US demand response provider EnerNOC has expanded its presence in Southern California through a new contract with Southern California Edison.

Under the terms of the new contract, EnerNOC will increase its number of megawatts in SCE's service territory by approximately 15% through December 31, 2014, consistent with the term of EnerNOC's expanded contract with PG&E announced in a press release dated February 5, 2013.

EnerNOC won the additional megawatts through a competitive bidding process in which EnerNOC was awarded more than twice as many megawatts as any other third-party provider, and more than 40% of all megawatts awarded to the six successful bidders.

This contract covers a utility service territory where EnerNOC also has contracts to deliver commercial and industrial energy efficiency services, allowing customers in the region to benefit from an integrated energy management portfolio comprised of both demand response and energy efficiency solutions.

Manufacturer of industrial floor cleaning equipment, Nilfisk-Advance Group, has introduced an industrial combination floor sweeper-scrubber powered by a hydrogen fuel cell.

The Advance CS7000 operates solely on hydrogen for emission free operation in response to demands for alterative fuel options for industrial equipment.

The machine has a Plug Power fuel cell that will run for an operator’s full shift between refuelling and allows for 24/7 operation because of rapid refuel capabilities.

“This first-of-its-kind fuel cell-powered unit provides a sweeper-scrubber solution for customers who have already invested in fuel cell technology, allowing them to further leverage their fuel cell investment and infrastructure,” said Jeff Barna, President and General Manager of Nilfisk-Advance.

Spanish genset OEM Himoinsa has unveiled the HVW480, a genset specially designed for integration into mobile cranes.

Last June, Himoinsa reached an agreement with Paceco Espana, a company that designs and manufactures cranes and container shipment & handling systems, to supply power to five RTT Transtainer cranes in the Port of Tenerife.

After several months of work, the Power Solution engineering team of Himoinsa designed the HVW480 generating set. Features of the EU stage IIIA-compliant HVW480 genset include: a fastening system to prevent detachment caused by crane movement; correctly dimensioned for loads with high harmonic distortion and load variations during aggressive work cycles; and paint and hardware treatment, suitable for working in saline environments at seaports.

The crane incorporates a fuel-saving system, so that during waiting time until vehicles arrive to load or unload goods, the system automatically reduces the revolutions of the diesel group to minimum tick over speed, resulting in fuel saving. 

Aggreko provided 13MWs of power to the 2013 Super Bowl at the New Orleans Mercedes-Benz Superdome. There is a lesson to be learned about the importance of backup provisions following the much talked about low-light of this year’s American football clash - the power cut in the second half.

Aggreko provided back up power for the halftime show and to the designated press areas for national and international broadcasters aas well as to VIP sections – resulting in no disruption in these areas.

The problem was with the stadium power, provided Entergy, which had no back up power supply. In a statement Entergy said the problem related to a piece of equipment monitoring the electrical load detected a system abnormality and caused the power to be cut off.

This high profile power outage lasted 35 minutes, and halted the game until the problem was fixed.

SPP Pumps has selected Finning to supply two custom Cat 3512C HD engines to drive firewater pumps for the UK North Sea’s ATP Cheviot oil and gas production platform – a semi-submersible drilling, production and storage facility due for completion in 2013.

The Cat marine engines, rated at 1678 kW at 1800 rpm, are packaged with accessories by Finning to meet both the client’s specification and the stringent requirements of NFPA 20, the National Fire Protection Association standard.  This is to ensure the engines will deliver reliable power in the event of a fire emergency.

These refinements required a number of modifications to the engine controls to meet NFPA 20. The engine rating is approved by the American Bureau of Shipping (ABS) as required for the floating platform.  This, in particular, meant that Finning had to design the engine package to maintain operation at a constant 22.5-degree tilt in the event of an emergency, such as the platform losing buoyancy.

Each firewater pump engine is certified to EPA marine tier two classification and meets the E3 emissions’ test cycle for marine applications.  NFPA requirements also specified the addition of a dual engine control module (ECM) so that, in the unlikely event of failure of the main ECM, the second module will maintain the engine systems and performance will be unaffected.
