  • Renewable Energy Generator Output – Sample Calculations
    Net Metering Program Highlights Net metering will be available to new customers until the size of the program reaches 1% of the electric provider’s previous year system peak in MW. The 1% will be measured against the total of the generator nameplate capacities for all participating customer’s generators and is split into the following tiers: (1) 0.5% for ≤ 20 kW True Net Metering This tier will include almost all residential customers. • Billing is based on net usage. • Customer receives the full retail rate for all excess kWh. • Utility shall use the customer’s existing meter if it is capable of reverse registration (spinning backwards) or install an upgraded meter at no additional cost to the net metering customer. • Utilities with fewer than 1,000,000 customers shall charge net metering customers at cost for an upgraded meter if the customer’s existing meter is not capable of reverse registration (spinning backwards). • A generator meter shall be provided at cost, if requested by the customer. (The generator meter is for the customer’s benefit. Utilities are not obligated to read a customer’s generator meter.) • No interconnection costs (beyond the combined $100 interconnection/net metering application fees), study fees, testing or inspection charges. • Net metering credits carry forward indefinitely. (2) 0.25% for >20 kW up to 150 kW Modified Net Metering • Customers pay full retail rate for electricity deliveries from the utility and receive the generation portion of the retail rate or a wholesale rate for deliveries to the grid. • No charge for the engineering review. • Customers pay all interconnection costs, distribution study fees and any network upgrade costs.

  • Electric Transmission and Distribution Equipment Use
    Electric Transmission and Distribution Equipment Use Final Rule: Mandatory Reporting of Greenhouse Gases (40 CFR 98, Subpart DD) Under the final Mandatory Reporting Rule for Additional Sources of Fluorinated Greenhouse Gases (GHGs), owners and operators of electric power system facilities with a total nameplate capacity that exceeds 17,820 lbs (7,838 kg) of sulfur hexafluoride (SF6) and/or perfluorocarbons (PFCs) must report emissions of SF6 and/or PFCs from the use of electrical transmission and distribution equipment. Owners or operators must collect emissions data, calculate GHG emissions, and follow the specified procedures for quality assurance, missing data, recordkeeping, and reporting. How Is This Source Category Defined? The electrical transmission and distribution equipment use source category consists of all electric transmission and distribution equipment and servicing inventory insulated with or containing SF6 or PFCs used within an electric power system. This equipment includes but is not limited to gas-insulated substations; circuit breakers; switchgear, including closed-pressure and hermatically sealed-pressure switchgear; gas-insulated lines containing SF6 or PFCs; gas containers such as pressurized cylinders; gas carts; electric power transformers; and other containers of SF6 or PFC. For the purposes of this subpart, facility is defined as the electric power system, comprising all electric transmission and distribution equipment insulated with or containing SF6 or PFCs that is linked through electric power transmission

  • Demand Side Management Effects on Substation Transformer Capacity
    applied sciences Article Demand Side Management Effects on Substation Transformer Capacity Limits Kerry D. McBee, Jacquelyn Chong and Prasanth Rudraraju * Department of Electrical and Computer Engineering, California State University, Fresno, CA 93740, USA * Correspondence: [email protected] Received: 24 June 2019; Accepted: 7 August 2019; Published: 9 August 2019 Featured Application: The research provides insight into the effects that high penetrations of photovoltaic (PV) systems, energy storage (ES) applications, and electric vehicle (EV) charging systems will have on substation transformer capacity ratings. The manuscript identifies how these applications change the operational conditions of a transformer to the point where capacity ratings (normal and emergency) should be adjusted to account for the additional internal heating in the windings and oil. The research also identifies how harmonic distortion induced by PV, ES, and EV charging equipment affects capacity ratings. The results of the analysis are utilized to describe mitigating approaches for existing units and new units being designed. The approaches are applied to the design attributes of a 50 MVA SPX Waukesha transformer. Abstract: In high penetrations, demand side management (DMS) applications augment a substation power transformer’s load profile, which can ultimately affect the unit’s capacity limits. Energy storage (ES) applications reduce the evening peaking demand, while time-of-use rates incentivize end-users to charge electric vehicles overnight. The daily load profile is further augmented by high penetrations of photovoltaic (PV) systems, which reduce the midday demand. The resulting load profile exhibits a more flattened characteristic when compared to the historical cyclic profile. Although the initial impact of PV and ES applications may reduce a unit’s peak demand, long-term system planning and emergency conditions may require operation near or above the nameplate rating.
