European Tribune

Display:
I wrote to Chris with some questions and am posting his answers here:

marco: 2628 MWH is 30% of 8760 MWH.  But where did that latter figure come from?  Does it somehow come from it being a 1 Mega Watt wind turbine?

ChrisCook: One Unit is 10 Kilo Watt Hours: therefore  100 Units = 1 Mega Watt Hour

In other words, it should have occurred to me that there are 8760 hours in a year.

marco: Also, the 1000 MWH (i.e. 1,000,000 Units) per year gets paid to the "Operating Member" -- that is, the entity that built the wind turbine -- is that correct?

ChrisCook: No. This 1m Units per year of production goes to the Pool in repayment of what is essentially a "Loan" repayable in Energy Units rather than dollars.

The entitlement to the output is split proportionally between:

(a) the Developer/Operator - maybe 10 to 20% of output;

(b) the Land Owner - (who probably is the "Community"), and certainly needs the Community's permission;

(c) the Investor - ie the Pool

(d) the Community

The "Community" is a broad term. It could have the skills to be the Developer.


marco: I imagine the "Pool-Manager-formerly-known-as-Investment-Banker" would get a cut as well, right?

ChrisCook: Yes, He will be part of  the Developer/Operator consortium.


marco: Which would leave 1628 MWH, minus the Pool-Manager-formerly-known-as-Investment-Banker's share, to the developer/land owner/community who owns the turbine.

These may then be redeemed for renewable energy consumed; against repayment of Pool investments used to achieve energy savings (so-called "Nega Watts"); or he may just sell them off at the market price.

Could you explain what the first two mean in practice?

ChrisCook: Units are essentially "tickets" or IOU's redeemable by the Community ownd turbine against electricity production at the retail price. So, yes they would be used to "pay for" renewable energy.  When you get billed by your power supplier, you pay in both dollars, and in tickets. The power supplier (an intermediary) then pays a renewables producer with them.

It doesn't matter what source your electricity actually came from.

The key point is that using this mechanism, renewables and energy savings are literally "self funding".



Truth unfolds in time through a communal process.
