Energy Sustainability

The Water Environment Federation (WEF) and industry leaders have identified the need for an energy roadmap to guide utilities of all sizes down the road to overall sustainable energy management through increased renewable energy production and energy conservation. This roadmap leverages a framework developed by the electric power sector. Known as the The Smart Grid Maturity Model (SGMM), the framework moved the industry toward “Smart Grid” technology. The basis of the Energy Roadmap originated at a workshop of water and power industry leaders convened by WEF in North Carolina in March 2012. Case studies were analyzed from successful utilities in Austria, Holland, Australia, and the United States. High level, strategic best practices were identified and organized into topic areas, which define the level of progression (enable, integrate and optimize) towards achieving energy sustainability. As a living document, the roadmap is always under review by dedicated groups within the industry. A number of utilities worldwide have already taken the leap and begun this transformation towards resource recovery and many more are peering over the edge. The WEF Energy Roadmap is intended to guide utilities of all sizes as they progress toward becoming treatment plants of the future. While it is not practical for all wastewater treatment plants to become energy positive or neutral, all can take steps towards increasing energy sustainability. A key component of the WEF Energy Roadmap is collaboration between water/wastewater utilities and electric utilities. This paper focuses on lessons learned and case studies about energy and water utilities working together to address energy-water nexus challenges. This paper examines perspectives both from energy use at water sector facilities and water use at energy sector facilities.

Energy And Climate Policy

Managing energy use by municipalities should be an important part of local energy and climate policy. The ISO 50001 standard constitutes an internationally recognized catalogue of requirements for systematic energy management. Currently, this standard is mostly implemented by companies. Our study presents an approach where consultants supported 28 European municipalities in establishing energy management systems. A majority (71%) of these municipalities had achieved ISO 50001 certification by the end of our study. We also conducted two surveys to learn more about motivations and challenges when it comes to establishing municipal energy management systems. We found that organizational challenges and resource constraints were the most important topics in this regard. Based on the experiences in our study we present lessons learned regarding supporting municipalities in establishing energy management systems.

The chapter describes a dynamic smart grid concept that enables electricity end-users to be acting on controlling, shifting, or curtailing own demand to avoid peak-demand conditions according to information received about electricity market conditions over the Internet. Computer-controlled switches are used to give users the ability to control and curtail demand on a user’s premises as necessary, following a preset user’s preferences. The computerized switching provides the ability to accommodate local renewable energy sources as available. The concept offers further the ability to integrate charging electrical vehicles during off-peak periods, helping thus substantially improving the utilization of the whole electricity system. The approach is pursuing improved use of electrical energy associated with improved energy management, reduced electricity prices and reduced pollution caused by excessive use of combustion engine in transport. The technique is inherently restricted to take effect in frame of energy tariff regimes based on real-time price made to encourage and reward conscious users being proactively participating in holistic energy management strategies.

The United States Chemical Safety & Hazard Investigation Board (CSB) was conceived by Congress following a series of catastrophic industrial accidents in the mid to late 1980s. This federal agency is charged with investigating incidents at chemical and manufacturing facilities, determining the causes, and making recommendations to prevent future accidents. This paper focuses on the findings from several CSB investigations related to equipment failure. Numerous codes, standards, and good practice guidelines are in place to govern the design, maintenance, and operation of vessels. However, the CSB has found that serious accidents continue to occur because of poor implementation of established guidance. This paper uses actual case studies to illustrate problems with equipment that ultimately led to catastrophes. Lessons learned from these incidents include designing equipment with adequate overpressure protection, adjusting inspection frequencies based on actual observations, and requiring written procedures for critical phases such as startup. Additional good practices and recommendations from the CSB are discussed with each of the case studies.

Since the 1990s, the field of smart grid has attempted to remedy some of the core development deficiencies associated with power supply in the smart city. While it seemingly succeeds in provision of electricity, it fails to fully resolve the difficulties associated with sustainable energy consumption. This suggests that the future of smart grid analytics in the smart city largely depends on efficiency in energy consumption which integrates sustainability in the overall energy use. This chapter analyzes the nexus between smart grid, sustainable energy consumption, and the smart city.

As part of the process of renewing the operating license for an additional 20 years after the original 40-year design life, nuclear plant owners in the United States (US) are required to show that they are managing the effects of aging of systems, structures, and components. US Nuclear Regulatory Commission (NRC) report NUREG-1801, the “Generic Aging Lessons Learned (GALL) Report,” identifies acceptable aging management programs, including programs for fatigue and cyclic operation. This includes fatigue usage analyses that account for reduced fatigue life for components in a reactor water environment. Earlier revisions of the GALL report required plants to perform environmentally-assisted fatigue (EAF) analyses using the rules in reports NUREG/CR-6583 (for carbon and low alloy steels) and NUREG/CR-5704 (for austenitic stainless steels), which were developed in 1998 and 1999, respectively. However, GALL Revision 2, issued in December 2010, requires that the rules in NUREG/CR-6909, issued in 2007, be used for nickel alloy materials, and allows it to be used for carbon, low-alloy and stainless steels as an alternative to those in the previous reports. This paper presents an application of the NUREG/CR-6909 rules, and makes several observations about the differences between using the newer and older rules. The analyses presented were performed for a sample set of boiling water reactor (BWR) locations.

Travel by rail in the United States is one of the safest modes of transportation available. On the rare occasion that major accidents do occur, they represent an opportunity for railroads to learn what has happened and what needs to be done to prevent reoccurrence. This paper provides several, detailed case studies of noteworthy passenger and rail transit accidents that have occurred in the United States, from the 1960s to the present. It discusses the outcome of these accidents, including changes that were implemented due to lessons learned. It also discusses unique and/or noteworthy aspects of each accident.

Restoration Effort

In the United States, extensive investments have been made to restore the ecological function and services of coastal marine habitats. Despite a growing body of science supporting coastal restoration, few studies have addressed the suite of societally enabling conditions that helped facilitate successful restoration and recovery efforts that occurred at meaningful ecological (i.e., ecosystem) scales, and where restoration efforts were sustained for longer (i.e., several years to decades) periods. Here, we examined three case studies involving large-scale and long-term restoration efforts including the seagrass restoration effort in Tampa Bay, Florida, the oyster restoration effort in the Chesapeake Bay in Maryland and Virginia, and the tidal marsh restoration effort in San Francisco Bay, California. The ecological systems and the specifics of the ecological restoration were not the focus of our study. Rather, we focused on the underlying social and political contexts of each case study and found common themes of the factors of restoration which appear to be important for maintaining support for large-scale restoration efforts. Four critical elements for sustaining public and/or political support for large-scale restoration include: (1) resources should be invested in building public support prior to significant investments into ecological restoration; (2) building political support provides a level of significance to the recovery planning efforts and creates motivation to set and achieve meaningful recovery goals; (3) recovery plans need to be science-based with clear, measurable goals that resonate with the public; and (4) the accountability of progress toward reaching goals needs to be communicated frequently and in a way that the general public comprehends. These conclusions may help other communities move away from repetitive, single, and seemingly unconnected restoration projects towards more large-scale, bigger impact, and coordinated restoration efforts.
