It is good that the new regime is setting out targets as part of what appears a thought through, coherent plan. Everything except coal is new to the Botswana energy mix - CBM has been kicked around for nigh on 20 years so there must be major doubters there that it is viable. 10MW by 2025 is a sign they want it proved first before Ministry will get behind it.
By far the easier path is to extract the gas and run it through Orapa 90mw - prove that the gas can be extracted in commercial quantities, delivered to a power station gate, burned through a power plant, and learn all the resultant issues. Then, if successful, scale up by building modular plants in a few suitable locations supplied by pipelines. Should also greatly save effort and cost if transmission lines getting power to grid. Simple really - note the IRP said ‘energy at least cost’
