Data center study (2026): HCR 206 HD1 and HR 196 HD1, adopted in April 2026, ask the Hawaii State Energy Office to convene a working group on how data centers of 5 MW or more would affect utilities, ratepayers, water and climate goals and to report before the 2027 session; the resolution notes Hawaii had not yet received a hyperscale proposal. (Hawaii State Legislature, April 1, 2026; Civil Beat Digital Democracy (legislative status tracker), April 27, 2026; Hawaii State Legislature, April 1, 2026; LegiScan (legislative status tracker), April 9, 2026) The Senate's version, SR 90, was reported out of committee as amended (SD 1) on April 8, 2026, adding study items such as a megawatt threshold for a large data center, on-site backup power that can curtail load in grid emergencies, independently verified energy and water reporting, and ties to the PUC's integrated grid planning; the concurrent SCR 95 SD1 was referred to House committees on April 10. Civil Beat reported the working group first met in September 2026.
