An update briefing meeting to the whanau at Omaio marae where the winning three student engineering design teams presented their ideas and plans to create a flagship maori community owned renewable energy enterprise. Stunning ideas from the students with lots of questions and feedback from the whanau. The next steps are now to assemble an expert engineering review panel to consolidate all the best ideas and develop a final business case with detailed cost/benefit analysis that will be socialised with the investment community towards making the project real by the end of 2014.

- Partnership strategy We have no money; Acknowledge the sponsorship of Environment Bay of Plenty, and Mangaroa Ohotu & Te Karaka Land blocks Estimate the cost to get us to the point we are at now would have been between $200,000 to $300,000.
- Introduce myself Great to be back Acknowledge important people

- Anerobic digestion breaks down greenwaste and wastewater into solids and gas. The gas contains a large amount of methane so can be used for cooking and heating. New Zealand designed and built. Waste Action from Nelson but haven’t heard back from them re cost Cost depends on installation

Larger systems could return about 9 per cent, Winitana said. “

- Biomass + wind + solar Complement each other Limited amount of electricity that network can accept. Generation needs to be near to transformers About 3MW safely but in the hands of Horizon Energy company only has to accept upto 10kw of power input Many of the remote lines that were installed under government subsidises during the 1940’s-1980’s are nearing the end of their design life. The replacement of these lines with a stand-alone power systems may, in some cases, be a more economical means of providing electricity than replacement and ongoing maintenance of these remote lines (Empower Consultants, 2008). Presently the maintenance of these lines is effectively subsidised by consumers in areas where electricity distribution is financially viable.
- Tokelau 2012 the first country powered by solar. 1 MW Implementation by NZ company PowerSmar Westmill Solar Co-operative owns and operates the first community owned solar farm in the UK - hopefully of many to follow - and we believe we are the largest community owned solar project in the world. The solar farm is rated at 5MW, located on the Oxfordshire/Wiltshire border, spread across 30 acres, read more in the Solar Park section. We have over 1600 members who share a say in how the cooperative is run and benefit from a share of the project revenues.
- Solar Photovoltaic panels are a scable way of generating electricity to sell to the network All hapus have good solar resource Each hapu own ‘farm’ of 100m2 of panels gives a balanced generation across a connection point into the lines distribution network. Helps if the network distribution system is not good by having the generation closer to its usage point. Meet 90% of local demand over a year Ground mounted sun tracking Kyocera panels for optimum efficency Change at 1:30
- Deger available from NZ Solar Farms in Nelson Photovoltaic modules that follow the sun’s path capture a higher amount of energy and therefore produce decidedly more power than modules in a fixed installation. The tracking system moves to the ideal position from sunrise to sunset and produces more energy than fixed systems. The advantages are clear: an average of 45 percent higher energy yield compared to fixed solar modules less module space required constant energy production - also in the morning and evening, when the demand for energy is at its highest

- Simplified versions of smart networks, with generation and storage capacity, could be used at the end of long grid lines where voltage support is needed. The local inverter would supply peak demand at the end of the line, reducing the capacity requirements on the line. In some cases the line may become obsolete altogether. This may be used as a transition strategy in remote areas, if the economics of maintaining grid lines are poor. It would allow customers to gain confidence in the new technology before connection to the grid is severed and also allows staged capital expenditure.
