First-of-a-Kind Interactive Tool Drills Down to the County Level

With a few clicks of a mouse, it’s now easy to see the differences across the country when it comes to the cost and affordability of electricity. Users can sort and compare nearly 100 residential customer affordability metrics or variables and also zoom in to get information by individual counties. 

This color-coded, visual representation with an easy-to-use interface was developed by researchers at PNNL. The tool is based on publicly available household income information from census data combined with utility revenue and customer count information from the federal Energy Information Agency. Together they determine a customer “cost burden” for electricity.

Hawaii Makes First Move for Grid Frequency-Watt Control, May 4, 2018

In February 2018, Hawaiian Electric became the first U.S. utility to require system-wide activation of frequency-watt control, following the recommendations of a July 2017 GMLC Technical Report

Interoperability Roadmap Methodology Published, March 28, 2018

This roadmap methodology is to be applied to technology integration ecosystems (e.g., electric vehicles, photovoltaic inverters, or automated buildings), using tools that measure the state of interoperability today, to identify the gaps and challenges that can be overcome to improve interoperability, and thereby, simplify the integration process.

Peer Review Report Published, January 25, 2018

In April 2017, the U.S. Department of Energy’s (DOE’s) Grid Modernization Initiative (GMI) conducted its first external peer review of the projects awarded to the GMLC to execute a diverse portfolio of technologies to modernize the nation’s grid. Results from this review are now available. For more information and the report, see the DOE website.

Training for Regional Distribution Systems Planning Starts in New England, October 26, 2017

To help regulators keep on top of changes in technologies and best practices in distribution system planning, Berkeley Lab, in partnership with the National Renewable Energy Laboratory, Pacific Northwest National Laboratory, and the National Association of Regulatory Utility Commissioners (NARUC), led the first in a series of regional training sessions on September 27–29 at the Maine Public Utilities Commission in Portland, Maine. Approximately 40 public utility commissioners and staff from the six New England states attended the training to inform their ongoing grid modernization efforts related to distribution system planning, grid modernization investment plans, distributed energy storage, and transportation electrification.

New Grid Modernization Projects Announced for Resilient Distribution Systems , September 27, 2017

The Department of Energy recently announced seven new National Laboratory-led projects to develop and validate innovative approaches for grid resiliency. As part of the department’s Grid Modernization Initiative, the projects focus on the integration of clean distributed energy resources (DER), advanced controls, grid architecture and emerging grid technologies at a regional scale. Coordinated through the Grid Modernization Laboratory Consortium in collaboration with both public and private partners, the projects are expected to deliver credible information on technical and economic viability of the solutions, as well as demonstrate viability to key stakeholders who are ultimately responsible for approving and investing in grid modernization activities. 

Energy Storage Battery Energized in Chattanooga, September 22, 2017

Stakeholders gathered at the Solar Share community solar array in Chattanooga, Tennessee, as the city’s Electric Power Board utility energized a new 100kW/400kWh Vanadium Redox Flow Battery that will be used for a wide variety of power grid integration and energy management applications. This accomplishment is part of national research efforts to explore the best use of cutting edge technologies that could be implemented across the United States to modernize the power grid.   

Dynamic Contingency Analysis for Cascading Failures, September 1, 2016

The Dynamic Contingency Analysis Tool, or DCAT, uses cascading failure analyses to screen for weak spots on the grid, evolving beyond previous “steady-state contingency analysis” tools to “dynamic analysis” to simulate the sequences of cascading outages.

Mode Meter: Keeping Oscillations in Check, September 1, 2016

Researchers at PNNL joined with colleagues at Montana Tech and the University of Wyoming to develop Mode Meter. This software uses data from advanced sensors—called synchrophasors— placed on power lines and other electrical transmission devices to obtain precise, time-synchronized data about power grid operation.

New Inverter Testing Supports Solar in Hawaii, September 1, 2016

NREL partnered with SolarCity and the DOE Solar Energy Technology Office to quantify the impacts of ground fault and load rejection overvoltage in Hawaii.

NREL + Duke Energy Test Voltage Control for Distributed Solar, September 1, 2016

NREL and partner GE Grid Solutions simulated future circuit operations with a distribution management system provided by Duke, comparing three operating modes: with conventional inverters; with advanced inverters providing local power control; and with advanced inverters coordinated by the DMS to optimize voltage control.

Outsmarting Storms in Chattanooga, September 1, 2016

Through a DOE Smart Grid Investment Grant, the Electric Power Board of Chattanooga secured funding to accelerate the modernization of their power infrastructure.
