Whenever mainland transplants bring up the subject of Hawaii electricity, almost all fail to recognize the plantation era effect. This mainland connotation "grid" the ignorant keep being fixated on, is actually a micro-grid on each island. The plantation infrastructure put all these oil burning electric plants in as micro-grids, long before it became an emofanatic buzz word among ignorant transplants to Hawaii in the second decade of the 21st century. The sugar and pineapple *ag* export industry required that much electric power, nothing else on these islands did, except the military and they built their own diesel-electric plants. During that 100 years from 1860 to 1960, most plantation workers didn't have electricity for their residences, which were leased from the plantation. Plantation housing, plantation stores, plantation infrastructure. Tourism started requiring more and more electricity, the plantations had excess electric power and started running lines into towns and residences, for a metered fee.
These are not "grids". These are micro-grids, specific to each island, and even then, more accurately, are micro-rings, not grids. Grids criss-cross over each other and they don't here due to the geography.
Hawaii electric rates are about 90% referenced to the price of a barrel of oil. These stats don't have to be guessed at, they can be looked up, although not easily.
Hawaii Electric is required to make a request to the PUC when they need an electric rate increase. However, they don't need to make a request to lower rates. The rate is being lowered. The collapse in oil prices is only about two months old. There was a slight rate drop in November. In December, the HELCO electric rate decreased by 3.5%. If the oil collapse continues, the rate for January may be much more significant.
Only been saying this to idiots for 3 years. The Hawaii electricity rate is majority share referenced to the price of a barrel of oil. And there it is, in their monthly rate report, HELCO was buying oil at $95 per barrel during December. The Hawaiian Electric website is actually a wealth of information for those that don't have totally closed minds.
