The Benefits of Trunking SIP

A SIP trunk is a logical connection from one point to another via the Internet. It makes use of Session Initiation Protocol (SIP) to set up communication between two parties, i.e. a customer and an Internet telephony service provider (ITSP) over the internet. This call is then transferred to the÷ Public Switched Telephone Network (PSTN). As the entire process takes place over the internet, need for physical wires required for traditional telephony is eliminated.

Lithium-ion deal plugs batteries into U.S. grid

AES said it will use 20 MW of the batteries to regulate frequency on the New York grid, the same kind of application needed to back up giant wind and solar farms. In addition, AES"s corporate parent said it will use lithium ion starting in 2011 as back up for a 32 MW wind plant it operates in West Virginia. dell inspiron 1525 battery

"We wouldn"t be doing projects at this scale if there was still product development" needed in the technology, Chris Shelton, president of AES Energy Storage, said in an interview.

He would not reveal financial details of the A123 purchase. However, he did say part of the New York plan depends on closing loan guarantees with the U.S. Department of Energy.

AES has operated since December 2009 a 12 MW energy storage system installed by A123 at one of its power plants in Chile. That system is based on battery technology A123 developed for a hybrid bus for BAE Systems, Shelton said. dell latitude d610 battery

Although the technology for grid-scale lithium ion storage is ready, the regulations and financial incentives are not, Shelton said.

Congress is debating investment tax credits for buying grid-scale lithium ion batteries. Regulators are discussing pay-for-performance metrics that would let companies like AES charge a premium over competing power plants because they can supply energy faster and with greater precision.

Regulators also need to hammer out ways to enable risk-averse utilities to acquire new technologies such as lithium ion, something utilities are reluctant to do that with rate payer"s money today. AES is negotiating deals to resell A123"s battery systems to electric utilities, but so far it has only installed the systems at its own power generation plants.
