This document summarizes the Philadelphia Water Department's (PWD) strategic energy plan to reduce energy consumption and costs. The plan includes establishing energy use and cost baselines, identifying conservation and renewable energy projects, and prioritizing a list of initiatives. Some key initiatives are installing solar panels at the Southeast Water Pollution Control Plant, exploring biogas cogeneration at wastewater plants, and pursuing a 2-5 MW solar installation through a power purchase agreement. The plan aims to lower PWD's energy costs and greenhouse gas emissions while ensuring reliable water and wastewater services.

Abstract
Concern over the global energy system, whether driven by climate change, national security, or fears of shortage, is being discussed widely and in every arena but with a bias toward energy supply options. While demand reduction is often mentioned in passing, it is rarely a priority for implementation, whether through policy or through the search for innovation. This paper aims to draw attention to the opportunity for major reduction in energy demand, by presenting an analysis of how much of current global energy demand could be avoided. Previous work led to a “map” of global energy use that traces the flow of energy from primary sources (fuels or renewable sources), through fuel refinery, electricity generation, and end-use conversion devices, to passive systems and the delivery of final energy services (transport, illumination, and sustenance). The key passive systems are presented here and analyzed through simple engineering models with scalar equations using data based on current global practice. Physically credible options for change to key design parameters are identified and used to predict the energy savings possible for each system. The result demonstrates that 73% of global energy use could be saved by practically achievable design changes to passive systems. This reduction could be increased by further efficiency improvements in conversion devices. A list of the solutions required to achieve these savings is provided.

Utilization of Existing Generation Fleet Using Large Scale Energy Storage Sys...Tu Nguyen
In this work, we developed an optimization framework to evaluate the benefit of large-scale energy storage system (ESS) for utilizing an existing generation fleet that often operates at suboptimal working conditions due to peaky nature of the load. The objective is to find the optimal schedule for thermal units and the ESS that minimizes the daily system operating cost. Case studies are conducted to evaluate the operating cost savings by using ESSs for a utility company in Alaska.

Kadena USAF Air Base, Okinawa, Japan; Waste To Energy Feasibility StudyJeffrey Riegle
This is the finding report that our team created for the Kadena USAF Air Base, Okinawa, Japan; Waste To Energy Feasibility Study. It looked at three different technologies: Incineration, Plasma Gasification, and Anaerobic Digestion. Lots of good information, and more backup can be found in the report.
Provided technical input, peer review, environmental, and project oversight for a feasibility study to evaluate incineration, plasma gasification, and anaerobic digestion as waste to energy technologies on the island of Okinawa, Japan. Each technology was evaluated for technical feasibility with the current waste stream at KAB, potential energy generation and uses, cost and payback, and potential environmental issues.
Based on this evaluation, a Waste-to-Energy Feasibility Assessment Report was prepared for KAB. This report discusses the feasibility of each of these waste-to-energy technologies, evaluates environmental permitting issues for each technology, recommends uses for generated energy (electricity, steam, etc.), and discusses life cycle costs and payback. Recommendations were made regarding the preferred waste-to-energy technology for implementation at KAB.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Funding Infrastructure Investments with Guaranteed PerformanceSchneider Electric
Municipalities are dealing with numerous financial constraints, and trying to improve or expand systems is often trumped by maintaining deteriorating assets. Discover the potential benefits of Performance Contracting (PC). PC is an alternate delivery method to the traditional CIP process for the implementation of operational cost saving and energy saving projects. While the PC process has been used extensively in municipal buildings for decades -- primarily for HVAC and lighting improvements -- it has only recently begun to be used by water and wastewater utilities for process-centric improvements to treatment plants, pump/lift stations and other assets.
