PNM, an energy holding company based in Albuquerque, N.M., is moving forward on a smart grid energy storage demonstration project that involves the installation of a utility scale battery and 500 kilowatt solar photovoltaic plant. The project was recently approved by the N.M. public regulatory commission. PNM is New Mexico's largest utility.
The goal of the "Prosperity Energy Storage" project is to create a firm, dispatchable, distributed renewable generation resource, says Steve Willard, project manager.
The project, which received more than $2 million from the DoE, is a collaborative effort between PNM, the University of New Mexico, Northern New Mexico College and Sandia National Labs. In addition to developing storage applications for solar PV, the project funds New Mexico based research, helping to move New Mexico to the forefront of national renewable energy research.
UNM will conduct system modeling and design development for the project. Northern New Mexico College will perform data collection, analysis and management. Sandia National Labs will perform system testing and algorithm development.
The project will also complement the efforts of two other PNM projects: the smart grid demonstration project with the Electric Power Research Institute and the Japanese New Energy and Industrial Technology Development Organization project at Mesa del Sol.
This blog is focused on trends in battery technology and other types of energy storage that are used for smart grid load leveling and stabilization, and as back-up power for renewable energy sources such as photovoltaics/solar power, hydro and wind energy. Trends in lithium ion batteries, lead-acid, metal-air, NaS (sodium sulfur), ZnBr (zinc-bromine) batteries will be covered, as well as compressed air energy storage (CAES), flywheels, fuel cells and supercapacitors.

ReplyDeleteThe reason is that that motorcycle batteries tend to use their charge quite easily. If you would like your battery to take care of its charge, then you'll got to recharge it on a daily basis.
