The U.S. Environmental Protection Agency’s (EPA’s) plan to regulate carbon emissions is just the latest challenge facing the U.S. electric power system. Technological innovation is disrupting old ways of doing business and accelerating grid modernization. Earlier this year, AEE released Advanced Energy Technologies for Greenhouse Gas Reduction, a report detailing the use, application, and benefits of 40 specific advanced energy technologies and services. This post is one in a series drawn from the technology profiles within that report.

Several technologies can be used to store energy on the electricity transmission and distribution grid, including pumped storage hydro (PSH), compressed air energy storage (CAES), electrochemical batteries, flywheel systems and thermal energy storage systems. Electricity is then generated during peak hours by releasing the water through a hydro turbine. CAES stores energy by using an electric motor to drive an air compressor that fills a storage facility (typically an underground cavern) with compressed air.

ElectricVehicles

Plug-in electric vehicles (PEVs) are emerging as an important vehicle platform in the United States and globally. PEVs are powered completely or in part by rechargeable batteries. PEVs include battery electric vehicles (BEVs) such as the Nissan Leaf and Tesla Model S, which need to be recharged through external power sources, and plug-in hybrid vehicles (PHEVs) such as the Chevy Volt and Toyota Prius Plug-in, which contain both a battery and a gasoline-powered engine. BEVs typically have ranges of about 100 to 250 miles, while PHEVs have electric-only ranges of about 20-40 miles, after which they operate on gasoline like regular hybrid vehicles.

DistributionAutomationandNetworkEfficiency

In recent years, many transmission networks have been upgraded with new sensors and automated control equipment, which allow for more efficient centralized control. Distribution networks, however, are further behind in deploying these systems, which could improve system operations. Distribution automation technology includes a combination of line sensors, new control equipment, and intelligent software that constantly optimizes distribution system operations for reliability and efficiency.

A smart meter is an electrical device that records consumption of electricity in time intervals of an hour or less, typically 15 minutes. The meter communicates this information, along with data on power outages and quality, to utilities for monitoring and billing purposes, typically over a secure communication network.

Anaerobic_Digestion

Anaerobic digestion (AD), is a process by which waste, such as livestock manure, food scraps, and municipal/industrial wastewater, is broken down by microorganisms in the absence of oxygen into a combination of methane and other gases, otherwise known as biogas.
