Eaton UPS products receive US Energy Star rating

Wed, 01/09/2013 - 17:36 -- Ruth Williams

Eaton’s 5P, 5PX and 9PX UPS systems are Energy Star qualified following stringent third-party testing and verification of meeting the United States’ energy efficiency requirements.

Energy Star is a joint programme established by the US Environmental Protection Agency and the US Department of Energy intended to help consumers save money and protect the environment through energy efficient products and practices.

According to Energy Star, if all UPSs sold in the US in 2012 meet the Energy Star requirements, the energy cost savings will grow to $471m and prevent greenhouse gas emissions equivalent to the emissions from more than 636,000 vehicles.

Following the qualification, Eaton said it now offers the largest selection of Energy Star for server, storage and network protection applications. Eaton said it plans to continue the Energy Star certification process for additional UPS products.

KiWi Power to partner UK Power Networks in 10 MWh energy storage project

Tue, 12/04/2012 - 17:36 -- Ruth Williams

Demand response provider KiWi Power is to partner distribution company UK Power Networks in developing a 10 MWh energy storage system with lithium-ion batteries.

Installation of the facility at a trial site in Bedfordshire will commence in January 2013. The energy storage device comprises a 10 MWh lithium-ion battery system with racks of battery cells, 6 MW power conversion system (PCS) with 11 kV step-up transformer and 11 kV switchgear and protection.

KiWi Power will manage the commercial arrangements for the energy storage unit's participation in National Grid's load balancing services, including short-term operating reserves (STOR) and frequency response.

The Smarter Network Storage (SNS) project is one of five schemesDemand Management selected by UK energy regulator Ofgem to help secure electricity supply and develop a new smart grid network. The four-year project which will examine the technical challenges and commercial opportunities of using stored electricity to meet peak energy demands and investigate the financial benefits of deferring or avoiding network reinforcement and selling flexibility services.

Yoav Zingher, CEO of Kiwi Power said: “Alongside demand side response measures, energy storage has the flexibility to meet increasing demand peaks and help to manage the supply-side energy provision from intermittent wind and inflexible nuclear energy. This trial is an important step towards proving the benefits of energy storage and will provide essential information for understanding the practicalities and economics of energy storage ahead of a smart grid transition.”

The five schemes received £45.5m ($73.3m) second-tier funding through Ofgem’s Low Carbon Networks (LCN) fund. Once the project has proven successful and the capabilities of energy storage are fully understood, it is expected that similar projects could be rolled out across the UK and provide savings of over £700m by 2040. 

Saft powering Canadian wind turbine

Mon, 11/19/2012 - 17:36 -- Ruth Williams

The energy storage system will include two large-scale lithium-ion battery packs to store energy generated by wind power from an 800kW wind turbine.

The harnessed energy will be fed back to the electrical grid to be used during peak times of energy consumption, with the battery being recharged during off-peak periods.

Saft has demonstrated that this base system achieves a maximum ramp rate of 10% per minute of the rated power output of the 800kW wind turbine while also providing up to 400kWh of peak shaving capability. The flexibility and scalability of Saft's solution also allows the energy content to be increased in 124kWh increments up to 992kWh if additional peak shaving capability is desired.

This is the first project of its kind that Saft is involved in in North America.
