Smart Grid Investments Improve Grid Reliability, Resilience, and Storm Response

October 2014

This report presents findings on smart grid improvements in outage management from three Smart Grid Investment Grant (SGIG) projects using distribution automation technologies and systems. Smart grid outage management approaches accelerated service restoration and limited the number of affected customers during major recent storms. Utilities required fewer truck rolls during restoration and used repair crews more efficiently, which reduced utility restoration costs and total outage time. Business and residential customers experienced fewer financial losses, as shorter outage time limited lost productivity, public health and safety hazards, food spoilage, and inconvenience from schedule disruptions.

Technology Solutions for Wind Integration in ERCOT - Final Technical Report Appendices Part II

October 2014

Texas has for more than a decade led all other states in the U.S. with the most wind generation capacity on the U.S. electric grid. The State recognized the value that wind energy could provide, and committed early on to build out the transmission system necessary to move power from the windy regions in West Texas to the major population centers across the state. It also signaled support for renewables on the grid by adopting an aggressive renewable portfolio standard (RPS). The joining of these conditions with favorable Federal tax credits has driven the rapid growth in Texas wind capacity since its small beginning in 2000. In addition to the major transmission grid upgrades, there have been a number of technology and policy improvements that have kept the grid reliable while adding more and more intermittent wind generation. Technology advancements such as better wind forecasting and deployment of a nodal market system have improved the grid efficiency of wind. Successful large scale wind integration into the electric grid, however, continues to pose challenges. The continuing rapid growth in wind energy calls for a number of technology additions that will be needed to reliably accommodate an expected 65% increase in future wind resources. The Center for the Commercialization of Electric Technologies (CCET) recognized this technology challenge in 2009 when it submitted an application for funding of a regional demonstration project under the Recovery Act program administered by the U.S. Department of Energy1. Under that program the administration announced the largest energy grid modernization investment in U.S. history, making available some $3.4 billion in grants to fund development of a broad range of technologies for a more efficient and reliable electric system, including the growth of renewable energy sources like wind and solar. At that time, Texas was (and still is) the nations leader in the integration of wind into the grid, and was investing heavily in the infrastructure needed to increase the viability of this important resource. To help Texas and the rest of the nation address the challenges associated with the integration of large amounts of renewables, CCET seized on the federal opportunity to undertake a multi-faceted project aimed at demonstrating the viability of new smart grid technologies to facilitate larger amounts of wind energy through better system monitoring capabilities, enhanced operator visualization, and improved load management. In early 2010, CCET was awarded a $27 million grant, half funded by the Department of Energy and half-funded by project participants. With this funding, CCET undertook the project named Discovery Across Texas which has demonstrated how existing and new technologies can better integrate wind power into the states grid. The following pages summarize the results of seven technology demonstrations that will help Texas and the nation meet this wind integration challenge.

Peak Reliability (formerly part of the Western Electricity Coordinating Council)

September 2014

Peak Reliability (Peak) and eight of its member transmission organizations deployed synchrophasor technology throughout the U.S. portion of the Western Interconnection. The project installed or upgraded 584 phasor measurement units (PMUs) (393 using WISP program funding), 77 phasor data concentrators (PDCs) (57 using WISP program funding), a wide-area communications network to support PMU data transfer, information technology infrastructure, and advanced transmission software. Together, these systems increase grid operators visibility into bulk power system conditions in near-real time, enable earlier detection of problems that threaten grid stability or cause cascading outages, and facilitate sharing of information with neighboring control areas.

ATK Launch Systems - Final Technical Report

September 2014

The purpose of the NETL Project was to develop a diverse combination of distributed renewable generation technologies and controls and demonstrate how the renewable generation could help manage substation peak demand at the ATK Promontory plant site. The Promontory plant site is located in the northwestern Utah desert approximately 25 miles west of Brigham City, Utah. The plant encompasses 20,000 acres and has over 500 buildings. The ATK Promontory plant primarily manufactures solid propellant rocket motors for both commercial and government launch systems. The original project objectives focused on distributed generation; a 100 kW (kilowatt) wind turbine, a 100 kW new technology waste heat generation unit, a 500 kW energy storage system, and an intelligent system-wide automation system to monitor and control the renewable energy devices then release the stored energy during the peak demand time. The original goal was to reduce peak demand from the electrical utility company, Rocky Mountain Power (RMP), by 3.4%. For a period of time we also sought to integrate our energy storage requirements with a flywheel storage system (500 kW) proposed for the Promontory/RMP Substation. Ultimately the flywheel storage system could not meet our project timetable, so the storage requirement was switched to a battery storage system (300 kW.) A secondary objective was to design/install a bi-directional customer/utility gateway application for real-time visibility and communications between RMP, and ATK. This objective was not achieved because of technical issues with RMP, ATK Information Technology Departments stringent requirements based on being a rocket motor manufacturing facility, and budget constraints.
