@SkyPunter is on the money. You have sadly shown you have no clue or ulterior motive.
$500M is total cost of the plant. NWE share is $100M (20%).
In the revised revenue scenario put forward by skypunter
65361111 If you have a projected revenue stream of $2.6 billion for the whole thing, thats around $500M per annum for NWE's 20% share.
The banks will be falling over themselves to get your business...even if you pay a premium interest rate, it gets paid within a year of production ($500M per year revenue V $100M loan).
