GE powers California load shifting project

Discovery Science Centre in Santa Ana houses the pilot project

GE Energy Storage is providing the storage for a 500 kWh load-shifting project for the Southern California Edison project at the Discovery Science Centre in Santa Ana.

The project aims to shift 10 – 20% of the centre’s daily electrical consumption to off-peak hours by using a 500kWh storage system to provide backup power.

GE is providing a turnkey Durathon battery energy storage system and Princeton Power Systems is providing the invertor control system to integrate with the storage system to load shift to enable the Centre to reduce its peak electricity usage and thus its electrical bill.

Kellee Preston, Vice President of operations at Discovery Science Centre, said: “We are eager to demonstrate technologies that can reduce our energy cost while adding to the reliability of the electric grid. We’ll be able to use the system to increase outreach on energy issues and better explain the benefits that storage can bring to the electric grid system.”

Southern California Edison is managing the project as part of California’s statewide initiative to reduce peak demand on the electrical grid. Along with the Centre, SCE will monitor the performance of the system and use it to assess how remote storage systems can bolster distribution network’s performance.

European Commission invests in batteries for improving grid infrastructure

The European Commission holds the purse strings for the project

A 250MW battery storage installation in Italy is included in a list of 250 projects the European Commission is investing €5.85 billion in. The battery storage systems will be connected to the critical 150 kV transmission networks in Central South Italy.

Power-One introduces first energy storage system for PV in UK

Mon, 09/30/2013 - 11:46 -- Ruth Williams
As feed-in tariffs become less rewarding, energy storage is expected to gain popularity

 

Power-One, part of the ABB Group, is introducing a residential energy storage solution for the UK market. The energy storage system, called Renewable Energy Accumulator and Conversion Technology (REACT), will be available in 2014.

It will feature a 4.6kW single-phase grid connected Power-One inverter and a 2kWh lithium-ion battery.

The system is for use with home PV panels to capitalise on energy storage as feed-in tariffs are reduced over the coming years.

"PV energy has to be available upon demand, since its feed-in to the grid is no longer worthwhile," Paolo Casini, VP of Marketing, said.

"With REACT we enable homeowners and landlords to adjust energy production and consumption with their needs, helping them to increase self-consumption and save money on their energy bills with the energy storage solution."

Award winning US storage projects

Santa Rita Jail Smart Grid project’s energy storage management system supplied by S&C Electric Company

Four projects involving a multiplicity of companies won commercial achievement awards at the Energy Storage North America (ESNA) conference in San Jose. Notrees Wind Energy Storage, SCPPA Thermal Energy Storage Programme, Santa Rita Jail Smart Grid, and Grid on Wheels each won for their innovation at utility scale.

The first project to win was the Notrees Wind Energy Storage Project, located in Goldsmith, TX. It performs frequency regulation, renewables capacity firming and electricity shifting with a 36MW, 24MWh advanced lead-acid storage system. Xtreme Power, Duke Energy and the DOE won an utility-scale awards for this project.

The second award went to Southern California Public Power Authority (SCPPA) Thermal Energy Storage Programme located in Glendora, CA. It uses thermal energy installed at 200 customer facilities, totaling 2.5MW, 15MWh of rated capacity to supply energy time shifting, T&D deferral and renewable energy time shifting to the grid. SCPPA and Ice Energy also won a utility scale award for this project.

Next up was the Santa Rita Jail Smart Grid, in Dublin, CA, which is the country's largest CERTS-based microgrid (Consortium for Electric Reliability Technology Solutions) with renewable generation and large-scale energy storage. The microgrid remains operational even in the event of a regional power outage to maintain reliability and security at Alameda County's Santa Rita Jail. The companies involved were Alameda County, APT, BYD, CEC, Chevron Energy Solutions, DOE, Encorp and S&C Electric.

The final project to win was Grid on Wheels, of Newark, DE. It is the first case of EV batteries, chargers, and charging infrastructure to participate in, and generate revenue from, open ancillary services markets, including frequency regulation. The companies involved, BMW, EV Grid, NRG, and University of Delaware, won the award for being the most innovative mobility project in North America.

Entrants came from a range of applications that generate revenue by providing market services for the grid, such as frequency regulation, load shifting or spinning reserve. They were marked for: services provided to the grid, financing options, ownership model and technology strengths.

California becomes first state to introduce energy storage targets

Thu, 09/05/2013 - 16:54 -- Ruth Williams
Welcome to Cali

The California Public Utilities Commission (CPUC) has authored a proposed decision to install 1.325GW of energy storage across the state by 2020. Commissioner Carla Peterman has set out year-by-year procurement targets for Southern California Edison (SCE), San Diego Gas & Electric (SDG&E) and Pacific Gas & Electric (PG&E).

The installed energy storage can come from any type of technology and can be employed for a variety of functions such as capacity, ancillary services and peak shaving.

PG&E and SCE are each required to install 580 MW of capacity and SDG&E must acquire 165 MW in total by 2020. The utilities would be allowed to own some of the energy storage capacity as part of their distribution system planning process.

This is the first time energy storage has been included in a State policy, supporters hope it will create a market for electrical energy storage solutions. There has been opposition to the proposal from stakeholders, including generator set trade representatives, who believe electricity storage suppliers should compete in the capacity market with other technologies rather than being prioritised in such a way.

The first installations of capacity must be no later than December 2014.

South Korea battery exports reach new high

Mon, 07/23/2012 - 18:02 -- Ruth Williams

South Korea shipped 20% more rechargeable batteries overseas in 2011 finacial year than the previous year.  Of these, 56% were lithium-ion making South Korea the world’s largest exporter of lithium-ion batteries for 2011.  The exports of the batteries were valued at US$3.8 billion according to the Korea Customs Service.
