuel-cycle environmental impacts of grid interconnections is an important element of the overall process of evaluating grid interconnection opportunities. Impacts and benefits may occur at any or all points in the fuel chain, from extraction of fuels for electricity generation, to construction and operation of plants and construction and operation of transmission facilities. Environmental considerations have sometimes received less emphasis in energy planning in general than technical, economic, and (often) political issues. In the case of grid interconnections in developing regions, however, the early consideration of environmental impacts in evaluating interconnection options will help to identify key potential problems (including sensitive ecosystems to be traversed by the power lines) as well as potential opportunities that could enhance the interconnection project - including credits for avoided air pollutant and greenhouse gas emissions.[1]
Affected Areas
Grid interconnection can have both positive and negative potential environmental impacts on[1]:
- Air pollution
- Water pollution
- Solid waste
- Land use impacts
- Wildlife/biodiversity impacts
- Human health impacts
