Overview
The Madurankuliya Wind Farm is an operational wind energy facility located in Narakkaliya, within the Puttalam District of Sri Lanka. This installation represents a significant component of the country's renewable energy infrastructure, specifically leveraging the wind resources of the Puttalam region. The facility is strategically situated bordering the Lakvijaya Power Station, integrating wind generation into the broader energy landscape of the area. As a dedicated wind farm, it contributes to the diversification of Sri Lanka's power generation mix, moving beyond traditional thermal sources.
The plant has a total installed capacity of 12 MW, which is generated by a specific configuration of turbine units. The operational structure consists of eight individual wind turbines, each with a rated capacity of 1.5 MW. These units are identified as ReGen VENSYS 82 models, a specific technology choice for this site. The technical specifications of these turbines include a hub height of 85 m and a rotor diameter of 82 m, designed to capture wind energy effectively at the site's specific altitude and spatial constraints. The turbines are rated for wind speeds of 13 m/s, although the site typically experiences average wind speeds of approximately 7.4 m/s, indicating the engineering parameters selected for optimal energy capture under local meteorological conditions.
Operational responsibility for the Madurankuliya Wind Farm lies with Daily Life Renewable Energy (Pvt) Ltd, which serves as the primary operator of the facility. This operating company functions as a subsidiary of WindForce (Pvt) Ltd, a major entity in the Sri Lankan wind energy sector that owns most of the existing wind farms in the country. This corporate structure highlights the consolidation of wind assets under the WindForce umbrella, with Daily Life Renewable Energy managing the day-to-day operations and technical maintenance of the Madurankuliya site. The facility has been in operation since its commissioning in 2012, marking over a decade of continuous energy production in the region.
History and Development
The Madurankuliya Wind Farm represents a significant addition to Sri Lanka’s renewable energy infrastructure, situated in Narakkaliya, Puttalam. Development of the project was driven by Daily Life Renewable Energy (Pvt) Ltd, which serves as the primary operator of the site. The ownership structure reflects the consolidated nature of Sri Lanka’s wind energy sector, where large holding companies manage multiple generation assets to optimize grid integration and operational efficiency.
The project was commissioned in 2012, marking the entry of this specific capacity into the national grid. The development involved the installation of eight ReGen VENSYS 82 wind turbines, each with a rated capacity of 1.5 MW, contributing to the total installed capacity of 12 MW. The technical specifications of the chosen turbines were tailored to the specific meteorological conditions of the Narakkaliya site. The turbines feature a hub height of 85 m and a rotor diameter of 82 m, designed to capture wind energy effectively in the local environment.
Site selection and turbine configuration were based on detailed wind resource assessments. The ReGen VENSYS 82 models have rated wind speeds of 13 m/s, which is notably higher than the average wind speed experienced at the site, recorded at approximately 7.4 m/s. This discrepancy highlights the engineering considerations required to maximize energy yield in locations where wind speeds may not consistently reach the turbine’s peak rating. Additionally, the wind farm operates under specific atmospheric conditions, with air densities measured at 1.158 kg/m³. These environmental factors directly influence the power output and operational performance of the wind farm, requiring careful monitoring and maintenance by the operator to ensure long-term reliability and efficiency in the Puttalam region.
Technical Specifications
The Madurankuliya Wind Farm is equipped with eight ReGen VENSYS 82 wind turbines, each with a rated capacity of 1.5 MW. This configuration results in a total installed capacity of 12 MW. The facility is operated by Daily Life Renewable Energy (Pvt) Ltd, a subsidiary of WindForce (Pvt) Ltd, which owns most of the existing wind farms in Sri Lanka.Turbine Specifications
The ReGen VENSYS 82 turbines feature a hub height of 85 m (279 ft) and a rotor diameter of 82 m (269 ft). These turbines have rated wind speeds of 13 m/s (43 ft/s). The site experiences average wind speeds of about 7.4 m/s (24 ft/s), which is lower than the rated wind speed of the turbines. The wind farm also experiences air densities of 1.158 kg/m3 (0.072 lb/cu ft).| Parameter | Value |

| Number of Turbines | 8 |
| Capacity per Turbine | 1.5 MW |
| Total Capacity | 12 MW |
| Hub Height | 85 m (279 ft) |
| Rotor Diameter | 82 m (269 ft) |
| Rated Wind Speed | 13 m/s (43 ft/s) |
| Site Average Wind Speed | 7.4 m/s (24 ft/s) |

Site Characteristics and Meteorology
The meteorological profile of the Madurankuliya Wind Farm presents a distinct engineering challenge, characterized by a notable disparity between the rated wind speeds of the installed turbines and the actual average wind speeds experienced at the site. According to technical specifications for the facility, the site experiences average wind speeds of approximately 7.4 m/s (24 ft/s). This figure is significantly lower than the rated wind speed of the individual turbine units, which is specified as 13 m/s (43 ft/s). This mismatch suggests that the turbines operate below their full rated capacity for a substantial portion of the time, a common characteristic in wind energy projects where the cost of turbine capital expenditure is balanced against the probability distribution of wind velocities.
The air density at the Madurankuliya site is recorded at 1.158 kg/m³ (0.072 lb/cu ft). Air density is a critical variable in wind energy production, as it directly influences the power output of a turbine for a given wind speed. The standard air density often used in general wind energy calculations is approximately 1.225 kg/m³ (at sea level and 15 °C). The slightly lower density at Madurankuliya, likely due to the tropical climate and elevation of the site in Puttalam, means that the air mass passing through the rotor disc exerts slightly less force than in standard conditions, further affecting the energy yield per cubic meter of air. This specific density value is a key parameter in the performance modeling of the eight ReGen VENSYS 82 turbines that comprise the farm.
Turbine Specifications and Site Integration
These turbines feature a hub height of 85 m (279 ft) and a rotor diameter of 82 m (269 ft). The selection of a hub height of 85 m is a strategic decision to capture higher and more consistent wind speeds above the ground-level turbulence. The rotor diameter of 82 m provides a swept area that allows for efficient energy capture at the prevailing wind speeds of 7.4 m/s. The fact that the rated wind speed (13 m/s) is nearly double the average wind speed indicates that the turbines are sized to handle peak wind events and maximize energy capture across a broad range of wind velocities, rather than operating at peak efficiency only during average conditions.
The location of the wind farm in Narakkaliya, bordering the Lakvijaya Power Station, may also influence the local wind patterns. The proximity to a thermal power station can introduce thermal plumes and local turbulence, which can affect the wind shear and turbulence intensity experienced by the turbines. However, the specific impact of the Lakvijaya Power Station on the wind resource at Madurankuliya is not detailed in the available technical data. The operational status of the wind farm, which has been operational since its commissioning in 2012, suggests that the site characteristics, including the wind speed and air density profiles, are suitable for sustained energy production under the management of Daily Life Renewable Energy (Pvt) Ltd.
