What a week! It feels
as though an eternity has passed since the Komawai reappeared on the horizon
with our two missing comrades and remaining equipment aboard. It was only 8
days ago.
The unloading process
recommenced last Saturday and after almost two weeks holding our collective
breath, there was a shared sigh of relief with the arrival onshore of our
crates. In two of these; our much longed for food supplies. In a third; our
bicycles. And last but not least, the tools we’d need to start work.
By Monday night we
were loading the civil equipment for McConnell Dowell that will now go on to
Nanumea including a tractor, trailer and one of the excavators. In the fading
light, finally independently mobile and re-energised on spaghetti, chocolate,
muesli and tinned peaches, we started to feel like ourselves again.

On site Tuesday
morning, the chaos started to give way to order. By mid-afternoon I’d realised that my most valuable tool
through the months ahead is going to be my steel hunting knife that Shane made me
buy the day before we left. I can tear through the most stubborn packaging
tape. And I’m learning to open my own coconuts.
By Tuesday afternoon,
tool boards were up, building mark-out was complete, a mountain of packaging
had collected behind the powerhouse and the first battery rack jigsaw puzzle
was spread across the floor. Under torchlight Tuesday night, we measured and
marked drilling holes for the first array. We were underway.

Our schedule over the
next 5 months has us partially completing the system on Vaitupu before moving
on to Nanumaga, Nanumea, Niutao and returning to Vaitupu late May to complete
the main array. Groundwater issues discovered when clearing the site in
November resulted in McConnell Dowell halting work on the main array foundation
until an engineering solution is agreed with MFAT and the local Kaupule
(council). The McConnell Dowell team is due back here after we leave to
complete foundation works. Our hope is to have the powerhouse fit-out and
smaller battery charger array complete by the time we leave here in just under
3 weeks time.

And we think that is
achievable. Our local workers have earned our immediate respect for their
positivity and strong work ethic. By Thursday morning our team had grown from 5
to 15. And they would work 14 hours a day if we felt we could keep up with
them!
In efforts to manage
our enthusiastic workforce, we have split off into three clearly defined teams:
Hadley’s electrical team, Roger and Marty’s array team and Heather’s battery
team. Shane likes to think that we are all his team.
In the inverter
corridor, Hadley has been orchestrating a fine ballet. Alongside him, File
keeps asking questions about what all the equipment is and Vilium, Aneila and
Paka are unflinching when told that half the inverters now have to be taken
down and moved 200mm to the left (thanks to the inaccurate drawing). The
electrical crew now have all the inverters mounted, the multi-cluster box in
place and cable tray ready to fill. Visible progress is fast but will slow from
here as they begin the complex cabling process.
Outside, camaraderie
in the array team is at an all time high. Three days in and they’ve knocked up
a 50kW array. Working out in the heat, regular coconut stops are essential. One
of the local boys scrambles up a 20m high tree like it’s a staircase. Epati,
Bean, Konza, Ety and Sammy have lanolin dripping down their arms from the
freshly lubricated bolts. Dropping one in the sand earns a jibe from Roger –
“fall behind and you’re next up the coconut tree”. On Monday they start
tightening fastenings, grouting trestle feet and digging trenches for the
cabling. Another 360kW still to go in May will be a walk in the park.
SIC array framing went up in a day |
In the battery room
it’s all I can do to stay one step ahead of Bob, Eddi and Puaa. When we opened the
first battery rack on Tuesday my only head start was a technical drawing and
some notes from Dean. I try to anticipate the next question and am grateful for
their patience when I demand for the seventh time that we recheck the diagonals
to make sure it’s square. It’s a slow process but they will be a well-oiled
machine by rack number 12. Just in time to move onto Nanumaga and start all
over again with a new crew.
Hot on their heels,
the battery loading team of Peter, Fata (Greenstuff), Teanua and Polevia are
carefully and steadily lifting and positioning batteries. At 200kg each, a
dropped battery will crush your foot. One rack holds 48 batteries and each must
be lifted into place and slid onto the rack in the right position ready for
connection. The dangerous process of connecting batteries is on hold until we
can clean many of the connecting cables that have corroded in transit and
storage.
At the end of week 1
we have 3 ½ battery racks built, 2 ½ now stacked with batteries. The 55kW Sunny
Island Charger array is up. The inverter corridor looks almost finished with 36
Sunny Island inverters, 12 battery disconnect boards, 24 Sunny Island Chargers
and 15 Tripower solar inverters and switchboards all hanging. The multicluster
box is in the building, cable tray is up and the real work begins tomorrow.
