NECESSITY OF WIND POWER DEVELOPMENT IN VIET NAM (1)
● Using renewable energy helps to reduce independence onconventional fuel resources and environmental pollutionWind power is paid attention because of:
● Low production cost
● Save land resources
● High potential
● Short time of construction

● Short time of construction
● Technologies have been developed to the provenlevel
15.06.2011
● Global installed capacity by end of 2010 is 196,6 GW.
● Only in 2010 the additional installed capacity is 37,6MW(increase of 23,6% compared with 2009)
● VN: by end of 2010, 20 turbines with total capacity of 30MWhave been installed
● According to the Strategy and Master Plan on RE Developmentfor Viet Nam up to 2015, with an extension up to 2025, RE

FUNDAMENTAL OF WIND POWER PLANNING
● Wind power is kind of energy source, thus planning must complywith technical regulations of the power sector, be compatible withdevelopment planning of other power systems and of other sectors.
● Planning of WP shall meet the following requirements:
● Consistency with local socioeconomic development plans andother related plans
● Selection of optimal sites, the effective use of the country’s

EXCLUSION AND BUFFER ZONES
● Paddy fields
● Residential or office land
● Land reserved for national security and defence
● Land for industry and production enterprises
● Land for traffic, transport routes, railways, land roads and other traffic structures
● Rivers, streams, ponds, lakes and irrigation reservoirs
15.06.2011 Seite 13Page 1315.06.2011 Seite 13
● Rivers, streams, ponds, lakes and irrigation reservoirs
● Land for cemeteries and burial grounds
● Nature reserves
● Tourist areas
● Religious or worship areas
● Protected, natural or ecological forests
These areas plus their surrounding vicinities (called ‘buffer zones’) shall be excluded to mitigate the impacts of the operation of wind turbines/wind farms on them

INFRASTRUCTURE REQUIREMENTS
● Topography
● Land type
● Access to national power grid
● Access and transportation
● Environmental issues (erosion, humidity, floods).

APLICATION OF GIS IN PLANNING
● A geographical information system (GIS) tool issuitable planning mentioned above becauseactivities such as defining exclusion areas and bufferzones, and identifying distances and suitable areasare easy to perform using GIS. Furthermore, GIS isalso suitable for managing, upgrading and reporting
15.06.2011 Seite 15Page 15
also suitable for managing, upgrading and reportingon planned areas.
● Application of MapInfo GIS.

areas)
3 wind measurement towers are installed in potential areas for 12 months to map wind potential of those areas,
15.06.2011 Seite 17Page 1715.06.2011
those areas, such as in TuyPhong, Bac Binhand Tien Thanh
The three maps are then combined into one map of wind potential.
15.06.2011 Seite 18Page 1815.06.2011
Higher potential areas are then selected (coloured areas).

INSPECTION AND SUPERVISION (1)
Supervision of technical implementation
The technique of overlapping layers by GeographicalInformation System (GIS) is new in Viet Nam. This is amodern technique, which is precise, scientific, easilymanageable, updatable and adjustable. However, it requiresthe following conditions:
● Available and suitable input data: This is an important
15.06.2011 Seite 26Page 26
● Available and suitable input data: This is an importantcondition, which decides the quality of planning.
● Planning consultant unit shall have sufficient trained staffand equipment
● Planning management unit shall have well trained,qualified staff and knowledge
15.06.2011
INSPECTION AND SUPERVISION (2)
Monitoring on environmental impacts
● The information from land use maps is not usually updated,leading to differences between what’s on the map and the actualsituation. Therefore, there is a need to compare planned ideaswith the reality on site.
● Monitoring may be easily done by comparing coordinatesobtained from portable GPS equipment with coordinates shownin the map made by software and GIS.
15.06.2011 Seite 27Page 27
in the map made by software and GIS.
● The planning management unit shall also use the sametechnique during site survey to identify possible environmentalimpacts from concrete projects of an investor. The planningmanagement unit may also provide correct advice to theProvincial People’s Committee.

LESSONS LEARNT FROM BINH THUAN PROVINCE’S CASE
Difficulties and challenges
● Lack of state regulations on contents and procedures for wind power planning
● Low awareness of wind power, its technologies as the wind power industry in Viet Nam
● Difficulty on land use planning
15.06.2011 Seite 28Page 28
LESSONS LEARNT FROM BINH THUAN PROVINCE’S CASE (2)
Questions raised during planning
● WPP is new, therefore, a methodology needs to be developed. During theplanning process, the planning consultant cooperated and shared experienceswith a German consultant (Bosch &Partner). The mapping technique, usingmap to process software and the MapInfo Program 10.0, was introduced asan advanced technique for planning in developed countries. However,because Vietnamese conditions are different to those in Germany in terms ofthe qualification and availability of databases, the planning approachaccording to the methodology presented by the German consultant is not
15.06.2011 Seite 29Page 29
according to the methodology presented by the German consultant is notvery feasible in Viet Nam.
● Criteria for exclusion and buffer areas as a basis for identifying suitable windpower development areas are not available.
● The digital maps of the current status of local land use and plans are createdby an other software, with layers which are not suitable for the MapInfosoftware; therefore, they must be converted.
● Most of the staff are not trained to use GPS software and tools.

LESSONS LEARNT FROM BINH THUAN PROVINCE’S CASE (3)
Problem solving measures
● After discussions and exchanges of ideas, the planning consultant andGerman consultants reached a consensus. National consultant developed asuitable methodology for planning which is feasible for Vietnameseconditions. This methodology was successfully used in the case Binh Thuan.
● During planning, DoIT Binh Thuan, as advisor to the Provincial People’sCommittee, prepared a temporary regulation on excluded areas and bufferzones. This regulation is temporary and effective in Binh Thuan province
15.06.2011 Seite 30Page 30
only, while waiting for MOIT to promulgate the regulation nationwide.
● The GIZ Wind Energy Project has been highly appreciated for havingproviding with specialists to revise the maps of the current status and landuse plan of Binh Thuan province, and with training and transferringinformation on MapInfo software to related staff. These maps have beenupdated and revised properly and provide important input for planning.
