(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Choma; this tower was commissioned on November 1, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Choma, Southern Province, Zambia on flat terrain, surrounded by sparse trees (greater than 10 ft / 3 m in height). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.

(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Malawi; this tower was commissioned on December 21, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Chipata, Eastern Province, Zambia on flat terrain, surrounded by sparse trees (up to 30 ft / 10 m in height). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.

(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Mansa; this tower was commissioned on November 26, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Mansa, Luapula Province, Zambia on flat terrain, surrounded by trees (up to 16 ft / 5 m in height) and sparse trees (up to 30 ft / 10 m in height). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.

(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Mpika; this tower was commissioned on November 20, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Mpika, Northern Province, Zambia on flat terrain, surrounded by trees (up to 30 ft / 10 m) and sparse trees (greater than 30 ft / 10 m in height). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.

(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Mwinilunga; this tower was commissioned on December 3, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Mwinilunga, North Western Province, Zambia on flat terrain, surrounded by trees (up to 30 ft / 10 m in height), and sparse trees (greater than 30 ft / 10 m in height, up to 80 ft / 25 m). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.

(hereafter “DNV GL”) to provide a validated mesoscale wind atlas for Zambia, including associated deliverables, and wind energy feasibility and development training courses. Validation of the wind atlas will be undertaken with data from eight (8) wind measurement meteorological towers installed throughout the country in 2016 by DNV GL. In this regard, the present commissioning report details all information associated with the installation of the meteorological tower, referred to herein as Mast Petauke; this tower was commissioned on December 9, 2016. A general description of the site is provided, along with the specifications of the instruments, tower and data acquisition system. 2 GENERAL DESCRIPTION OF TOWER LOCATION The tower was installed in the vicinity of Petauke, Eastern Province, Zambia on flat terrain, surrounded by sparse trees (up to than 30 ft / 10 m in height). The tower is obstacle free in its surroundings and a map representing the site is shown in Figure 2-1. Measured coordinates and elevation at the base of the tower during the commissioning of the mast are shown in Table 2-1.
