APR Energy expands with new contracts

Mon, 01/28/2013 - 17:36 -- Ruth Williams

APR Energy is supplying modularised power to Guatemala, Indonesia and Senegal as part of a 101MW expansion for 2013 that sees the company investing US$150 million in rental power. This large investment is to make operational improvements and increase the use of its diesel power fleet.

The project in Guatemala is providing energy to a silver mine 40km outside of Guatemala City. The plant will be the sole power source for the mine, which is not connected to the local grid. This adds to APR’s contracts with mining companies, with projects in Mozambique and Botswana also underway.

Existing contracts with Senegal and Gabon have been extended, increasing APR’s energy supply in Western Africa by 70MW.

In Indonesia a 15MW diesel-fired power plant feeds back to the state grid system to balance the supply-demand load issues. Laurence Anderson, President and COO of APR said the project offered APR an entry to one of the largest temporary power markets in the world.

“I feel strongly that the new contracts in Indonesia and Guatemala, along with the current contract extensions, are further evidence of our continued customer satisfaction and the overall strength of the market,” said John Campion, APR Energy Chief Executive Officer. “The 101MW in January follow on the heels of the 200MW contract award and 100MW renewal in Uruguay in December and show an unmistakable momentum in our business.”

Smart grid trialled in Massachusetts

Fri, 01/25/2013 - 17:36 -- Ruth Williams

A smart grid pilot project is to be implemented in Worcester, Massachusetts, US by the National Grid to demonstrate the uses of available technology to improve energy efficiency.

Its aim is to provide energy customers with choice and control over the energy they use to empower customers to save energy, while increasing electric service reliability and improving response to power outages.

National Grid has amassed a team of experts to work on the project to construct and deliver an end-to-end smart grid pilot including smart meters, advanced communications technologies, in-home energy management tools, devices for electric system automation, as well as customer outreach and education, project management, integration and evaluation.

Unlike other smart grid trials in the US, customer engagement is key. Customers choose their level of involvement and can receive information about their energy use via the website and downloadable app. Pricing options will be available so customers can save energy and money at different times of day.

National Grid will also be researching the option of full integration of renewable energy sources, installing EV charging stations and connecting energy storage to existing renewable projects.

Duke Energy, Xtreme Power inaugurate 36 MW battery energy storage project in Texas

Fri, 01/25/2013 - 17:36 -- Ruth Williams

US power utility giant Duke Energy and energy storage provider Xtreme Power have commenced operations at the Notrees Energy Storage unit, a 36 MW battery system integrated in a 153 MW wind farm in western Texas.

wind farm

The facility at Notrees provides flexible capacity to the Electric Reliability Council Of Texas (ERCOT), which operates the electrical grid in Texas and manages 75% of the deregulated market in the state. Xtreme Power’s control system, XACT, will manage real-time performance and response of the system in response to site and grid conditions.

The US Department of Energy (DOE) provided Duke Energy with a $22 million grant to develop the project. The US Electric Power Research Institute will collect performance data from the battery storage system and help assess the potential for broader adoption of energy storage solutions throughout the industry.

Results from the storage project at Notrees wind farm will be shared publically via the DOE.


California utilities to adopt open demand response technology standard

Wed, 01/23/2013 - 17:36 -- Ruth Williams

The US OpenADR (Open Automated Demand Response) Alliance, has announced that Californian investor-owned utilities will require the OpenADR 2.0 smart grid standard for new customers in their demand response (DR) enabling technology programmes in 2013.

ADR Alliance

Pacific Gas & Electric Co. (PG&E), San Diego Gas & Electric Co. and Southern California Edison will add OpenADR 2.0 certified products to support locational dispatch of emergency and price DR resources that allow them to manage peak demand better without the need for expensive new power plants.

OpenADR is an open global standard that enables electricity providers and system operators to automatically communicate DR signals with one another and their customers by using a common language over any existing Internet Protocol-based communications network. OpenADR standardises DR price and reliability messages that automate and simplify customer DR participation and improve DR event results.

"The availability of products' complying with the OpenADR 2.0 standard will allow us to reduce the cost and improve the performance of our AutoDR programmes," said Albert Chiu, PG&E product manager. "Using an OpenADR-based system, our customers can better manage their energy use during DR events, and the utility can minimise stranded assets at the same time. The automated system has provided PG&E and our customers a better way to manage DR resources."


Himoinsa Power Systems takes aim at rental market with new gensets

Wed, 01/23/2013 - 17:36 -- Ruth Williams

Spanish genset OEM Himoinsa Power Systems has launched a 500 kW standby genset in a 10 feet-long container.


In a statement, Himoinsa said the main feature of this generator set is its size. Aimed at the rental market, the 10 feet-long container makes the 500 kW genset available in locations where a 20 feet container is not an option. 

The Spanish firm says it will launch Middle East Electricity MEE, from February 17th to 19th, a dual frequency (50/60 Hz) containerised HRTW 1300 genset, aimed at the rental market. A spokesman for Himoinsa said: “The HRTW 1300 is thought to satisfy the needs of the rental and building market and heavy duty applications.

“It has several important advantages in comparison with other sort of products operating in this segment. Among its elements, there are a variable speed fan, to reduce the fuel consumption and sound emission, and an inside lighting system, to guarantee an easy cleaning and maintenance.”


Cummins to target Europe rental market with launch of new gensets

Tue, 01/22/2013 - 17:36 -- Ruth Williams

Cummins is targeting the European rental market with the launch of four generator sets in the 150 to 300 kVA range.


According to International Rental News, the rental-specific sets, which have been created by a new Cummins design team led by former A-Plant power rentals director Richard Mellard, are sized at 150, 200, 250 and 300 kVA, with the smaller two using Cummins QSB7 engine and the two larger models equipped with the QSL9 power unit

The sets will be made available in markets including Europe, the Middle East, Asia Pacific and Australia. The reports said Cummins would further expand their rental range, with launches of sub-150 kVA units by the end of 2013 or the start of 2014, and larger units following in 2014/15.

The gensets come equipped with Cummins’ PowerCommand controllers, although Cummins plans to offer third-party controllers for rental companies who want commonality across their fleets. The 150 kVA unit can be used in temperatures up to 500C without any derating and the 200/250/300 sets up to 400C with no derating.
