The California Public Utilities Commission (CPUC) unanimously approved a decision ordering Southern California Edison (SCE) to procure between 1,400 and 1,800 MW of energy capacity in the Los Angeles basin to meet long-term local requirements by 2021. Of this amount, at least 50 MW is required by the CPUC to be procured by SCE from energy storage resources, as well as up to an additional total of 600 MW of capacity required to be procured from preferred resources – including energy storage. “Preferred resources” also include e
Sempra U.S. Gas & Power, BP Wind Energy and community leaders dedicated the new Auwahi wind facility on Ulupalakua Ranch in Hawaii. The 21-MW Auwahi Wind facility is BP and Sempra’s first alternative energy venture in Hawaii. The project features a 4.4-MWh grid battery system, which at its peak, can sustain 11 MW of capacity for approximately 25 minutes. The battery system helps regulate and sustain power to Maui Electric Co.’s grid during light wind conditions.
CALMAC is now a member of the Texas Energy Storage Alliance (TESA), a technology-neutral coalition of energy storage technology product and service companies. By joining the Alliance, CALMAC will address summer peak energy demands and provide knowledge of thermal energy storage for reducing a buildings peak energy load.
Duke Energy Renewables, part of Duke Energy's Commercial Businesses, completed its 36-MW energy storage and power management system at its Notrees Windpower Project in west Texas. The system completed testing and became fully operational in December 2012. Xtreme Power designed and installed the 36-MW capacity Dynamic Power Resource at Notrees and will continue to operate the system.
Technology is quickly making energy storage more economical and effective than ever before. But companies that wish to invest in storage capacity face a journey through a frustrating regulatory no-man’s land. Opening the gateway for storage to deliver smart grid benefits will require a more streamlined and coherent approach to regulating storage as utility infrastructure.
The goal of implementing a distribution management system (DMS) is to upgrade isolated, hands-on grid management processes into an interconnected and automated platform. This technology is transforming the way utilities operate distribution networks, and setting the industry on a path toward seamless integration of distributed resources—both supply and demand.
Green energy mandates might overburden gas pipelines.
By Diane A. Rigos, Boris L. Shapiro and Richard L. Levitan
Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.
Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.
Opportunity for advancement or exercise in futility?
The power grid has been slow to embrace renewable energy sources. In order to allow renewable energy sources to evolve into a solution rather than a headache, new tools and processes will need to be developed to forecast and control renewable production capabilities.
