To help our readers stay on top of energy developments, here’s a dynamic, up-to-the-minute guide to what’s trending at the ISO.


California ISO launches expanded online data resource. Today’s Outlook now offers easy access to data on electric grid and markets

The California Independent System Operator (ISO) today unveiled a major overhaul of its most-visited public web page, which provides a central location for accessing key data. The new Today’s Outlook page on the ISO website allows viewers to quickly see changing supply and demand trends, forecasted and actual peaks, energy supplies by resource type, and renewable energy production. The enhanced net load graph will now depict daily system ramps, which illustrates changes to the power supply system as it increasingly shifts to clean energy sources.

ISO posts discussion paper on future electric system

Based on the input from more than a dozen energy industry leaders and policymakers, the California ISO prepared and published “Electricity 2030 – Trends and Tasks for the Coming Years,” intended to spark discussion from many perspectives on the vision of a low-carbon, decentralized energy system. The document outlines the shifts happening in the industry today, and recommends actions to help maintain a reliable and clean grid, through the year 2030 and beyond.

Oregon’s Portland General Electric joins western Energy Imbalance Market

Oregon’s Portland General Electric on October 1, 2017 became the fifth utility to begin participating in the western Energy Imbalance Market. The EIM, which has generated costs saving of about $213 million since November 2014, now serves over 38 million consumers in eight western states. Read the news release here.

The 2017 solar eclipse

The California ISO planned for more than a year to manage challenges on the electric grid during the “Great American Eclipse” on Aug. 21, 2017, when solar production dropped, and the ISO successfully managed the reduction in sun power.

Managing energy oversupply on the green grid

Increasing amounts of renewable energy coming online creates new challenges for grid operations and the bulk electric market. Because of high levels of solar production in the middle of the day, the grid often has an oversupply of energy, and sometimes has to curtail, or scale back, renewable energy generation. As the ISO advances toward the state’s 50-percent renewable goal, find out more about oversupply, what the ISO does to mitigate it, and some of the promising options on the horizon for solving it.
