This is selected by the designer by taking careful account of all project constraints.<\/span><\/p>

Flow availability which has been determined by site survey and catchment study is the initial constraint. Typically, a value of Qmean (i.e. average annual flow ) or lower is used as the design flow rate. As a first estimate of site viability, Qmean can be used if an accurate historical value can be established. If no turbines are available because Qmean is too high, then reduce the value of the design flow rate in 10% steps until a suitable system is identified. Further factors affecting the design flow rate include:<\/span><\/p>

–\u00a0 <\/span>Environmental constraints (e.g. \u2018hands off\u2019 flow and\/or flow split requirements)<\/span><\/p>

A feed-in tariff is simply a guaranteed price set by the government for anyone who wants to sell renewable electricity to the grid, and a guarantee that they will have access to the grid to do so.<\/span><\/p>

The price, or tariff, is set so that a modest profit is ensured, thereby unleashing the collective capital resources of the entire province, state or country to be part of the transition to renewable energy.<\/span><\/p>

Feed-in tariffs exist in more than 20 countries. They are the most common policy for encouraging renewable energy systems, in part because \u201cfeed-in mechanisms achieve larger deployment at lower costs\u201d than other policy mechanisms such as quotas, direct incentives or voluntary goals.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

A graph showing the percentage of time that the flow at a particular river location equals or exceeds certain values. <\/span><\/p>

This is a method of characterising the flow variations at a particular site. A simple flow duration curve can be created by organizing all measured flow values in order of magnitude with the largest first. <\/span><\/p>

The more data which is used, the more likely that the resulting graph will be indicative of future flow patterns. The Y axis is used to show flow rate and the X axis is divided into 100 percentage points. This is used to illustrate the probability of a particular flow rate being equalled or exceeded (PE or Probability Exceedence). <\/span><\/p>

For example, the flow rate occurring at the 50 per cent mark (referred to as Q50) would be equalled or exceeded for 50 per cent of the time, therefore a period of six months of the year if flow data in complete years is used. <\/span><\/p>

Similar to flow duration curve, except expresses the change in head and the probability of a particular value being equalled or exceeded.

A head duration curve is important at some low head sites as the change in head levels will have a significant effect on energy capture. <\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The process of allowing electricity generated by a grid-interconnected renewable energy system to offset the electricity usage of the associated electric account at the same geographic location as the system.<\/span><\/p>

Net metering is an electricity policy for consumers who own (generally small) renewable energy facilities Under net metering, a system owner receives credit for at least a portion of the electricity they generate.<\/span><\/p>

Most electricity meters accurately record in both directions, allowing a no-cost method of effectively banking excess electricity production for future credit. However, the rules vary significantly by country and possibly state\/province: if net metering is available, if and how long you can keep your banked credits, and how much the credits are worth (retail\/wholesale).<\/span><\/p>

In the U.S.A., as part of the Energy Policy Act of 2005, under Sec. 1251, all public electric utilities are now required to make available upon request net metering to their customers.[3]:<\/span><\/p>
