Oversupply In Power Sector Driving Investment Overseas
BMI View : We believe Mighty River's announcement to temporarily halt development of the Puketoi Range wind farm and other generation projects indicates a situation of oversupply in the market which is unlikely to be resolved anytime soon. In our opinion, Mighty River is shifting its investment focus to more promising markets overseas such as Chile due to the country's favourable economic and demographic trends.
On June 7, New Zealand utility Mighty River Power announced that it had been granted a final resource consent to build a 310MW wind farm in the Puketoi Range, but said that it would not begin construction for at least three years. The company also said that it was unlikely to start any new generation projects in the next three to five years, mostly due to an over-construction of gas, wind and geothermal power stations over the past decade. Might River produces about one-fifth of the country's electricity needs, and was partially privatised by the government in May 2013.
We believe Mighty River's announcement to temporarily halt development of the Puketoi Range wind farm and other generation projects indicates a situation of oversupply in the market which is unlikely to be resolved anytime soon. Electricity consumption in the country has remained relatively stable over the past decade - growing 1% per annum on average between 2006 and 2010 - and appears likely to remain on this trajectory over our forecast period. However, a number of sizeable power projects came online in the past decade, leading to a slight surplus in electricity supply over demand. Additionally, several more power projects are in various stages of development, and the completion of these projects could further widen the gap between supply and demand.

At present, we have over 2.2GW of power projects in various stages of development recorded in our Projects Database, and the completion of these projects would increase the installed capacity by over 20% by 2022, exceeding the growth in electricity demand. We note that not all of these projects will be completed on schedule as the rights to these projects belong to Mighty River. One of the projects is Mighty River's 180MW Turitea wind project near Palmerston North, which we believe will be delayed given the announcement. Mighty River also recently applied to begin exploratory drilling for the Te ia a Tutea project on the Taheke geothermal field, and we expect this project to also face delayed. That said, we still expect a comfortable buffer in electricity supply over demand to be maintained over the coming years, even after Mighty River's decision to delay development of its projects.
In our opinion, Mighty River is shifting its investment focus to more promising markets overseas. In late-May, a Chilean unit of Mighty River, MRP Geotermia Curacautin Ltda, was awarded an environmental permit for the 70MW Curacautin geothermal plant in central Chile (see 'Vast Renewables Potential Ready To Be Tapped', June 4). The Chilean energy market is extremely attractive given favourable economic and demographic trends, and we believe that Mighty River will continue to focus on the market and other similar markets in the near- to medium-term until the New Zealand power market regains its attractiveness.
