Hola,

This is a funny looking turbine based on the Savonius style. It should
produce lots of torgue, good for water pumping only. A lot of similar
designs appeared on the internet but with little success...
Georgios.

According to an article i've read in thenewspapers it produces more energy than a conventional one

Greetings

Here is some info on the Swift Turbine you refered to.
Some pictures available on their website.
I will try to get some idea of pricing next week.

http://www.renewabledevices.com/swift/index.htm

Universal rooftop Wind Energy System.
Embedded renewable electrical energy
Renewable heating system which augments existing hot water system
20 year product life with low maintenance
Rated power output: 1.5 kW
Annual Power Supplied: 4200 kWh
Design enables use of turbine in turbulent air flows
Silent mast mounting technology eliminates unwanted vibration to building


Cheers, Geert

I can not figure how to work this forum. Georgio, I am developing a project in the mountains of constanza. Screw eden norte. I have purchased 700 tareas and want to develop my own system of wind/diesel power. I want to build cabins and sell lots for others to build and sell power. I want to produce it all off grid. I would like to plan a system of adding about 8 cabins a year. I have a masterplan of 77 lots. I do not want to by something huge now but maybe later. Help me with a growth plan of power. Any thoughts?

Interesting article in Listin Diario today on wing power generation;

http://www.listindiario.com.do/cuerpos/dinero/din1.htm

It is interesting to note that all the studies have been done, areas have been laid out and the only thing holding things up, for a number of years, is the passage of the necessary bills through the government. It is also interesting to note that the Energy Law (125-01) states that no more than 20% of the electricity produced can be wind generated.

Another law set up to line the pockets of the already rich at the expense of the Dominicans and the Dominican Republic. At the expense of cleaner air and cheaper electricity do you envision changes being made?

Interesting observations on eolic energy. See http://grupomillenium.blogspot.com/

The author can be contacted by writing to Jose Antonio Vanderhorst at vanderhorstsr@gmail.com

He wants to see eolic energy a possibility for others than the big big companies that would install large parks.

DR has large wind-power potential
Apparently large-scale wind generation is just around the corner. Research has indicated that there is a vast potential of this "free" energy in three percent of the Dominican Republic. The potential generation is estimated at 10,000 megawatts, five times the present local demand. The BHD Group and the Spanish consortium GAMESA are promoting the Guanillo Energy Park, which is said to be able to contribute 90 megawatts of power to the national network. The project is supposed to use 129 wind turbines.
In the Superintendent of Electricity's office there are permit requests for projects that total 700 megawatts of energy. Ironically, however, the General Electricity Law (125-01) only allows for 20% of the nation's energy to come from wind generation. Currently at least five companies have received provisional concessions from the SIE. Ortega Zeller has a permit to study the area around Imbert, Puerto Plata; Elite Decor to study the winds around Lake Enriquillo, Barahona; International Eolic Generation will look at La Isabela in Puerto Plata; Poseidon Renewable Energy will study Puerto Plata and the BHD-Gamesa group will study Guanillo in Monte Cristi province.
This last group is currently the most advanced in its development. They have created the Eolic Park of the Caribbean (PECASA) with an initial investment of US$15 million. Of this sum, 29% belongs to the BHD Group, 57% belongs to the Gamesa consortium and the remaining 14 % to private Dominican investors. The first step of the project is expected to cost US$40 million. Approval from the Ministry of the Environment, the Civil Aviation Department and the Military Map Service have been received and the Superintendent of Electricity has approved the plans for the connection to the high tension line that runs from Navarrete to Monte Cristi by means of a 12 kilometer transmission line.
However, the largest hurdle that the project faces is the lack of legislation that promotes the development of alternate, renewable energy sources. The debate on the incentives needed to spearhead this type of energy has been in the Congress for six years. The director of the National Energy Commission's Alternate Energy department, Doroteo Rodriguez told Listin Diario reporters that the legislation has "many enemies", principally the current power generators, since eolic generation is more than 25% cheaper that current costs for fossil fuel generation.

Please contact me with javs@ieee.org instead, which is my permanent email address.

I am the organic seed of Grupo Millennium Hispaniola, which pretends to promote Dominicana and Haiti to become developed countries in this millennia. Most of the emphasis in the blog is on reliable electricity, which is the research that I am working on for quite some time. I firmly believe it is possible by differentiating electric service.

Demand Response and Energy Efficiency technologies with retail liberalization will eventually lead to replacing the regulator and the distributor as intermediaries. Customers in Dominican Republic can freely purchase individual solutions to supply security. By letting everyone by himself the country has created enourmous ineficiencies. I believe that the grid can serve "backwards" to integrate renewable energy investments. My latest presentation in Atlanta, Georgia, "Dominican Republic Electricity Risk: A Customer Orientation", can be download from the GMH blog.

Dolores has sugessted you to look at the three part "Small Is Beautiful" comments, in which I advocate for distributed wind development, instead of centralized solutions. Centralized solutions are second wave thinking; distributed resources are essential in the third wave, where electricity can be differentiated to enhance local reliability needs.

Last night I picked up some of the information of the Forum and placed it on the blog. I liked the comment on 100% reliable. That is part of my research findings. By thinking 99% and 100% we miss the essence of differentiation. Instead we should look a 0% and 1%. By doing so, we see that some customers want 2%, 1%, 0.5%, 0.1%, 0.05%, 0.01% or whichever one requires and is willing to pay for. Businesses with high interruption costs should pay for the kind of reliability that they want. Then, poor customers that have other priorities might be able to afford 3% reliability.

Anyone which feels can contribute to the aims of GMH is invited to become a member of GMH. Please email me to sent you an invitation.

The area has a wind class 4, which is a "good" wind sourse.
A very important factor is inspecting your "wind site". Visit:

www.windpower.dk/core.htm

click turbine sitting. Read all pages. This editorial will help you to decide
if a wind turbine is SUITABLE for your location.

Using multiple smaller turbines results in:
1. More wear & tear
2. More towers
3. More wires, transfer switches & misc connections.
4. More noise. Small rotors spin faster=increased fluttering!
5. Higher cost for overall kw production.
6. Aesthetically, your home will look like...well you know.
For small turbines "bergey" is the best. I located a few authorized
distributors in Santiago, DR. Go to www.bergey.com, click world distribution
and zoom into DR.
I suggest buying only the turbine. Given your elevation at 700 feet,
you can install a pivoting tubular metal tower approx 30 feet high. This tower
can be custom made locally having the "hinged" point 10 feet above
ground. Fix a counter weight at the bottom for easier erection. The reasons for this type of tower are:
1. Protect the turbine from hurricanes.
2. Easier inspection of components, lubrication and general maintenance.
3. Bring turbine to the ground when travelling abroad.
4. Replace rusting support wires.

My turbine design is based on large blades with slow rotation but high
torque. This design is less noisy, gives longer bearing life, is hurricane
proof and produces power even under a light breeze. Permanent magnet
generator is used with special design for low inertia-high efficiency.

Due to patent procedure, more info is not yet available, sorry.
Basically, three(3) models are tested:
a. 1kw for battery charging.
b. 10kw for stand alone.
c. 100kw for resorts.

Investing in windpower can be confusing and costly. Look at all products
out there before deciding how to go about it...Georgios.

Hi Richard, and Georgios,

You are both right. It all depends on what reliability the customer needs, what he is willing to pay, and what solutions are available. From my previous 99% - 100% comment, it should be obvious that some customers are happy with 1% reliability shortage. Those that require better reliability than is available from what existing solutions can offer, have to use redundancy to have smaller reliability shortages. That is why off system capacity becomes expensive. Power industry interconnection is the solution.

That is why the vertically integrated power industry was the most important technology of the 20th century. Deregulation of wholesale markets without deregulation of retail markets has been found to be the flaw the electric power industry is facing. The result: an unstable business system that is unable to resist shocks. Demand Response is the key to a robust and efficient solution, which was not possible in the second wave. As transactions costs become insignificant in the third wave, the vertically integrated power industry becomes inefficient, with respect to a fully functioning deregulated electricity market.
