British Columbia香蕉视频直播檚 coastal lighthouses are going green. Not the colour: they will remain red and white on the outside. However, their power sources are turning to renewable energy.
香蕉视频直播淲e have 27 staffed lightstations. So far we have four that have renewable systems installed,香蕉视频直播� says Shaun Loader, senior project engineer with Fisheries and Oceans Canada. 香蕉视频直播淣ext year we香蕉视频直播檒l have six more that are going to be upgraded to the same system.香蕉视频直播�
Renewable systems include battery banks, inverters, solar panels and wind turbines.

Coastal B.C.香蕉视频直播檚 lightstations have traditionally run on diesel generators. Now that those generators are approaching the end of their life, stations are being converted to renewable energy sources. It香蕉视频直播檚 a more cost effective way to power lightstations, Loader explained, especially when the cost and difficulty of delivering diesel to the stations are factored in.

There are already four lightstations that are in various stages of conversion: Entrance Island at the mouth of Nanaimo Harbour, Merry Island on the Sunshine Coast, Boat Bluff near Bella Bella and Cape Scott at the north end of Vancouver Island. While the conversion systems are modular, each combination will be customized to the individual stations depending on whether they get more sunlight or more wind, Loader explained.
Timing for construction will depend on the weather windows: long stretches of calm weather will mean the work will be done faster.

The six stations expected to convert to renewable energy sources in 2019 are Carmanah on the West Coast Trail, Cape Beale (also along the West Coast Trail), Lennard Island off Tofino, Estevan Point, Ivory Island and Green Island, just off of Prince Rupert.
Work has already begun on the Cape Beale lightstation, which will receive two, 5-kilowatt solar arrays and two, 3Kw wind turbines, an inverter and battery bank system by the end of 2019. The cost to upgrade Cape Beale, for instance, will run around $300,000 ($40,000 for the battery bank, $100,000 for solar and $150,000 for wind turbines).
The payback for conversion won香蕉视频直播檛 take long. It costs between $30,000 and $40,000 per year for diesel per lightstation, and that doesn香蕉视频直播檛 include delivery and crew costs. With Cape Beale香蕉视频直播檚 combination, for example, 香蕉视频直播渋t will be just under four years of payback.香蕉视频直播�

The diesel generators won香蕉视频直播檛 be removed completely, Loader said. They will be replaced as they reach end of life; lightkeepers just won香蕉视频直播檛 depend on them as much as they do now.
