Kalaeloa Energy System Redevelopment Options Including Advanced Microgrids

Hightower, Marion M.; Baca, Michael J.; VanderMey, Carissa V.

In June 2016, the Department of Energy's (DOE's) Office of Energy Efficiency and Renewable Energy (EERE) in collaboration with the Renewable Energy Branch for the Hawaii State Energy Office (HSEO), the Hawaii Community Development Authority (HCDA), the United States Navy (Navy), and Sandia National Laboratories (Sandia) established a project to 1) assess the current functionality of the energy infrastructure at the Kalaeloa Community Development District, and 2) evaluate options to use both existing and new distributed and renewable energy generation and storage resources within advanced microgrid frameworks to cost-effectively enhance energy security and reliability for critical stakeholder needs during both short-term and extended electric power outages. This report discusses the results of a stakeholder workshop and associated site visits conducted by Sandia in October 2016 to identify major Kalaeloa stakeholder and tenant energy issues, concerns, and priorities. The report also documents information on the performance and cost benefits of a range of possible energy system improvement options including traditional electric grid upgrade approaches, advanced microgrid upgrades, and combined grid/microgrid improvements. The costs and benefits of the different improvement options are presented, comparing options to see how well they address the energy system reliability, sustainability, and resiliency priorities identified by the Kalaeloa stakeholders.

Cost estimate for a proposed GDF Suez LNG testing program

Brady, Patrick D.; Jernigan, Dann A.; Lopez Mestre, Carlos L.; Luketa, Anay L.; Nissen, Mark R.; Hightower, Marion M.

At the request of GDF Suez, a Rough Order of Magnitude (ROM) cost estimate was prepared for the design, construction, testing, and data analysis for an experimental series of large-scale (Liquefied Natural Gas) LNG spills on land and water that would result in the largest pool fires and vapor dispersion events ever conducted. Due to the expected cost of this large, multi-year program, the authors utilized Sandia's structured cost estimating methodology. This methodology insures that the efforts identified can be performed for the cost proposed at a plus or minus 30 percent confidence. The scale of the LNG spill, fire, and vapor dispersion tests proposed by GDF could produce hazard distances and testing safety issues that need to be fully explored. Based on our evaluations, Sandia can utilize much of our existing fire testing infrastructure for the large fire tests and some small dispersion tests (with some modifications) in Albuquerque, but we propose to develop a new dispersion testing site at our remote test area in Nevada because of the large hazard distances. While this might impact some testing logistics, the safety aspects warrant this approach. In addition, we have included a proposal to study cryogenic liquid spills on water and subsequent vaporization in the presence of waves. Sandia is working with DOE on applications that provide infrastructure pertinent to wave production. We present an approach to conduct repeatable wave/spill interaction testing that could utilize such infrastructure.

Evolution of Sandia's Risk Assessment Methodology for Water and Wastewater Utilities (RAM-W™)

World Environmental and Water Resources Congress 2010: Challenges of Change - Proceedings of the World Environmental and Water Resources Congress 2010

Jaeger, Calvin D.; Hightower, Marion M.; Torres, Teresa M.

The initial version of RAM-W was issued in November 2001. The Public Health Security and Bioterrorism Preparedness and Response Act was issued in 2002 and in October 2002, version 2 of RAM-W was distributed to the water sector. In August 2007, RAM-W was revised to be compliant with specific RAMCAP® (Risk Analysis and Management for Critical Asset Protection) requirements. In addition, this version of RAM-W incorporated a number of other changes and improvements to the RAM process. All of these RAM-W versions were manual, paper-based methods which allowed an analyst to estimate security risk for their specific utility. In September 2008, an automated RAM prototype tool was developed which provided the basic RAM framework for critical infrastructures. In 2009, water sector stakeholders identified a need to automate RAM-W and this development effort was started in January 2009. This presentation will discuss the evolution of the RAM-W approach, capabilities and the new automated RAM-W tool (ARAM-W which will be available in mid-2010). © 2010 ASCE.
