Some content implies that new dams in Manitoba will deliver on Kyoto obligations by exporting energy. Manitoba Hydro is actively planning new hydroelectric dams and transmission lines. The licensing process for the first of a 'new generation' of hydro projects - the Wuskwatim Generating Station and Transmission projects began in November Federal approvals and provincial environment licences were issued summer
Choose your pipe type based on head, flow, run length, Hydro one full case final your budget. Intake and top section of penstock with standpipe vent.
Supporting the penstock with brackets and cables helps keep the run smooth and prevents pipe movement. A chunk of concrete, cast in place, acts as a thrust block for a small change in direction of this penstock.
The components at the bottom: Thrust block, coupler, pressure gauge, cleanout valve, nozzle valves, turbine, and tailrace.
Intermediate If you want to extract every last bit of energy from your microhydro system, three main components are critical to optimal performance—intakes, penstocks, and turbine selection.
Intake options were covered in HP, along with various methods of diverting water from the source. In many ways, the penstock pipeline is the most important part of your hydro-electric installation.
Trying to cut corners on this design element can cost you in performance. Common drainpipe is thin-walled and not rated for pressure. Though it can accommodate up to about 30 feet of head if you are careful opening and closing valves, drainpipe is not normally a recommended choice.
For example, with feet of head, the static pressure is about 87 pounds per square inch psi. Multiply that by 1.
To compute the static pressure for the proposed penstock in psidivide the total head in feet by 2. To save on penstock costs, a system can use pipes of increasingly higher pressure ratings as it gets closer to the bottom of the run, where pressure is highest.
In that case, calculate the pipe pressure ratings for different total heads as you move down the pipeline.
Some hydro installers will disagree, but my strong preference for penstocks is to use PVC pipe in foot lengths with a bell end for gluing lengths together.
Splices used for other pipe types are not reliable at high pressure or for unrestrained pipe movement. Thin-wall poly pipe comes in a long roll and can be easy to use, especially if your penstock has to weave through trees and over rocks to the turbine, and if you can complete the entire run without splices.
Thick-wall poly pipe requires special butt-welding equipment. The welds will leave a bead on the inside of the pipe that will affect flow. In our area, the critters tend to like chewing on poly pipe, but in other parts of the country, they seem to have a taste for the white PVC.
Aluminum pipe can be easy to get in agricultural areas but generally should only be used for pressures up to about psi. It should not be buried unless treated to deal with the acidity in soils. Steel will handle very high pressure but should also not be buried, since it will rust out over time. They are available at even higher pressure ratings but can be hard to get in larger sizes.
Dealing with Losses Aluminum, steel, and poly pipe have comparatively high friction loss resistance to flowso it is important to factor this loss into sizing—which can play a part in system cost. As with different types of electrical wire, every pipe type has different resistance to flow based on the roughness of the walls.
Also like wire, the diameter of the pipe determines the resistance to flow and how much flow the penstock can handle. In very high-head situations, steel pipe might be the only pipe capable of handling the high pressures.
Pipe friction-loss tables for each pipe material will tell you how much flow a particular pipe size can handle. Then, by comparing prices, you can determine if changing pipe diameter or material type is worthwhile.
Steel and aluminum pipes generally have double or more the resistance of PVC, and the larger sizes tend to make it prohibitively expensive for use in small systems.
Friction-loss tables are commonly used for hydro penstock sizing visit www. The following rules are for typical PVC schedule pipe with runs of to 1, feet.
Short, straight pipe runs can exceed these max flow rates a little—longer pipe runs need to be reduced. Up to 7 gpm can use 1-in. If you are pushing the envelope within a pipe size, it is usually better to go bigger.
This strategy will almost always improve system performance. The same holds true for long pipe runs. Bigger pipe will make more power available to your hydro plant at the bottom end of the penstock.
Penstock Protection Poly pipe is well known for being chewed on by rats, raccoons, and bear, to name just a few—but PVC has been attacked too. On the other hand, poly pipe can sometimes be better than harder-shelled pipe types because it is relatively freeze-tolerant and can be a little tougher for laying over treacherous terrain.Hydro power plants capture the energy released by water falling through a turbine and converts this into mechanical power, which drives generators to produce electricity.

Hydro One’s impending acquisition of Avista may work for shareholders, but it’s far from clear that the $billion deal is in the public interest, writes Jennifer Wells.
While the Orillia Power case had been delayed pending a final decision on Hydro One’s distribution rate application, the case was resumed at the start of this year, leading to the recent Decision and Order. 05/03/ Hydro One Case Study Hydro One Inc. is the largest electricity delivery company in Ontario, and price management with a final goal of total privatization.
