Review of the Independent Engineers’ Reports on the Asset Adjustment Process of Electricity Distribution and Gas Pipeline Businesses - New Zealand


The asset adjustments modify the way the valuation approaches were applied when the most recent Optimised Deprival Valuation was undertaken as part of the default price-quality regulation for regulated businesses in New Zealand. After successfully completing the review for Non-Exempt Electricity Distribution Businesses, NCL undertook the review for Gas Pipeline Business (gas distribution and transmission), and then also for Exempt Electricity Distribution Businesses. The three projects involved undertaking the review and providing advice to the Commerce Commission on the engineering reports submitted to support the asset adjustments and recommending prudent changes to the regulatory asset base of the regulated businesses.
