- The shares touched 8p last Autumn following the recovery from near-failure. They ran up
again to the 8p level as battery prospects started to be recognised; but the fund raising at 4p in June
really hit the shares. I think this gives us a good buying opportunity. Please note the revenue decline is
misleading. It reflects the restructuring of the business and the associate status of the battery interests.
last November and is backed with £3.6m funding from the Department for Energy and Climate Change.
Gigha has limited connection to the grid via an old subsea cable, though it does have three wind turbines
with a fourth being added. However because of the “constrained power” problem I described above,
this new turbine alone will lose around £300,000 worth of electricity that it could have generated over its
25 year life. The constraint also stops other renewable capacity from being added on the island.
Camco’s flow battery should mean at least a 20% increase in wind power generation as the
constraint is removed. It will also allow the smoothing of supply to match consumption patterns
and sales of surplus power into the grid. It’s a similar timing story with solar power. Here Camco
already has a small system in operation at a university site in Evora, Portugal as part of an EU
backed scheme.
The market potential is large. According to the government there are over 5,300 small wind
farms in the UK. Camco’s battery might be relevant for over 2,000 of these. In solar there are over
10,000 suitable installations in this country. Given the project on Gigha it’s worth noting that there
are almost 5,000 islands around the world with a population under 1,000. Looking at Germany, a big
renewables market, there have been over a million solar installations made since 2000 which are the
right size for flow battery technology. The market is plenty big enough in renewables.
Two important markets for Camco
But Camco’s batteries don’t just work with renewables. The second problem Camco solves is power
generation at other locations that are off-grid like remote communities, mines and telecom towers.
These sites tend to rely on diesel generators, but there is a big opportunity to combine these
with a flow battery. Just running a diesel generator on its own results in high fuel and maintenance
costs. But if a flow battery is charged up by the generator at the same time it’s powering a telecom
mast for example, the battery can take over for a period and allow the generator to be shut down
and rested. Running the generator for fewer hours makes it last longer, saving on maintenance and
replacement costs. Fuel efficiency is also improved because the generator can run at a constant load,
rather than having to modulate its output. As the mast’s power demands vary the flow battery can
kick in to top-up supply. Camco expects a battery investment to have a four-year payback f
