Understanding Embedded Energy in Water - Concepts, Tools, and Opportunities

9.00 - 9.30 am

Making progress in the water-energy nexus requires an understanding of how the two industries are related, particularly how California's water infrastructure uses energy. As we plan to upgrade our water and energy infrastructure in the future it is imperative that we begin to think in an integrated fashion. This presentation will discuss the historic statewide perspective of energy use by the water sector, discuss methods and processes to develop a deeper understanding of energy use by retail water systems, and discuss how this information can be used to better inform energy decisions by water utilities.

Bridging the Divide: The Challenges of Integrated Resource Management for Water and Power

9.30 - 10.00 am

Reliable, equitable access to energy and water are essential for a resilient society - one having a sustainable resource base and a robust economy. Despite strong interdependencies between these sectors, joint solutions are difficult to integrate because each sector's services are provided by different entities, and regulated by separate agencies. Innovation in the energy and water sectors is needed to: achieve climate change mitigation and adaptation; understand how combined water-energy systems might behave under future conditions; attain a strategic vision to enhance water and energy system resilience (e.g., managing drought); and, improve resource efficiency -- the water delivered per unit of energy expended, and the energy delivered per unit of water used.

Innovation requires (1) a shared systems understanding that simulates the behavior of the combined water-energy system; (2) data and analytics that inform shared system development; (3) meaningful measures of impact and overcoming logistical barriers; (4) expeditiously diffusing innovations, (5) strong inter-organizational partnerships; and (6) data platforms that protect proprietary information while facilitating data sharing. The presentation concludes by focusing on emerging lessons for California based on current research which suggests that: adaptation actions are unlikely to approach their full potential for cost-effective risk reduction without investments of policy, management, and financial resources. Many strategies will involve high capital costs, and social acceptance of some alternatives may be limited.

The Water-Energy Innovation Gap

11.00 - 11.30 pm

Regions around the world face a future of increasing energy demand and water variability, but they have yet to unleash their collective potential to innovate. Supply disruptions are already affecting business in California, China, India, and elsewhere. This is true not just for the electric power and water industries, but for customers and communities who rely on them. This is not strictly a supply problem -- nor a problem that water or power companies can solve alone. It is just as much a demand challenge, and therefore an opportunity to expand the scope of innovators who have "skin in the game" when it comes to securing future energy and water resources. If necessity is the mother of invention then those who need and use water and energy the most will be the best partners in finding ways to address demand. Companies and countries alike must find new ways to work with stakeholders who can help change the way we manage the world's most important resources.

Technology Advances and Innovations for Ensuring Sustainable, Clean Water

11.30 - 12.00 pm

Roughly 10% of the earth's population is forced to rely on contaminated water sources for basic needs. As climate change and other demographic trends increase the stress on available water sources, the urgeny of providing adequate, clean water to people in developing and rural areas becomes more acute. Additionally, industrial countries must also meet the needs of urban areas with deteriorating water systems, while new investment and improvements are being planned and deployed (eg., Flint, Michgan). This presentation will discuss new technology advances that are enabling clean, safe, and sustainable water supplies to remote and rural areas, many of whom also lack power from the grid. It will also take a look at the water-energy nexus from an international perspective, with particular focus on the evolving water needs of an increasingly decentralized grid.

Integrating Renewables and Achieving Cost Savings with Battery Storage

1.00 - 1.30 pm

Battery storage has successfully been integrated into a complex energy portfolio at the Inland Empire Utilities Agency (IEUA). Battery storage has initiated a shift from grid independence to grid interdependence with the ability to work with investor-owned utilities to ease grid demand when needed. IEUA has found that the storage technology lends itself toward applications in the wastewater industry, where facility loads are fairly predictable.

This presentation discusses a microgrid deployment at IEUA, in which battery storage will interconnect with IEUA's generation sources to provide a level of control for power distribution and achieve cost savings through strategic electricity procurement. A total of 7.3MWh of battery storage will be installed across six IEUA facilities, with each applying sophisticated analytics software to optimize electricity purchases and meet each facility's energy needs in the most cost efficient manner. The batteries will also serve to enhance IEUA's demand side management and improve the ability to assist the electric utility in times of high grid demand.

Legal and Regulatory Influence over the Water/Energy Nexus

1.30 - 2.30 pm

This panel will focus on legal and regulatory issues affecting the water/energy nexus. There are myriad ways in which legal requirements impact the connection between water and energy. On the energy side, environmental regulations may impact the use and disposal of water used for energy production and generation. On the water side, regulations may impose compliance obligations on energy used or generated by water projects. From fracking to cap-and-trade, this panel will discuss some of the major ways in which state and federal regulations impact the water/energy nexus, and how that impact influences the operations of water and energy companies.

Getting Out of Hot Water: Energy Savings Potential in the Water Sector

4.15 - 4.45 pm

Nineteen percent of California's energy is used by water utilities for conveying, treating and distributing water. Right? Well, not quite. Understanding where electricity and natural gas is used in California's water sector is critical for developing successful partnerships between water agencies and energy utilities. This presentation will unpack the nineteen percent and cover:
  • Trends in California's water-related energy use
  • Energy savings opportunities in the water sector
  • How Metropolitan and other water utilities are addressing the water energy nexus

Distributed Energy Resources (DERs) from the Water-Energy Sector

4.45 - 5.15 pm

Southern California Edison (SCE) will be conducting a scaled deployment in 2017 to study the application of both pumped water storage and load shifting as distributed energy resource (DER) solutions to address the oversupply of renewable generation on the electrical grid (Over-Generation). SCE believes there is also potential for this customer sector to develop innovative "fast and flexible" operational strategies to meet the demand side ramping needs for Over-generation, and that the potential for water storage strategies for Over-Generation has not been fully investigated. The Over-Generation Pilot will also provide SCE with information and insights necessary to establish effective over-generation pricing strategies, and the investigation will help SCE determine if an over-generation mitigation program involving water pumping, treatment, and storage is feasible and would deliver significant and effective results. This presentation will identify the definition of Over-Generation, and how the activity will focus on demand side water pumping and water conveyance and processing applications to offset the increased availability of renewable generation on low demand days, allowing a more seamless utilization of renewable generation into the electric grid.

Water Conservation: Why Do Energy Utilities Care?

9.00 - 9.30 am

Customers across all market segments are acutely aware of water constraints in California. PG&E is operationalizing a Water-Energy Calculator to calculate embedded energy in water savings for the pumping and treatment of water and wastewater. This tool will allow PG&E to assist customers in achieving their water conservation goals while continuing to support traditional energy efficiency needs. PG&E's proposed entry into this program area is to begin with measures that share direct water and energy savings before moving in to other program models with only water savings. Key market opportunities include residential indoor and outdoor programs, as well as agricultural irrigation water use efficiency. In preparing for these new programs, PG&E solicits input from water agencies on how PG&E can assist water agencies in expanding their current offerings or establishing new conservation programs. By leveraging water agency expertise in water conservation and PG&E's breadth of customers across the state, PG&E is confident that more can be achieved through collaboration than through working alone.

Improving the Efficiency and Reliability of Water Systems Using Data Analytics

11.15 - 11.45 am

The energy content contained in supplying water to society is a significant portion of the total cost of water resources. Approaches to improving the energy efficiency of water systems often focus on replacement of capital equipment with more modern and efficient products. These remain valid approaches, but there is now another tool in the toolbox -- data analytics. Data analytics can automatically identify operational issues and inform operators through clear, intuitive displays. The use of data analytics for water systems will be highlighted through a number of examples including: detecting water loss (leaks), detecting equipment degradation trends, detecting overridden or failed controls, and detecting failed sensors.

Embracing Disruptive Technology for Water Utility Optimization and Energy Efficiency

11.45 - 12.15 pm

Utilities require large sums of money to operate, maintain and replace their assets while being continually squeezed to do more with less. Water utilities are typically large electrical users and pay substantial electrical bills. However, early-adopting utilities that embrace new disruptive technologies operate more efficiently, are more responsive to customer needs, and maximize capital expenditures. With new business intelligence comes the need for a work force that can support the new data systems and interpret new insights for the benefit the water-energy utility and its customers. The challenge for the utility staff is two-fold: 1) understanding how to use the technology to its fullest potential; and, 2) communicating the benefits to customers.

This session will walk through the latest disruptors, outlining a step-by-step process of how to leverage the tools and information throughout your organization with a strategic focus on water-energy efficiency. Key Takeaways:
  • The utility organization paradigm shift that is required as a result of disruptive technologies
  • Steps to ensure disruptive technology projects provide maximum value throughout the organization
  • How to adopt a disruptive approach to improve water-energy efficiency initiatives

The Estimated Impact of California's Urban Water Conservation Mandate on Electricity Consumption and Greenhouse Gas Emissions

1.15 - 1.45 pm

In April 2015, the Governor of California mandated a 25 percent statewide reduction in water use (relative to 2013 levels) by urban water suppliers. The more than 400 public water agencies affected by the regulation were also required to report monthly progress towards the conservation goal to the State Water Resources Control Board. The electricity savings associated with the water conservation were approximately 156% of the total first-year electricity savings secured by the investor-owned utilities' investments in electricity efficiency programs over roughly the same time period. In addition, the water conservation-related GHG savings represented the equivalent of taking about 149,000 cars off the road for a year. These indirect, large-scale electricity and GHG savings were achieved at costs that were competitive with existing programs that target electricity and GHG savings directly and independently. The energy and GHG savings associated with California's proposed indoor and outdoor water use efficiency standards will be further explored as part of this presentation.
  • Energy savings and GHG emission reductions associated with water conservation can be substantial
  • Investment of energy efficiency and carbon cap-and-trade funds into the water sector may accelerate the ability of, and create new opportunities for. water utilities to meet new state standards

Optimizing Wind or Solar-Power Water Desalinization

2.45 - 3.15 pm

This presentation discusses a method of integrating commercial wind turbines and solar PV arrays with Reverse Osmosis (RO) water desalinization plants to make fresh water from clean, sustainable energy. A proprietary logic controller is used to make extra fresh water when the winds are blowing strong or the sun is shining, and can store this water storage much more cost effectively that storing electricity itself. The presentation discusses pre-engineered wind/solar and RO system configurations that are being introduced for island communities, developing markets, or high energy cost regions. Key takeaways:
  • Storing water is less expensive than storing electricity
  • Special logic is required to ramp up and down RO filter stacks
  • RO plants can filter brackish or salt water into fresh water
