<div dir="ltr">Cheers James and Bevan.<div><br></div><div>And I assume the "super high price" for electricity is substantially higher than the cost of running the generators in that period (ie capex/depreciation + cost of diesel < cost of power)? Can you comment Bevan on if its close, or far away from utility power costs in general? as in its obviously more expensive to power the DC via diesel long term (either due to raw fuel cost or with generator costs included), but how close is it? and further, how much of a bet/risk is it to purchase the cheaper power with these restrictions (having to go off-grid or else pay a premium)? </div>
<div><br></div><div>I'm guessing its probably a case of using historical data and just match things up to work out how many days per year on average, the cost of diesel and generators during that period, and making sure its less than the X% more per year paid for utility power with no usage restrictions, ?</div>
<div><br></div><div>Might be another thread for this, or even off-list, but I'd imagine listers would find this interesting or useful.</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Jan 15, 2014 at 11:30 PM, Bevan Slattery <span dir="ltr"><<a href="mailto:bevan@slattery.net.au" target="_blank">bevan@slattery.net.au</a>></span> wrote:<br>
