equipment. Te new circuit breakers provide greater operational flexibility and resilience for the local and regional transmission network. “Te work we have done to enhance our infrastructure is expected to benefit more than 19,000 customers in Burlington County,” said Anthony Hurley, JCP&L vice president of operations. “By upgrading the substation in Wrightstown our system should be more resilient and provide us with more options to help shorten the duration of power outages, if they occur,” he added. Te project is part of JCP&L’s
previously announced plans to invest US$251 million (£156 million) in 2014 on service reliability enhancements and other work, including its ‘Energising the Future’ transmission projects. Also in the USA, construction
is underway on a new FirstEnergy transmission substation in Doddridge County, West Virginia, to support the electric demands of the area’s rapidly expanding Marcellus Shale gas industry and help enhance service reliability for Mon Power’s customers in Doddridge and neighbouring counties. As part of the construction process,
crews recently completed the foundation work and erected steel structures at the new 11 acre substation site near Sherwood, West Virginia. Te US$36 million (£22 million) project also includes a short transmission line to connect the new substation with an existing 138kV line located nearby.
Te new substation will be connected to MarkWest’s Sherwood processing facility via two, four-mile transmission lines. Te plant is a midstream processing facility that separates natural gas into dry and liquid components. Te refinement and separation processes typically use large amounts of electricity. Te new substation has been designed so that it can be expanded in the future to accommodate additional load growth at the MarkWest facility.
Opening Soon Te new substation is expected to be completed and operational in December 2014. Trans-Allegheny Interstate Line, a FirstEnergy transmission affiliate, will build and own the substation. Mon Power will own the short transmission line connecting to the existing 138kV line, as well as some metering equipment inside the substation. Finally, officials of the Tamil Nadu
Generation and Distribution Corporation (Tangedco) in India have told Te Hindu newspaper that administrative sanction has been given for constructing a new 110/33/11kV substation inside Phoenix Market City mall, at a cost of Rs 74 crore (£7.4 million). It has also been proposed to install an additional transformer of 16MVA capacity in the existing substation, where three 16 MVA transformers are currently available, and a total of 50 transformers across Velachery, to prevent the low voltage fluctuations experienced in various parts of the city and region. l

£14m investment to boost Birmingham power network “It ensures that we can provide a high level of
ore than £14million is being spent on a major initiative to boost power supplies in Birmingham, UK. Western Power Distribution (WPD), the
electricity distributor for the region, is committed to investing in its network to further improve supply reliability and customer service levels. This new initiative involves the construction of a new
substation in Hockley and the laying of around 8km of new 132,000 volt cable to connect the new substation to three existing substations at Nechells, Summer Lane and Winson Green. This will help to further safeguard supply reliability to around 41,000 customers in the city centre. WPD’s investment is also designed to better
accommodate any increased demands placed on the power network in the future for additional developments.

service to these areas in the long term by improving the infrastructure and security of our electricity network,” said Mick Dunne, WPD’s projects manager for the area. The project, which has recently started, is expected to
be complete in late 2015. Cable laying work is expected to be completed by April 2015. During this period, traffic management will be in place in Birmingham in order to enable WPD’s contractors Prysmian and Durkin and Sons to lay the new cables near the city centre. “While this work is being undertaken, our aim is to keep
any disruption to an absolute minimum. We have been liaising with Birmingham City Council to agree on a cable route which creates the least disruption for traffic flow in the area,” added Dunne. l
Synchronous condenser technology generates adjustable reactive power to ensure the grid stability.
Austrian Power Grid has awarded Pöyry with a project for the construction of new 380/110/30kV switchgears at Kaprun substation, Austria.
“With the increase in renewable energies we are seeing for example in Europe and the USA, we expect demand for adjustable reactive power generation to increase in the years to come.” – Axel Kossmann, Alstom Grid.
