Yeah, he starts out negative and then goes off the deep end in the later pages which are just a personal rage against some specific politicians in Holland.
Having said that, the original pro-wind web site that they aped the name of (to annoy them) is equally opposite in painting a overly rosey picture with no reference to the downsides of wind power at this scale.
http://www.wind-energy-the-facts.org
It's very thin on answers. It acknowledges that upgrades to the grid infrastructure will be required to integrate wind power farms but doesn't say how.
It acknowledges that wind power is variable (but skims over just how variable) and then says that there's no problem with the variability affecting load scheduling because a) the variations are covered by primary generation response capability and b) that wind power accounts for an insignificant proportion of generating capacity.
This is all wrong. Control centres have prior knowledge of all large swings in load - even to the point of looking at the TV schedules to guess that when a 10 million viewer rated soap drama has it's half-way commercial break in the evening, 7 million viewers will go out and "put the kettle on". It's less of a problem these days as we have more channels and the days when 20m people routinely watched the most popular soap drama on one of the 3 TV stations have gone. Still, large industrial loads are required to call in before starting up.
The UK has the Dinorwig hydro power storage station of 1.7GW but this is for short notice load balancing only. It uses off-peak grid power to pump the water up the mountain to a reservoir so that later at steep gradient demand surges it can release that energy back to the grid when primary generation cannot ramp that quickly. Dinorwig can go from zero to 1.7GW in 16 seconds and can be spun up, synchronised and on-line with 1.3GW in 12 seconds. The problem is that it can deliver this for only 5 hours and takes 7 hours to recharge (pump all the water back up the hill, using 1.6GW of grid power).
The stated plan for Europe is to massively expand wind power (amongst other unreliable renewable sources) generation to 20% of demand. This negates their argument that wind power does not form a significant proportion of generating capacity so the variations are negligible.
If we really were to install 20% of UK demand in wind power, that would be just short of 8GW capacity (2,654 3MW turbines). Dinorwig is the largest hydro-storage project in Europe and is designed only to cope with short term
load variations. It is designed to allow planned starting and stopping of primary generating capacity in bulk. Dinorwig can quickly supply a few minutes of peak demand over the running primary capacity and then later either spare primary capacity can be used to recharge it or, if necessary, another chunk of primary capacity can be spun up to aid with recharging. The difference is that this generator can be started, run for 7 hours at full load and then stopped. Steam powered turbines (coal, gas, oil, nuclear) only run most efficiently when run at near full load.
Dinorwig can also cater for sudden catastrophic failure of a single power station (unplanned outages) but only long enough for an alternate power station to be spun up and take its place. It cannot cope with a variable load
and an unpredictable primary source. The swings in load gradient will be greatly magnified (worst case is a "coffee break" at the same time as a drop in the wind).
We're lucky though... Wales is a mountainous and persistently wet place. Holland is flat.
The wind generating proponents aren't considering the large scale picture. They install these 3MW generators all over the place and how you transport the power to where it's needed and how you iron out the irregularities in its delivery are "somebody else's problems".
Everyone who has run an off-grid system knows that you need backup generation for your wind turbine or solar array. Sharkey's and my solar systems are a backup to the grid. We use solar as much as possible but there are still times when we have to hook up the batteries to the grid charger to prevent the lead acid batteries rotting through over-discharge in winter or bad weather.
Solar and wind have a valuable place in offsetting use of primary generation but they cannot be counted on as reliable primary sources.
