Talk:Regenerative brake More Wikispam from Gilles.

User Ylian, contributed to Quasiturbine-related articles over a period of three days and not heard from since, User:Ylian page says they're on the US west coast, but from Talk:Quasiturbine: I think you need to put the message at:User talk:Ylian, all the anon ip's seem to be this person (Montreal, CA). By the way, this user has re-licenced the images to GFDL and appears to be on the patent. Duk 20:16, 10 Dec 2004 (UTC). If they're really from Montreal, the relationship to Gilles is an interesting question.

Wind farms

Stateline Wind Project (my contribution!)
American Wind Energy Association definition of availability factor... which specifically excludes the question of whether the wind is blowing!
ABC:
- Interview stating that there's 2,000 megawatts of potential inland in South Australia, Victoria and parts of New South Wales... =two units of a big thermal station...
- Interview re green opposition to wind at Ballarat
  - announcement (not ABC) of that project
Hydro Tasmania
Vestas wind turbine manufacturer
Environment Victoria site
Pacific hydro site
- Codrington Wind Farm actually gives cost and annual output in GWh!

Capacity factor etc

There are about 8766 hours in a year (that's the average over four years, with one a leap year), so a 1 MW unit with 100% availability and 100% load factor would deliver 8.766 GWh in a year.

Portland stage one is expected to deliver 90 GWh per year, so that's a little under 10.3 MW, for a 30 MW plant, where you'd expect a fossil or nuke plant of 30 MW to deliver more than twice that.

Portland overall is 195 MW to produce 500 GWh p.a., which is very close to 57 MW.

Or to put it another way, the rated maximum output of Portland will be 195 MW, but to produce the same amount of electricity in a year from fossil or nuke assuming 80% availability, you'd only need 71.3 MW of installed capacity.

UK DTI site discussing some terms.
Another DTI page using the term DNC for developed net capacity.
EERU page using DNC to mean declared net capacity.
Some definitions and interesting discussions including wind vs nuke comparisons.

AHA.

Description of a wind turbine and a nuke, giving GWh/year for both.
