Richmond’s Community Energy and Emissions Plan (CEEP) identifies that to reach this target will require near universal adoption of zero carbon vehicles by the 2040s. The CEEP includes Strategy 7 to “Promote Low Carbon Vehicles”, and actions pursuant to this strategy. In accordance with this CEEP action, the City of Richmond recently adopted amendments to the Parking and Loading section of the Richmond Zoning Bylaw, establishing requirements for provision of electric vehicle (EV) charging infrastructure in new developments. Amendments require all residential parking, excluding visitor parking, feature an energized outlet capable of delivering Level 2 EV charging (as defined by SAE J1772 standard – i.e. 208V/240V). Intention of the requirement is to better future-proof buildings so that at-home charging is readily accessible. To assist implementation of the requirements, the City aims to issue technical bulletins that 1) describe suitable electrical configurations, and 2) provide guidance on expectations for strata rules/bylaws that owner-developers can provide for future strata organizations to facilitate successful operation of EV charging infrastructure. Other municipalities in the Province of British Columbia are similarly considering options to encourage adoption of EVs, to support climate, air-quality, economic development and livability goals. A number of municipalities have already revised policies pertaining to EV charging, and others are in the process. Pursuant to such efforts, the objective of the following report is to: Provide resources to support implementation of EV charging infrastructure in shared parking areas. To achieve the objective, the intent is to provide City of Richmond, other municipalities, developers, electrical designers, and end-users an understanding of available electric vehicle supply equipment (EVSE) solutions and identify inherent implications. Major components include: 1. Infrastructure configurations and comparisons; 2. Delivery models; 3. Variance request requirements; 4. User fee assignment and electricity cost reconciliation assessment; 5. Model strata rules/bylaws development; 6. Local government guide development. Refer to the following sections for details of configuration and delivery model descriptions and comparisons. 5979988 v3 1 Resources to Support Electric Vehicle Charging Infrastructure Implementation & Requirements 2.0 CONFIGURATIONS 2.1 General EVSE configurations include: dedicated circuits; circuit sharing: o static load management; o rotational (time-shared) load management; o dynamic load management; panel load management; dwelling panel load management; building demand load management. Refer to the following subsections and configuration table (Appendix A) for further details. 2.2 Dedicated Circuit Definition: An EVSE supplied from a dedicated branch circuit. Dedicated circuits require significant electrical system infrastructure to accommodate the electrical load and dedicated wiring to each stall. A demand factor of 100% is required, as per CSA C22.1-15. Allowance for diversity is permitted in Table 38 of CSA C22.1-18 (Appendix D), when adopted (anticipated early 2019). The configuration is versatile, as it is possible to provide 6-50R or 14-50R receptacles during building construction to allow users to purchase and install a standalone EVSE of their choice. Performance is typically higher than other configurations, as there

  • 1 MA10 Final the CARBON FOOTPRINT of SUGAR
    1 MA10_final THE CARBON FOOTPRINT OF SUGAR By P. W. REIN Professor Emeritus, Louisiana State University Consultant to Better Sugarcane Initiative United Kingdom [email protected] KEYWORDS: Carbon footprint, energy, sugarcane, sugar, ethanol Abstract Climate change is rapidly becoming a serious issue and one which will increasingly demand the attention of sugar producers. Estimation of the greenhouse gas emissions in the production of sugar, otherwise known as the carbon footprint, is an essential part of any sustainability study. A method of estimating net energy usage and greenhouse gas emissions has been developed, based initially on work done on biofuels. The calculation routine was developed for use in the Better Sugarcane Initiative standards, which focus on the sustainability of the sugarcane industry. This estimation procedure estimates primary energy requirements including both direct effects, mainly energy usage, and indirect effects, which include energy used in the production of fuels, fertilisers and chemicals. Allowance is also made for the inclusion of direct land use change effects. The estimation procedure allows for the production of molasses and/or ethanol, and for the export of power. Attention is given to the potential errors and problems in arriving at these estimates. The main problems are uncertainties in emissions from fertiliser use and the way in which emissions are allocated to co-products. The results show that the carbon footprint is most affected by sugarcane yield, sugar recovery, fertiliser usage, irrigation, cane burning and power export. A factory set up efficiently for maximum power generation can show a negative carbon footprint and, in this respect, maximum export of electric power can deliver a lower carbon footprint than maximum ethanol production.

  • Integrated Supply- and Demand-Side Energy Management for Expeditionary Environmental Control
    Integrated Supply- and Demand-Side Energy Management for Expeditionary Environmental Control E. M. Craparoa,∗, J. G. Spragueb aNaval Postgraduate School, 1411 Cunningham Road, Monterey, CA, 93943 USA bUS Navy, Stuttgart, DE Abstract This paper examines efficiencies achieved by optimal scheduling of power generation equipment and electrical loads in a hybrid smart micro-grid under conditions where load activity may be delayed or advanced with negligible impact to system performance. We model military expeditionary energy systems to analyze the performance of existing unmanaged components and estimate potential savings obtained by coordinated management of battlefield heating and cooling systems. We employ rolling horizon optimization models to examine performance under varying degrees of uncertainty about future load demand and renewable production. We propose a novel mechanism to reduce power production costs through optimal prescriptive scheduling of loads, reducing peak demand and generator peak-to-average power ratios and facilitating a persistent shift to higher fuel efficiencies. In contrast to existing methods that employ either supply-side or demand-side management, we propose intelligently coordinating both sides to achieve greater efficiency. Using sensitivity analysis, this paper quantitatively demonstrates hows grid composition, temperature band tolerance, and energy storage capabilities contribute to fuel efficiency under this approach. Keywords: Load management, smart grids, optimal scheduling, expeditionary power, generators 1. Introduction The majority of this generated electricity is used for environmental control. Analysis of USMC systems found The Department of Defense (DOD) is the largest en- air conditioners and environmental control units (ECUs) ergy consumer within the U.S. government, accounting for 1 accounted for 57% of expeditionary power demand [7].

Each of the unit may have identical or different capacities. A number of power plants can be tied together to supply the system load by means of interconnection of the generating stations. Interconnected electric power system is more reliable and convenient to operate and also offers economical operating cost . Generation unit , Transformer Unit, Converter Unit, Transmission Unit, Inverter Unit and Consumer Point. This combination of all the unit is called the overall power system units. Dr Audih 3 SYSTEM LOAD VARIATION Effects of variable load. The variable load on a power station introduces many troubles in its operation. Some of the important effects of variable load on a power station are : (i) Need of additional equipment and generation units . (ii) Increase in production cost. The variation of load on the power station with respect to time. SYSTEM LOAD From system's point of view, there are 5 broad category of loads: 1. Domestic 2. Commercial 3. Industrial 4. Agriculture 5. Others - street lights, traction. Domestic: Lights, fans, domestic appliances like heaters, refrigerators, air conditioners, mixers, ovens, small motors etc. 1. Demand factor = 0.7 to 1.0; 2. Diversity factor = 1.2 to 1.3; 3. Load factor = 0.1 to 0.15 Dr Audih 4 Generation Transmission Distribution Loads Dr Audih 5 Industrial: Small scale industries: 0-20kW Medium scale industries: 20-100kW Large scale industries: above 100kW Industrial loads need power over a longer period which remains fairly uniform throughout the day.
