I think this 'homes' description is really misleading, because I bet people confuse 'powering all the homes in Glasgow' with 'powering all Glasgow's electricity' or even 'powering all Glasgow's energy'.

Let's do a simple calculation.

The average expected power from Glendoe is 180 GWh per year [source]. Now

if we take 180 GWh per year and share it between a Glasgow of people

(616,000 people), we get 0.8 kWh/d per person.

OK; what is the average electricity consumption per person (including all forms of electricity, not just domestic)? Answer: 16 kWh/d per person. So Glendoe actually provides

**5% of the electricity consumption of Glasgow**.

So if people get the impression from the press releases that Glendoe will power Glasgow, they have been misled

**by a factor of twenty**!

This is a bigger factor than the normal factor by which people are usually misled. The statement

that Glendoe (180 GWh/y) would power 250,000 homes implies that each 'home' uses just

**720 kWh per year**. But the normal assumption in press releases about wind or tide is to assume the average home uses

**4000 kWh/y**or

**4700 kWh/y**. What's going on? The ratio between 720 kWh and 4000 kWh (18%) is suspiciously similar to the ratio between the average power production of Glendoe (180 GWh/y) and its capacity (100 MW is equivalent to 877 GWh/y). Methinks that someone at Scottish and Southern must have screwed up (or deliberately misled the public) by pretending that Glendoe will produce 100MW 100% of the the time, whereas in fact it will have an average load factor of 20%.
