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.

 

Using Renewables to Operate a Low-Carbon Grid

Test results show renewables can offer reliability, creating a path to a greener grid. The testing, conducted in August 2016, demonstrated that renewable energy plants with smart inverter-based technology can offer electric reliability services similar, or in some cases superior to, conventional resources. This capability allows for improved grid reliability while putting more renewables on the system.

Greenhouse Gas Emissions Tracking

The ISO developed a new report to track greenhouse gas emissions from resources in the ISO balancing area, imports serving ISO load - including dynamic imports - and transfers from western Energy Imbalance Market entities serving ISO load.

Energy Imbalance Market

Grids operating across the West now have a way to share energy reserves and renewable energy reliably and efficiently through the ISO’s real-time energy market. The ISO has opened its advanced market systems to our neighbors to automatically balance supply and demand for electricity, dispatching the least-cost resources every five minutes.

Benefits of Regional Integration

Regional integration would better use resources, especially renewables, to reduce greenhouse gas emissions and costs. Enabling the ISO’s sophisticated market and grid optimization systems to pick the lowest cost energy to serve demand and give preference to renewable resources across a wide geographic region also means grid planners can build a cleaner, more resilient energy generation and delivery network that will create tangible economic benefits. 

Senate Bill 350 - Clean Energy and Pollution Reduction Act
Study results indicate that a multi-state, regional electric market would provide environmental and economic benefits to California and the West, and yield significant cost savings to the state’s electricity ratepayers.

Aliso Canyon Action Plan for Local Energy Reliability for Winter 2016-2017

The California Energy Commission, California Public Utilities Commission, California Independent System Operator, and the Los Angeles Department of Water and Power have jointly published an action plan to manage the power grid during the upcoming winter months to minimize the impacts from the use limitations imposed on the Aliso Canyon natural gas storage facility. The plan calls for extending most of the mitigation steps developed in the summer action plan.

2015-2016 Transmission Plan

In an effort to improve grid reliability, the California Independent System Operator (ISO) Board of Governors approved the 2015-2016 Transmission Plan, which calls for the construction of 13 projects at a total estimated cost of $288 million.
