Feasibility Study: Powering Manzanilla with a Wind Farm
A feasibility study by Mickhal Polisher and team from The University of Trinidad and Tobago explores the potential of powering the area of Manzanilla with a wind farm. The study aims to determine the power consumption of the area, assess the use of wind resources to meet demand, and evaluate the viability of installing a wind farm. Detailed analyses include information on the area, number of structures, power consumption estimates, and wind data collected.

Feasibility of Powering Manzanilla via a Wind Farm Mickhal Polisher, Edward Cumberbatch, Aneil Ramkhalawan, Jorrel Bisnath, Aatma Maharajh Design and Manufacturing Systems, The University of Trinidad and Tobago, Trinidad and Tobago IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
OBJECTIVES To determine the average power consumption of the area of Manzanilla that is under focus. To determine if the resource of wind in the area can be used to meet the demand of Manzanilla. To determine the viability of installing a wind farm in Manzanilla. IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
AREA UNDER STUDY Manzanilla - Inclusive of North Manzanilla Road and The eastern main road from the Manzanilla gas station to the coastline IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
NUMBER OF STRUCTURES Type Eastern Main Road, Manzanilla 156 North Manzanilla Road, Manzanilla Total Residences 79 235 Businesses 29 8 37 Combinations 16 9 25 Totals 201 96 297 IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
POWER CONSUMPTION Initially estimated to be between 8910 kWh and 9900 kWh based upon total occupancy and electric consumption based on survey. Information from the TTEC places the actual value at 1 MVA Measured from 6am to 6pm. Power Factor for system given as 0.8. Apparent power consumption of area is 1 MVA Conversion to Real Power uses Power factor Real power consumption is 800 kW over 12-hour period IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
WIND DATA From research: Minimum wind speed required for turbine spin is 4.97 mph Minimum to begin power generation is 7.82 mph Combination of data gathered from multiple sources Windfinder.com Shows Snapshot data Weatherspark.com Has wind data measured over a year IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago

WIND DATA Wind Data Data from Weatherspark.com Darkest line shows average hourly wind speed per month IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
WIND DATA FROM THE UK Data here shows a max of 11.7 knots and a min of 7.1 knots. Converts to a peak of 12.7 mph and a low of 8.17 mph. UK houses the London Array which is one of the biggest offshore wind farms in the world producing 630 MW IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
TURBINES Two types: Horizontal Axis Vertical Axis Each has their own Advantages and Disadvantages. IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
HAWT VS VAWT Horizontal Axis Requires a fixed direction or adjusting apparatus Best used in high altitude Lower drag due to blades turning with the wind Vertical Axis Non-directional Lower noise level Less efficient due to drag Can use less surface area IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
COSTS The Endurance E-3120 Low end turbine Capacity of approximately 55 kW Listed as 250,000.00 per unit on many marketplaces Using given power consumption 16 units required for power consumption rates Total cost for turbines only 4,000,000.00 IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
SITE SELECTION In selecting space for farm installation there are options to consider Offshore More expensive Higher overall wind speed Land based Lower operating costs Wind less likely to be constant Environmental Impact IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
ENVIRONMENT OF MANZANILLA Forested area teeming with wildlife Red Howler Monkey Protected under the Conservation of Wildlife Act Applications for ESS status filed recently IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
OFFSHORE DRAWBACKS Manzanilla has many migratory birds in its environment Installation has a chance of disrupting their patterns or even causing injury. Additionally, dependent on the height of the installation, flights out to offshore platforms would need to be diverted IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
CONCLUSIONS Wind speeds comparable to other countries with wind farms Costs could be too high for small community Environmental impact on wildlife could be high IConETech-2020, Faculty of Engineering, The UWI, St. Augustine, Trinidad and Tobago
