The current mix of generation in the grid comes from Energy Market Services – a service provided by Transpower.
Current emissions shown are only generation emissions, and exclude embedded emissions.
We calculate emissions using the emissions factors from a number of sources as no single source exists for all generation types. The 2014 emissions factor for geothermal, coal and gas is published by MBIE. The factor for diesel is unpublished but is based on average diesel emissions over the past 10 years. The emissions factor for co-gen comes from EnergyLink, and excludes Kinleith’s wood fired station. Hydro and wind are rated at zero.
