Energy management Standard ISO 50001 – early adopters report major gains

Issue 30 – August 2011

Evidence that publication of ISO 50001:2011 was eagerly awaited is borne out by the number of organisations worldwide claiming to be the first in their country or sector to have adopted the new international Standard on energy management. Several organisations are already reporting significant benefits and energy cost savings from their early ISO 50001 implementation.

Implementation of ISO 50001 is gathering pace worldwide and five early adopters discuss the gains to their organisations from ISO 50001 as follows.

Renewable energy generation on the increase

Issue 30 – August 2011

Renewables now make up 79% of New Zealand's electricity generation, according to the Ministry of Economic Development's latest Energy Quarterly.

Strong hydro inflows and generation from new wind and geothermal sources has seen renewable energy generation increase from 74% to 79% in the March quarter. A high level of renewable generation and the use of gas over coal at the Huntly Power Station has also resulted in the lowest quarterly electricity emission in 10 years.

'The Solar Promise' – nationwide campaign launched

Issue 30 – August 2011

On behalf of Kiwis facing higher energy costs, the Nelson City Council, Nelson Environment Centre, and SolarCity launched a nationwide campaign on 11 July 2011 – 'The Solar Promise'. The campaign encourages all New Zealand councils to embrace solar energy and help protect their communities from the rising costs of electricity and continuing oil depletion. The campaign calls for councils, central government, individuals, and businesses to do what they can to make solar energy more affordable, to help New Zealanders save money, and combat climate change.

Global smart meter sector – substantial growth anticipated

Issue 30 – August 2011
