Ministry to build micro-hydro power plant in Hukurila, Maluku
Guntar Maha, an official of the Maluku River Center for Raw Water Commitment, said the micro-hydro power plant would be a pilot project using renewable energy, namely the watershed of Way Rupa.
The project would be built in Hukurilla village because the village was close to the Way Rupa river which had potential discharge and height differences that would be turned into micro-hydro energy sources, he said.According to Guntar, the construction of the micro-hydro power plant project required the clearing of land and procurement of such things as turbines, concrete wire, tranquilizer tank, pillars for supporting concrete pipes, house plants and channel release.The hydro project would be located 20 kilometers from Ambon city and be inaugurated by Public Works Minister Djoko Kirmanto who also would attend the 18th Annual Scientific Meeting (PIT) of the Indonesian Hydraulic Engineers Association (HATHI) on October 28 to 30, 2011, Guntar said.The hydro project would also include the building of a one-kilometer-long transmission network from the waterfall`s location to Hukurilla beach which had a population of 147 households or 623 people.Thus the hydro project would also support the development of maritime tourism in Hukurilla which has a beach with coral panorama, underwater caves and various types of reef fish that make it an ideal dive site for domestic and foreign tourists, he added.“We will involve staff from the Public Works Research and Development Agncy in Bandung to build the micro-hydro power plant Hukurilla.
Similar hydro plants would be developed in other areas in Maluku which have waterfalls with water flows and high difference potential,” said Guntar.
The goal was to reach areas that do not have electricity from State-owned ElectricityCompany (PT PLN) of Maluku and North Maluku region.Micro hydro power plants use the potentials of waterfalls to generate electricity.
The objective was to provide environmentally friendly electric power at low operating and maintenance costs in order to improve the quality of life and fostering the economic growth of the rural communities, Guntar said.Editor: Suryanto

Whenever a conductor moves relative to magnetic field, voltage is induced in the conductor.
Note that the load current in turn creates a magnetic field that opposes the change in the flux of the coil, so the coil opposes the motion.
The higher current, the larger force must be applied to the armature to keep it from slowing down.
In the animation the coil is rotated by the hand crank. In practice, the mechanical energy is produced by turbines or engines called prime movers.

Ambon, Maluku (ANTARA News) – The ministry of public works will build a micro hydro power plant in Hukurilla village, South Leitimur sub district, Ambon city, Maluku province with a capacity of 3.30 KiloWatt, a local official said here Tuesday.
Guntar Maha, an official of the Maluku River Center for Raw Water Commitment, said the micro-hydro power plant would be a pilot project using renewable energy, namely the watershed of Way Rupa.
The project would be built in Hukurilla village because the village was close to the Way Rupa river which had potential discharge and height differences that would be turned into micro-hydro energy sources, he said.
According to Guntar, the construction of the micro-hydro power plant project required the clearing of land and procurement of such things as turbines, concrete wire, tranquilizer tank, pillars for supporting concrete pipes, house plants and channel release.
The hydro project would be located 20 kilometers from Ambon city and be inaugurated by Public Works Minister Djoko Kirmanto who also would attend the 18th Annual Scientific Meeting (PIT) of the Indonesian Hydraulic Engineers Association (HATHI) on October 28 to 30, 2011, Guntar said.

Mini-hydro scheme generate electricity for National Grid
Scottish Water has converted an old treatment works into a mini-hydro scheme, which is producing renewable energy for the national Grid.
Touch water treatment works has been installed with a 52kw turbine in a scheme with the potential to generate 300MWh a year or the equivalent of 50 homes worth of power.
Several water treatment sites across Scotland, which had been producing drinking water for 100 years, were put out of service last year.
More than 200 of these could be used to produce renewable energy in a similar way to Touch water treatment works.
Scotland contributes 85% of the UK’s hydro energy and is leading the way in many areas of renewable energy technology.
Richard Allan, Scottish Water Horizons Managing Director, said: “We are making best use of Scottish Water assets to contribute to a greener Scotland. While each site generates only a modest amount of power they all add up.”

Operation of electric generators is based on emf electromotive force
Whenever a conductor moves relative to magnetic field, voltage is induced in the conductor.
Particularly, if a coil is spinning in a magnetic field, then the two sides of the coil move in opposite directions, and the voltages induced in each side add.
Numerically the instantaneous value of the resulting voltage (called electromotive force, emf)
is equal to the minus of the rate of change of magnetic flux Φ times the number of turns in the coil: V=−N•∆Φ/Δt. This relationship has been found experimentally and is referred to as Faraday’s law. The minus sign here is due to Lenz law, which states that the direction of the emf is such that the magnetic field from the induced current opposes the change in the flux which produces this emf. Lenz law is connected to the conservation of energy.
For clarity in the above animation a single rectangular conductor loop is shown instead of an armature with a set of windings on an iron core.
Since the rate of magnetic flux change through the coil that spins at a constant rate changes sinusoidally with the rotation, the voltage generated at the coil terminals is also sinusoidal (AC).
If an external circuit is connected to the coil’s terminals, this voltage will create current through this circuit, resulting in energy being delivered to the load.

Hydro Electric to Power Global Renewable Energy Generation
Hydro Electric to Power Global Renewable Energy Generation
Hydro electricity will be at the forefront of renewable technologies, leading the global green energy growth.
According to a new report, over the next quarter of a century, hydro power will account for 55% of all renewable energy added worldwide.
The ‘International Energy Outlook 2011′ predicts that between 2008 and 2035, globalelectrical renewable energy generation would grow an average of 3.1%pa, withelectricity generation from renewables increasing from 19% in 2008 to 23% in 2030.
Key elements of the reported pointed to:
4.6 trillion kilowatt-hours of new renewable generation will be added over the projection period.
Of that, 55% – 2.5 trillion kilowatt-hours – will be achieved by hydro power.
Aside from hydro, the majority of renewable technologies are not able to compete economically with fossil fuels during the projection period, except in a few regions or niche markets.
The primary economic motivation for the uptake of renewables is down to Government incentives and policies.
The greatest increase in hydro electric growth was outside the developed countries of the Organisation for Economic Cooperation and Development (OECD). This is largely due to hydro electric plant projects in areas such as Brazil, India and China.
The generation of hydro power globally would increase from 3.1 trillion kWh in 2008 to 5.6 trillion kWh by 2035.

First Archimedes screw turbine on River Thames
Mapledurham Estate creates electricity with new Archimedes screw turbine
The owners of an Oxfordshire watermill have unveiled a water turbine which could provide power for homes.
The £500,000 Archimedes screw project is funded by the Mapledurham Estate, owned by the Blount family since 1492.
The estate includes a Grade I listed Elizabethan manor house and the last commercial working watermill on the River Thames.
From this Sunday, visitors to the house will be able to view the giant turbine by walking over a footbridge.
The new Archimedes screw will replace an old turbine which is located in the river bed on one side of the 15th century watermill.
‘Big screw’
The previous turbine was installed in the 1920s and supplied the manor house with electricity for many years, but is no longer working.
Corry Starling, water bailiff at Mapledurham Estate, said the new turbine would pay for itself in 10 years, and would generate income for the estate’s upkeep.
He said: “It’s a huge great big screw, known as an Archimedes screw.
“Our turbine will have the most water going through it of any Archimedes screw in the country.
The turbine is expected to generate 500,000 kW hours per annum.
It will be powered by 1,800 gallons (8,000 litres) of water per second, the equivalent of 280 Olympic sized swimming pools every day, according to Mr Starling.
The hydro electricity project has taken two years from planning application to completion.
The Mapledurham estate’s watermill will continue to produce flour for sale.
The mill was used as a location in the film The Eagle Has Landed and also featured on the cover of the eponymous 1970 debut album of the heavy metal band Black Sabbath.

Marks and Spencer funds huge Archimedes Screw at Mapledurham Estate to supply power for its stores
The UK’s biggest Archimedes Screw will be unveiled today at the site of the last working watermill on the River Thames.
The £500,000 hydroelectric turbine has been fitted at the Mapledurham Estate in Oxfordshire, replacing a defunct turbine that was installed on the side of the 15th century watermill in the 1920s to generate electricity.
Around 8,000 litres, the equivalent of 280 Olympic-size swimming pools of water, will cascade through the 24.7 tonne turbine each day. Over the course of a year, the screw will produce approximately 500,000kWh of renewable electricity for retailer and financial backer Marks and Spencer, sufficient to power one of itsstores.
The turbine is expected to pay for itself within 10 years and generate income for the estate, which also produces milk for Marks and Spencer and flour for sale.
“It’s been our long-standing ambition to generate renewable electricity from the last working watermill on the Thames,” John Eyston, owner of the estate, told the Guardian. “We’re delighted the hydropowered turbine is now up and running, providing a sustainable additional income for the future from this historic site.”
After successfully negotiating a two-year planning application, the Mapledurham screw has beaten a number of other proposed projects to completion, including two 40-tonne Archimedes Screws that were recently installed for the Queen at Romney Weir, near Windsor Castle.
To pass strict environmental requirements the 3.5 metre screw has been designed to allow fish to swim safely through the machinery. It should also be resistant to flooding or debris.
Visitors to the estate can see the hydroelectric system for themselves, alongside the Grade I-listed Elizabethan manor house and the historic mill, which was used in the film The Eagle Has Landed and featured on the cover of Black Sabbath’s 1970 eponymous debut album.

A “mini-hydro” power scheme using old waterworks in Scotland has started generating renewable energy in the hills west of Stirling.
Scottish Water began exploring the possibility of using Touch water treatment works for hydro power at the end of its working life.
It has now started generating for the National Grid following the installation of a 52kw turbine.
It aims to capture energy from water flowing down from hilltop reservoirs.
The scheme, run by Scottish Water’s commercial and renewable energy business Horizons, has seen £400,000 invested.
It is hoped it will generate 300 MWh a year – enough to power 50 homes, and provide a return on the investment within 6 years.
‘First of many’
Richard Allan, Scottish Water Horizons managing director, said: “It’s great to see the Touch turbine going live as it’s the first of hopefully many similar schemes.
“We are making best use of Scottish Water assets to contribute to a greener Scotland. While each site generates only a modest amount of power they all add up.”
Horizons said it had analysed more than 200 Scottish Water sites and a number of these could be developed like Touch.
The reservoirs at Touch were created about 100 years ago.
They stopped being used for drinking water last year when Stirling was connected to the supply from Loch Turret treatment works in Perthshire, which also contains a hydro turbine.
Before the Touch turbine could start generating, a power export meter had to be installed and a licence was sought from Sepa (Scottish Environment Protection Agency). Advice was also taken from Stirling planners and the local landowner.

Mapledurham Estate on the banks of the Thames in Oxfordshire is now home to the biggest Archimedes screw in the UK – an update of millennia-old technology that will allow electricity to be generated from 280 Olympic swmming pools of river water washing through the turbine every day.
Several other hydropower plants have been proposed for the Thames, including one for the Queen at Windsor, but none are yet operational.
The 900-year-old estate – whose watermill was mentioned in the Domesday Book – supplies milk to Marks & Spencer, which has helped to finance the renewable energy project, providing the retailer with about 500,000kWh of renewable electricity each year, or enough to power one of its average stores.
John Eyston, owner of the estate, said the deployment of the hydropower technology was a long-held dream. He said: “It’s been our long-standing ambition to generate renewable electricity from the last working watermill on the Thames. We’re delighted that the hydropowered turbine is now up and running, providing a sustainable additional income for the future from this historic site.”
Converting old watermills to produce electricity can be tricky, in part because of the need to gain planning permission and to build in protection for fish. At Mapledurham, the system has been designed so that fish can swim safely through the machinery, which is 3.5m in diameter, and it should not break down if hit by flooding or debris. Work on the turbine was begun in April and finished within six months.
Under its “plan A” project to be more environmentally sustainable, M&S is encouraging small suppliers, including farmers, to build renewableenergy generation by guaranteeing to buy the electricity under a five year fixed price contract. This steady income stream helps the supplier to raise the finance needed for the upfront cost, and many of the schemes are also eligible for government subsidies under the renewable obligation or feed-in tariff schemes.
The watermill at Mapledurham Estate, which has been a favourite subject of British artists down the years, will be open to viewing by the public at certain times.
