Maui energy storage study.
Abstract
This report investigates strategies to mitigate anticipated wind energy curtailment on Maui, with a focus on grid-level energy storage technology. The study team developed an hourly production cost model of the Maui Electric Company (MECO) system, with an expected 72 MW of wind generation and 15 MW of distributed photovoltaic (PV) generation in 2015, and used this model to investigate strategies that mitigate wind energy curtailment. It was found that storage projects can reduce both wind curtailment and the annual cost of producing power, and can do so in a cost-effective manner. Most of the savings achieved in these scenarios are not from replacing constant-cost diesel-fired generation with wind generation. Instead, the savings are achieved by the more efficient operation of the conventional units of the system. Using additional storage for spinning reserve enables the system to decrease the amount of spinning reserve provided by single-cycle units. This decreases the amount of generation from these units, which are often operated at their least efficient point (at minimum load). At the same time, the amount of spinning reserve from the efficient combined-cycle units also decreases, allowing these units to operate at higher, more efficient levels.

Volume I presented the current energy picture of Maui county, while Volume II projected a number of tentative energy scenarios. This volume, Vol. III, comprehensively analyzes the future of energy in the county and selects the most-probable scenario. The scenario assumes Maui County's present high growth rate will eventually drop to a moderate and then a low rate. The county can reach energy self-sufficiency in 1995 at a cost of $710.9 million. The major natural energy resouces are the indigenous ones: geothermal, biomass, wind, and solar. Conservation, of course, will play an important role. An energy plan is drawn up,more »

Energy self-sufficiency fo the county of Maui. Volume 1. Energy data update
The basic energy data from which a Maui County energy self-sufficiency development and implementation plan will be drawn are presented. Treatment has been restricted to a number of comparative analyses, a comprehensive representation of the present energy picutre for Maui County, and future energy trends. It is concluded that petroleum is the key fuel that needs to be substituted. Although Maui is the chief petroleum consumer in the County, a significant portion of the total energy budget includes alternate sources such as bagasse and hydroelectric power. Molokai and Lanai are totally dependent on petroleum. It will be a major challengemore » -
Study of the feasibility of linking the islands of Maui, Molokai, and Lanai with submarine electrical power cables
The feasibility of linking the islands of Maui, Molokai, and Lanai with submarine electrical cables was studied. A summary of the background leading to this study, the reasons for the proposed system, the objectives of this study, the methods used, and the findings obtained to date are outlined. The requirements for linking the islands are discussed. Information regarding the submarine power cables recommended for the proposed installation; possible causes of electrical submarine transmission system failures (electrical faults, physical damage, corrosion of cables); general criteria used for the selection of submarine cable routes; and estimations of cost and time requirements formore » -
Native Hawaiian Ethnographic Study for the Hawaii Geothermal Project Proposed for Puna and Southeast Maui
This report makes available and archives the background scientific data and related information collected for an ethnographic study of selected areas on the islands of Hawaii and Maui. The task was undertaken during preparation of an environmental impact statement for Phases 3 and 4 of the Hawaii Geothermal Project (HGP) as defined by the state of Hawaii in its April 1989 proposal to Congress. Since the state of Hawaii is no longer pursuing or planning to pursue the HGP, DOE considers the project to be terminated. Information is included on the ethnohistory of Puna and southeast Maui; ethnographic fieldwork comparingmore »
