ADR spend to climb to $185.5m by 2023

ADR spend to climb to $185.5m by 2023

Worldwide spending on automated demand response systems will grow from $13m in 2014 to $185.5m by 2023, according to market analysis.


In a new report, Navigant Research forecasts increased automated demand response (ADR) system adoption in world regions where new market sectors such as ancillary services – for example, reserve and regulation – are opening up to demand response.  The report points to the changing resource mix in electric grids around the world – specifically the growing adoption of intermittent renewable energy sources requiring backup power – as creating increased potential for demand response to play a pivotal role.


However, barriers to ADR adoption also exist, including users’ continuing desire for control, security issues, production concerns in the case of industrial facilities and comfort concerns for commercial buildings or households.


The report also points out that, depending on the level of existing energy management systems in a facility, costs for ADR could be relatively small and involve little to no hardware installation, or they could require extensive control installations and lots of integration with existing systems, so a cost/benefit analysis is required.


Almost all current ADR activity is centred in the US, but this leadership position will erode over the next 10 years according to Navigant. Asia Pacific is predicted to overtake North America in ADR capacity and spending after 2020, while Europe’s growth will be slower than Asia Pacific’s but faster than North America’s, the report said.


“Demand response is a growing part of the resource base that electric system operators use to maintain grid reliability, and automated DR greatly extends the reach and capability of the technology,” said Brett Feldman, senior research analyst with Navigant Research. “Much of the basic technology for ADR exists today, and to a large extent, ADR adoption will depend more on market forces than on technical advances.”

GE gensets to float in Brazil

GE’s Distributed Power business is to supply 85 MW of on-site power for floating oil and gas production in Brazil.


Four LM2500+G4 aeroderivative gas turbine generators will be shipped to Tokyo-headquartered general contractor Modec, which specialises in the engineering, procurement, construction and installation of floating production systems.


The generators will be installed on Modec’s floating oil and gas production, storage and offloading (FPSO) vessel the Cidade de Caraguatatuba, which will operate in 2240 metres of water in the pre-salt fields off Brazil’s coast.


The generators are planned to power the vessel’s production processes, water reinjection, gas compression and process heating. Non-commercial grade ‘field gas’, produced on-site, will fuel the units, reducing greenhouse gas emissions, according to GE.  


Shipment of the units is planned for late 2014 and installation for 2015, with commercial operation to commence in 2016 or 2017, GE said.


The agreement represents the two companies’ latest vessel set order, following previous orders for projects in Brazil and Africa. In June 2013 GE announced it would supply an earlier group of four LM2500+G4 aeroderivative units for an FPSO platform in Brazil's pre-salt field.


"This latest order for our aeroderivative gas turbines reaffirms GE's leadership in supporting the diverse on-site power needs of Brazil's offshore industrial sector as it develops the country's energy resources," said Lorraine Bolsinger, president and CEO of GE’s Distributed Power business.


 

Aggreko backs up Turkish bridge project

Aggreko backs up Turkish bridge project

Aggreko has won a contract to provide backup power for the construction of the world’s fourth longest suspension bridge in Izmit, Turkey.


The bridge, 50 km southeast of Istanbul, is to be the centrepiece of a new, state-of-the-art highway system linking Izmit and Istanbul.


Under the terms of the contract, Japanese construction company IHI Holding, the project’s leader, is to receive 8.6 MW to ensure that critical safety systems and processes remain operational in the event of any disruption in local grid power. Meanwhile, Turkish engineering and construction firm Sezai Türkeş Feyzi Akkaya (STFA), which is building earthquake-resistant pylons for the project, is to receive 2 MW.


As the bridge is located in an earthquake-prone region, STFA said its pylons will be built into earthquake-resistant concrete foundations that will sit on a layer of gravel on the seabed. Aggreko’s power will run the pumps and other dredging activities involved with fixing the pylons in place at depths of up to 40 metres below sea level. Aggreko said its equipment will be mounted on tugboats for transport to the site.   


“Aggreko is well-known for their high quality service and reliable generators. We were delighted they could provide us with a complete solution and offer the flexibility to rapidly increase our power supply as and when needed. The equipment is fuel-efficient and Aggreko’s customer service is top-notch,” said Umit Kaymaz, deputy manager of administration at IHI Infrastructure Systems.


“STFA has a long history of working with Aggreko. We are satisfied with their speed of delivery and strong business ethics. The time frames of this project were critical as the caissons needed to be submerged as per the schedule without any delays, be they due to unexpected causes or equipment failures,” said Bahadir Imirzaloglu, STFA’s project manager.  

Powering the data centre of the future

Powering the data centre of the future

Industry professionals believe the data centre of the future will be powered by on-site generation and will use high-efficiency AC UPS systems for backup power, according to a new survey.


Emerson Network Power’s report, The Data Center 2025: Exploring the Possibilities, surveyed 800 data centre professionals around the world.


A majority of survey respondents (65%) said they believe the future’s ‘hyperscale’ data centres will run on on-site power by 2025. Respondents in the Asia Pacific region overwhelmingly predicted a move to on-site power, with 33% saying it will definitely happen and an additional 44% considering it likely.


Solar power was in the lead for respondents’ future power source of choice. Asia Pacific and Latin America were optimistic about solar’s potential, with each region predicting that 25% of future data centres’ power will come from solar, while Western Europe (18%) and the US (15%) projected lower levels of solar use.


For backup power, 30% of participants expect high-efficiency AC UPS systems to be the primary source in 2025. According to the respondents, these UPS systems are less likely than other technologies to be displaced by competitors due to efficiency advancements in recent years.


But some said hardware approaches could challenge the AC UPS, including a momentary duty inverter that provides just enough ride-through power to switch to an alternate source (27%) and DC UPS (13%). And about one in four participants said software failover could become the new backup paradigm, displacing today’s UPS/generator combination.

$6.75m for UK energy storage research project

The UK’s Engineering and Physical Sciences Research Council (EPSRC) has given £4m ($6.75m) for a research project that aims to set the nation’s energy storage course.


The Supergen Energy Storage Hub will draw together experts from seven universities and 14 industrial and governmental partners to address the technical and scientific challenges facing energy storage technologies and develop an energy storage roadmap for the UK.  The project also aims to accelerate the process of scaleup, prototyping and commercialisation.


Professor Peter Bruce of Oxford University, the project’s leader, said, “Energy storage is more important today than at any time in human history. It has a vital role to play in storing electricity from renewable sources and is key to the electrification of transport. The Supergen Hub will be working with industry, government and the education system to improve the performance of electrochemical, mechanical and thermal devices, develop and tested new materials and optimize thermodynamic processes, all against a background of robust integrated systems.”


Philip Nelson, EPSRC’s CEO, said, “Developing efficient energy storage technologies and infrastructure is crucial to decarbonizing and strengthening our energy system and security. Working with industry, this new Supergen Hub will move the UK closer to where it needs to be for a safer, more sustainable future.”

Texas lead-acid storage project a boost for batteries

A successful lead-acid battery energy storage project in the US state of Texas could lead to more batteries on the state's grid.  


Duke Energy’s pilot Notrees Wind and Battery Storage project was built near the town of Notrees with help from a $22m grant from the US Department of Energy and batteries from Xtreme Power.


The project is the US’s largest battery storage installation at a wind farm.


Between January 2013 and February 2014 the 36MW batteries, storing energy from the nearby 153MW wind farm, exported 10,000MWh to the state grid, which is run by the Electric Reliability Council of Texas (ERCOT).


“The speed and accuracy of the system’s response during the pilot confirmed the benefits of the Notrees Battery Storage Project and ERCOT has made it a permanent market service,” said Tammie McGee, communications manager at Duke Energy.


The project’s success could also lead to more Texas battery storage in future, said Suzi McClellan, state affairs director at market consultancy Good Company Associates.


“There’s definitely a future there,” McClellan said. “The batteries stabilise the voltage, provide power when the wind stops blowing or charge up when the wind power isn’t needed.”


Analysts say battery energy storage could become a larger part of Texas’ electricity infrastructure, especially since the national Energy Storage Association has begun work with ERCOT on a market redesign.

Bredenoord expands mobile hybrid generator production

Bredenoord expands mobile hybrid generator production

Netherlands-based rental power firm Bredenoord says it will produce an extra 30 of its ESaver mobile hybrid generator systems and put them on the market through its rental programme.


The move comes after a successful test run of the systems in partnership with contractor Dura Vermeer, which piloted 10 of the ESavers.


The 15kVA, 3ph, 400V Esaver system comprises a battery pack that recharges via solar cells, in conjunction with a diesel generator. At peak power demand times or when the battery charge is low, the generator engine switches to full capacity. The system can be combined with power generators with varying capacities, Bredenoord said.


In late 2013 Bredenoord and Dura Vermeer completed a pilot project that used 10 400V ESaver systems in combination with a 15kVA generator for construction and infrastructure projects. The companies reported that initial estimates of 40% fuel savings had been exceeded and that 70% savings are possible under certain conditions.


"The online ESaverclient portal provides clients with continuous site monitoring of their fuel savings and emission reductions”, said Margien Storm van Leeuwen, new business and marketing manager at Bredenoord. “We analyse this data and thus, together with the client, we can ensure the best possible use in each specific situation. [This] results in considerable savings, and has been an important motivation in further expanding production”.


Bredenoord general manager Jaap Fluit said, “We are heading for a society in which we will be more careful in our use of natural resource and emission. In practice the ESaver proves perfectly well that trustworthiness, certainty and sustainability can be combined with optimal cost-effectiveness. In particular by making existing technologies more sustainable we create a win-win situation. Fuel-savings by means of using our current machinery."


 


 

Tackling rogue traders with engineer certification

Tackling rogue traders with engineer certification

To combat a growing number of ‘rogue traders’ providing unauthorised maintenance services to its customers, UPS and standby power systems manufacturer Riello has launched an engineer certification programme.


The Riello Certified Engineer programme aims to protect customers who require third party UPS servicing and approved spares by allowing them to check their chosen engineers' training status.


To achieve Riello Certified Engineer status, engineers from Riello resellers must successfully complete comprehensive training on the commissioning, maintenance and servicing of the firm's UPS products. On completion of the training, engineers are given an ID card with a unique identification number which customers can use to search a dedicated website to verify their certification status.


Leo Craig, Riello general manager, said, “Several other UPS manufacturers have chosen to tackle the problem of unauthorised maintenance by instigating ‘closed protocol’ systems.” In such a system, a service engineer needs licensed access to the software that communicates with the UPS, while in an ‘open protocol’ system third-party service companies can install and maintain the system.


“We chose not to take this approach because we felt that it would stifle competition in the market,” Craig continued. “Instead, we’ve created a comprehensive network of qualified service partners ... which we hope will offer our customers the reassurance they need.”


 

New York’s petrol stations to add backup power

New York’s petrol stations to add backup power

Around 250 petrol stations in upstate New York, US are to receive federal funding to purchase emergency backup power capacity.


The funding was approved as part of the state budget.


Grants from NYSERDA, the state’s energy and development authority, will give participating petrol stations either $10,000 to offset the cost of a transfer switch to connect portable generators in times of need, or $13,000 toward the cost of both a transfer switch and permanent generator.


An additional $3.1m will be made available through federal funding related to Superstorm Sandy.


According to the state a list of petrol stations eligible for the scheme is still in the works, but it will likely include about 250 stations.


In 2013 New York passed the Fuel NY initiative, which required most petrol stations in the heavily populated downstate areas of New York City, Long Island, and Westchester and Rockland counties to install backup power systems by 1 April, 2014 and to deploy and install a generator within 24 hours of losing power during a fuel supply or energy emergency. The move came after 2012’s Hurricane Sandy caused significant fuel shortages in the NYC area.


This year’s state budget creates an additional voluntary backup power scheme for petrol stations in the more rural upstate region if they are within one half-mile of a highway exit or a hurricane evacuation route. Petrol stations can opt into the scheme until October 2015.  


James Calvin, president of the New York Association of Convenience Stores, said, “This plan will provide incentives to gas stations on or within a half mile of exits of interstate highways to voluntarily equip their facilities to remain capable of pumping fuel in the event of a prolonged power outage.”


New York is the first US state to make such a strategy into law.
