When operating at full capacity, the 28 wind turbines can generate up to 64.4 Megawatts of electricity, enough to power around 30,000 average New Zealand homes. Construction of the Te Uku wind farm began in November 2009 and is an alliance between Meridian Energy Limited and WEL Networks Limited. The alliance with Meridian was extremely successful. WEL’s key role in the project was the delivery of a new 25 kilometre transmission line and the Western Network Upgrade components, which allowed for the connection of the wind farm to WEL’s network. Additionally, with the wind farm now fully operational, its position in the central North Island is helping to increase security of electricity supply within the Waikato region and throughout New Zealand. Its commissioning takes New Zealand’s total wind capacity to 606 Megawatts. The opening ceremony for the Te Uku wind farm was attended by (left to right): Meridian Chief Executive Tim Lusk, WEL Chairman John Spencer, Prime Minister John Key, Meridian Chairman Chris Moller and WEL Chief Executive Julian Elder. OPEN DAY On Sunday 10th April 2011 Meridian held a wind farm open day. Over 2,000 people took the opportunity for a bus ride onto the wind farm site to view the turbines up close. The day also included a range of activities including kite flying at the Kopua Domain in Raglan. 20 WESTERN NETWORK UPGRADE WEL is undertaking major upgrade work as an important part of our strategy to increase the reliability and security of supply in the greater Raglan area. The work programme includes 11 separate projects, such as building new substations and upgrading others, upgrading existing lines and installing new lines both above and below ground. The western network upgrade began in 2005 and will be largely complete by 2013. A major milestone was reached in October 2010 when WEL completed the construction of the new 25km 33kV electricity line, which connects the Te Uku wind farm near Raglan with local substations. An upgraded circuit for the wind farm was completed in Jan 2011. The project included eight kilometres of undergrounding and was constructed in just 31 weeks. It is the largest new line build project ever undertaken by WEL and the largest line build project by an electricity distribution company in New Zealand in 2010. The current work programme includes the construction of a new substation at Raglan. THE NEW WHATAWHATA SUBSTATION RAGLAN ZONE SUBSTATION The Raglan zone substation has been in concept form for many years as part of our long term planning to upgrade supply to our western network. The new substation project was brought forward as a result of the construction of the Te Uku wind farm and is designed to take load from the existing substation. The substation will increase security of supply to the area and will also improve the quality of that supply and provide for future load growth in urban, rural and lifestyle areas around the greater Raglan community. The project started on the 22nd of February, 2011 and the expected end date is December 2011. The project cost is approximately $3.5 million and much of the substation fit out is being undertaken by WEL. ARTIST’S IMPRESSION OF THE NEW RAGLAN SUBSTATION. 21 PHOTOVOLTAIC TRIAL Raglan’s Community House and the Greenspace meeting venue in Hamilton have been chosen by WEL as the sites participating in a trial funded by the WEL Energy Trust to test the feasibility of distributed generation using small-scale solar technology. The 1.2 kilowatts photovoltaic systems were installed by WEL during November 2010. The trial is one of the innovative ways WEL is looking at managing increasing demand on our network more efficiently. Alternative technologies such as solar distributed generation may assist with demand management without the need for costly network expansion and new infrastructure. The photovoltaic system being trialled by WEL is a form of distributed generation, or generation of energy close to the point of use. Any excess power generated and not used by the occupants of the above sites, can be sold to their electricity retailer. If the trials provide the anticipated advantages, rolling them out to the mass market could also help save customers money on their power bills while providing environmental benefits. HEALTHIER HOMES The WEL Energy Trust Healthier Homes Programme is managed by WEL and supported by the Energy Efficiency and Conservation Authority, Hamilton City Council, Sky City Hamilton Community Trust and DV Bryant Trust Board. The programme is helping people in need or on low incomes who have health issues. It is delivering considerable benefits to the local community by ensuring inadequately insulated predominantly pre-2000 homes are brought up to today’s building insulation standards. The home retrofit improvements included within the programme are: • Ceiling insulation • Under floor insulation • Ground moisture barrier • Hot water cylinder wraps • Cylinder pipe lagging PHOTOVOLTAIC PANELS BEING INSTALLED ON RAGLAN’S COMMUNITY HOUSE. 22 NEW NETWORK MANAGEMENT SYSTEM WEL has successfully implemented a new Network Management System (NMS). The NMS includes: • SCADA (Supervisory Control and Data Acquisition)-providing the control for and showing the state of the network • DMS (Distribution Management System) shows the network (11 kilovolt and 33 kilovolt diagrams) and other tools including permitting and switching with advanced safety logic • OMS (Outage Management System) links the customer information with faults and deals with the outages PROJECT TEAM FOR THE IMPLEMENTATION • TCS (Trouble Call System) links dispatch OF THE NEW NETWORK MANAGEMENT SYSTEM and call centre functions • Load control to manage network peaks • Reporting to the business and other users This has been a major project for the Company, commencing in 2007 and involving a wide range of WEL staff and external experts. The new system will contribute to higher levels of safety, security and efficiency across the many facets of managing WEL’s network. RESIDENTIAL WIND TURBINE TRIAL The Raglan Area School was chosen by WEL to participate in a residential wind generation trial funded by the WEL Energy Trust. The trial is looking at the practicalities of small- scale wind technology as a form of distributed generation, or generation of energy close to the point of use. The 1.9 kilowatt Skystream turbine used for this trial is manufactured in the United States and has been especially designed for use in coastal regions and residential areas. It is the first installation of the technology into a school located in a residential area in New Zealand. The wind generation trial is part of a programme at WEL that is looking at innovative ways to manage and reinforce our network to improve capacity and reliability. It is an opportunity for the public to have a look and learn more about the possibilities of small scale wind RAGLAN AREA SCHOOL PRINCIPAL, generation.
