“Water/Energy Nexus: Business Case for Renewable Energy and Energy Storage for Water Agencies”
I built the Capital wind farm which powers the City of Sydney desalination plant and is helping Sydney face the current drought.
A similar solution to the water/energy nexus is available to the 40 million residents in the West facing the drought as described below.
• The importance of this topic;
The water/energy nexus is a critical issue for federal water and energy agencies in the West (DOI, Burec, BLM, DOE) and state (MWD, LADWP, Salt River Authority) and local agencies egiven the 4 million- acre feet (MAF) shortfall (drought) projected for the Colorado River Basin.
To meet the 4MAF shortage, water agencies are planning 9 desalination plants in California.
The power required to desalinate 4MAF of ocean water is on the order of 3 to 5GW.
The price of electricity is major operating cost for water treatment plants and the utility rates are projected to increase significantly in the event of a drought due to loss of hydro power.
Reliability of electric service is critical to meeting customer satisfaction goals, particularly in the event of a 4 MAF drought by 2030 in the West.
• The informative and relevant nature of your topic;
Solutions to the water/energy nexus via Renewable Energy and Energy Storage is an informative and relevant topic which can improve the security, well-being and prosperity of over 40 million residents.
• Clear and immediate application to the learner’s work;
Planning would need to start today by local, state and federal agencies and NGO stakeholders and public on 4MAF desalination project powered by 3 GW to 5GW Renewable Energy and Energy Storage system given there is only 11 years before the 2030 projected drought and given that typical infrastructure projects take a decade of longer to implement as was the case for the City of Sydney desalination plant.
• Who will benefit from this education (target audience).
The water masters in the West and their 40 million plus customers can benefit from this paper as well as other water masters and clients interested to find solutions to solve the water /energy nexus challenge in their area
