Home Letters Golden small-scale hydro-power opportunity
Dear Editor,
The Government, in partnership with the IsDB, recently placed an advert in the paper for hydropower design and construction services. Upon seeing this, I started to reel.
In my letter to the Editor, titled, “Will Guyana take advantage of these remarkable victories in sustainable energy generation?”, I present the current view of renewable energy implementation in the context of a traditional power grid.
Power coming from solar panels will be mediated by software systems being powered at first by batteries at home. These home systems use the internet to signal the transfer of power across the network, sharing power among homes when panel production exceeds consumption and battery storage. Together, and at given moments, all the homes in a battery-networked neighbourhood may produce more power than they consume. This excess of power would then be transferred to nearby consumers – like dense, more vertically-constructed population centres that lack rooftop space, or industrial estates; or, in the case of Australia, entire city centres. Homeowners may even earn money by generating power for the grid.
At the utility scale, software will allow wind, solar, fuel and other sources to co-operate in an intelligent manner. Wärtsilä tested such a software system in an undisclosed location. In that test, fossil fuel generator usage was cut back by 80%. They used the same dual-fuel engine deployed here in Guyana.
In that same letter, I briefly mentioned Turbulent turbines. I feel urged to suggest that this solution might be ideal for rural communities in need of hydropower solutions. Turbulent is a company based in Belgium with experience delivering hydropower implementations in the region, more specifically in rural communities in low-income countries. They recently deployed one of their turbines in neighbouring Suriname. The Turbulent turbine does not block waterways. Turbines can be instantiated almost indefinitely along the sides of streams, meaning that you can add more and more turbines over the
long term, to the same stream. These ‘top-down’ turbines are a demonstrated solution that protects wildlife, does not adversely affect the flow of an attached stream, and can be scaled to meet any power requirement, large or small.
Here is a link to a very friendly page on their site, where organisations can submit details about proposed hydropower projects https://www.turbulent.be/for-whom. If the Government is already on to this, then colour me excited.
Sincerely,
Emille Giddings
