EOFY2022 and we have the the former Tilt NZ based windfarms and the first stage of the Turitea wind farm 'on the books' and generating.
Mercury Windfarms EOFY2022 Commissioned Generation Capacity Waipipi 2021 133MW Tararua I & II 1998,2004 68MW Tararua III 2007 93MW Mahinerangi I 2011 36MW Turitea North 2021 119MW Total Completed Capacity 449MW
Capacity generation will not be achieved unless all of the windfarms are running 24/7. This isn't going to happen. So I will use a capacity reduction factor of 43.2% (see post 1321) to account for this. Combining this information with other information on existing hydro-electric and geothermal energy generation capacity and utilisation gives us an EOFY2021 picture.
Generation Asset Class Existing Generation Capacity Usage rate Effective Generation Capacity Hydro 1063MW 51.4% 546MW Geothermal 463MW 94.0% 435MW Wind 449MW 43.2% 194MW Total 1175MW
The yet to be constructed Turitea 2 is designed to deliver 103MW of generation capacity, or
103MW x 0.432 = 45MW of effective generation capacity
With the equivalent of seven of these stations already funded to be constructed (post 1460), the incremental value embedded in Mercury shares which is already embedded above existing production capacity is:
1 + (7 x45MW)/(1175MW) = 1.268 or +26.8%
Giving value to some of Mercury's own consented power stations, which apart from Turitea South, have not been given the go ahead yet is a strange concept. But it does appear the market is doing just that. Because IMO, the current MCY share price is very difficult to justify on Mercury's earnings today. My explanation is that 'everyone needs power' and the country is on the path of 'renewable electrification'. So even though not all of the Mercury consented power stations are yet built, there is reasonable certainty that they will be. And people are prepared to pay for 'certain cashflow', even if it is a few years away.
