Assuming that the INEEL identified hydro projects provide at least a proxy
estimate of the hydroelectric generation potential on the island, this list was used to
estimate the developable potential for the next 3, 5, 10, and 20 years. Through
conversations with developers, KIUC, and publicly available information, background
information was obtained to determine the general timeframe in which projects such as
these could be developed. The table below shows a hypothetical development timeline.
The 25 MW “Kauai” project was not included in the developable potential estimates
because of likely very strong public opposition to a hydro project of this magnitude on
the island.
