WACC draft decision constrains Vector investment
The Commerce Commission has released its draft decision on the proposed amendment to the Weighted Average Cost of
Capital (WACC) percentile, recommending a decrease from the current 75th percentile to the 67th percentile.
This change would reduce the allowable return on our assets when all previous investment decisions have been based on
the returns we would expect from a 75th percentile. A WACC setting at the 75th percentile is a position long-held by the
Commission.
The draft decision reduces the investment returns from the network and, when added to other approaches by the
Commission, places further pressure on our ability to invest in network sustainability and growth.
Current technology advances greatly increase risk and uncertainty in network investments, which should be increasing the
allowable return on assets or WACC percentile, not reducing it.
The correct balance between lower prices for consumers and a suitable return on investment in the network is critical to
maintaining the long-term, security of supply that is essential for Auckland’s growth and success.
The Commission has exercised considerable discretion in proposing the 67th percentile in light of two of its independent
expert advisors recommending the status quo or higher percentiles.
Vector continues to engage with the Commerce Commission on the draft WACC percentile decision.
The draft decision can be found on the Commerce Commission website.
