Meeting our energy needs

Secure, long life and competitively priced electricity supply is vital in the aluminium industry.

Rio Tinto Aluminium owns 13 power stations with an annual capacity of over 6,100 megawatts. This meets about half of our electricity needs, a proportion well above the industry average. Our long‑term power purchase contracts account for a further 46 per cent of our electricity supply.

Applying international standards

All of our sites are certified to the international environmental standard ISO 14001 (International Organization for Standardisation). All newly acquired or commissioned sites are required to be ISO 14001 certified within two years.

We consistently apply these standards across our organisation. Our sites are audited regularly by independent accreditors to identify areas for potential improvement.

  • Air quality
  • Closure and areas under management

These programmes help us:
