Wind Energy in Rural Peru: a volunteer experience with WindAid


A great wind is blowing, and that gives you either imagination or a headache. - Catherine the Great 












It was a dark and rainy afternoon in February when I left Yorkshire in the North of England and set off for London to catch a flight southwards. My destination was Trujillo on the North West coast of Peru where I was to spend the next five weeks working as a volunteer with an organisation called WindAid.

Clean Energy
WindAid is an environmental development organisation that brings electricity to isolated communities in Peru through the manufacture and installation of wind turbines. Many rural communities in Peru have no access to electricity for basic needs such as education and healthcare. 

Others have a limited and costly supply through diesel generators which pollute the environment. Using simple technology, local labour and materials and a passion for sustainable energy, WindAid, along with an army of volunteers, are working to electrify isolated communities in Peru and provide access to the modern facilities we take for granted.


Arrival
After three flights and around 24hrs of travelling, I finally touched down, or rather bumped down, in Trujillo. As I left the aircraft, I was hit by a very pleasant blast of hot dessert air, a reminder that I’d left the cold English winter well behind me. I made my way out of the tiny airport and with some relief spotted the WindAid representative ready and waiting to greet me outside.
As we sped towards the city in Snr. Abel’s taxi I immediately felt welcome. Despite the fact that neither of us could speak each other’s language, Snr. Abel’s humour was infectious and communication was somehow easy. Over the next few weeks I would become very familiar with this warm Peruvian welcome.

A few hours later I met Michael Verkamp, the WindAid founder who wasted no time in showing me the local area including the beautiful resort town of Huanchaco and introducing me to Peruvian delicacies of roasted goat, Taco Taco (a very tasty rice dish) and of course Picso sour (the famous Peruvian spirit). It wasn’t long before I felt like one of the family.

The Work Begins
After a weekend to acclimatise, it was time for me and fellow volunteer John to start the real work. Monday morning began at 8.00am with a meeting of the WindAid staff held in Spanish – nothing like complete immersion to improve one’s language skills! It was a busy first day with a quick introduction to the workshop followed by a trip to one of the local WindAid turbines to replace the turbine blades.

I was immediately impressed with the ingenuity and efficiency of the WindAid team. Using limited resources and working into the dark we were able to dismantle the 9m high turbine, replace the blades and have it back up and generating again within a few hours. My first taste of Peruvian engineering.

During my time at WindAid, I had the opportunity to work at a variety of different sites and to participate in a wide range of tasks including manufacture, installation and repair. As a PhD researcher in wind energy, this exposure to a variety of installations and aspects of the wind energy system was an invaluable experience.

On the Road
By the second day we were already on the road travelling south through the spectacular desert coast of Peru, on our way to our first turbine installation. After arriving onsite we worked a full day and continued by torchlight after dark to complete our first installation. The next day we returned to complete the electronics. It was a great feeling to watch the blades spinning and see the only lights for miles around flicker into life powered only by the wind.

During the remainder of the week we visited a number of installations to make maintenance checks stopping occasionally for the freshest Ceviche or fried fish from the many beachside vendors along the Pacific coast. It was a great learning experience to see how the resourcefulness of the team was able to overcome the many engineering challenges faced in a developing country.

Solo en Peru
A particularly memorable incident occurred in small seaside town called Baranca. Realising the wind resource at one of the installations was better than previously thought; we needed to make a dump resistor to prevent the extra power from overloading the system. After several hours searching the small local town for supplies, we returned with two ceramic tiles, an electronic cooking element and a metal tray.

The next challenge was to find somewhere with electricity so we could drill the mounting holes needed to make the resistor. Finally we discovered a road-side repair shop with a small generator and after an hour or so of work on the pavement we had a fully functioning dump-load resistor. During my time in Peru there were many similar incidents, so much so that we coined the phrase ‘solo en Peru’ (only in Peru) in honour of the Peruvians’ ability to improvise and make the best of the limited resources available.

Making Turbines
Much of the following two weeks were spent in the workshop learning how to make the turbine components. The most complex process involves the blade manufacture where through a number of refinements, WindAid have developed an extremely strong and lightweight aerofoil. The manufacturing process is painstaking but very rewarding.

The components of the generator system are all hand-made right down to the winding of the coils for the stator. Being involved in these processes was a very valuable insight into the functioning of a wind turbine system. My time at the workshop was made particular pleasurable by the careful engineering explanations given by Fernando as well as the cheerful banter and expert guidance from Gean and Snr Abel.

During down-time there was the opportunity to explore some of the archaeological sites of Trujillo including the fascinating Pyramids built by the ancient Moche people as well as some of the more contemporary night-time attractions!

Into the Mountains
The final part of my placement with WindAid was perhaps the most rewarding. Early one morning we set off into the mountains along a winding road which quickly became a dirt track. The road climbed slowly to 4000m through spectacular scenery, before dropping down into the mountain village of Huamachuco. Our destination was Escuela Democratica, the site of a recent Volunteer WindAid installation.

As soon as I stepped out of the truck I could feel the effects of the altitude, a few steps felt more like a sprint. The effects of the altitude were soon forgotten however, this was picture postcard Peru! A place where women dressed in colourful layered dresses and wide brimmed hats and men ploughed fields with oxen, all against the amazing backdrop of the Andean mountains.

We were visiting the school to install the electronic system for the wind turbine inside the newly-built school building. By this time, I had learned enough to make a real contribution to the installation. It was very rewarding to know that our work there would help to improve the education and opportunities of the local children.

Into the Wild
The following day we paid a scoping visit to what we hope will be one of the next WindAid volunteer projects. A further 1.5 hours drive along dirt tracks into the mountains lays the small pueblo of Aceituna.

The drive is spectacular passing through huge swaths of eucalyptus trees which fill the air with their aroma. Along the route we passed local people driving herds of sheep or cattle, carrying huge bunches of corn or driving donkeys loaded with freshly cut wood. This is a place where everyone is busy but busy at a slow pace, walking for miles to move their cattle or to visit the local village.
After crossing a river we finally reached Aceituna. The small community that live there were extremely welcoming insisting we take bagfuls of fruit from their orchards. A video of an operating WindAid turbine proved to be star attraction. Many of the residents crowded around the tiny mobile phone screen to watch it spinning.

A turbine installation here could make a real difference. The proposed site is at the top of a hill at the location of a small health post which serves the village. It is the only healthcare available for miles around and when the river is in full flow the community is effectively stranded. Without electricity, even medicines cannot be kept cool and many basic medical procedures are not possible. After a site assessment we reluctantly leave the community, many of whom have gathered to wave us goodbye.

As we return to Trujillo I am humbled to see how much it means to these communities to simply have access to electricity, something that we take for granted every day. Despite having very little, these communities work hard to survive with dignity, displaying a real sense of gratitude for the help that’s offered them.

Farewell
All too quickly my time with WindAid has passed but it’s been an unforgettable experience. Not only for the practical skills I have gained but for the awareness of the social impact that schemes such as this can have and for the amazing people I have met along the way.

I would encourage anyone who is considering volunteering with WindAid to take the plunge. Not only will you help more people benefit from access to clean, renewable energy, you will also have an unforgettable experience along the way!
