Fig 3. Probability that the rated power of one, two, three or the entire plant can be achieved in any given month. Equivalent to the probablity that the Load rejection at unit full load (at rated power) test can be perfomred with the avilable head. Based on modelling from 93 years of historic data.

` }35:T463,html ` Fig 3. Shows the probability that rater power can be achived for one, two and three units and the full plant (four units) in each month. It is assumed that the required flow can be provided by storing water in the headpond (as for the rated flow tests above) so the limiting factor for these tests becomes the available head. Headlosses in the power canal are proportional to the flow in the canal so avilable head and the probability of performing the tests falls slightly for 2 or more untis.

It is important to note that in any particular year the probability of being able to perform the tests in a given month is not independent of the probability in the previous months. For example in a particular year if there is insufficient head to undertake tests in January then the tests will also be impossible in February and March and will not be possible again until the rate of flow drops sufficiently to provide the additional head necassary for the tests. This may not be until June or July. In the worst case therefore it may be necassary to wait up to six months to be able to undertake these tests. `36:T51d,{ function box(prop,name, div_name,col){ var data1 = [{ y: yearly.map(m=>366-m[prop]), type: 'box', marker: {color: col}, name:name, boxmean: true}] var layout1 = { height: 300,width:width/4, margin: { l: 70, r: 10,b: 30, t: 30 }, font: font, yaxis: {title: 'Days', zeroline: false,showline: false,range:[0,200],tickformat: ',.0f'} }; const div1 = DOM.element(div_name); plt.newPlot(div1, data1, layout1,{displayModeBar: false}); return div1 } return html`
