The plant has a distinctive 131 meter extrusion tower, built to allow the insulation material to cool symmetrically around the metal cable conductor. It is ABB’s first high-voltage cable plant outside Europe, and will manufacture high-voltage transmission cables for both AC and DC applications.The cables produced at the new facility are also well suited to bringing power from remote wind and solar installations to the grid. More than 130 people will work at the $90 million facility built by ABB.

The need to replace old, fragile transmission and distribution (T&D) power infrastructure and inject more power into the grid is pushing electricity utilities across Southeast Asia to strengthen and expand the T&D power infrastructure. Poor grid connectivity to remote villages too is compelling electricity utilities to lay out comprehensive plans to extend electricity to new regions. As a result, the T&D substation market in the region is expected to see sustained growth.

This article, the first in a three-part series, focuses on the need for a new class of distribution grid infrastructure, one that enables distribution utilities to dynamically manage power flow from sub-station to load, ensures end-to-end power quality and reliability in the face of increasingly dynamic grid conditions, and drives greater systemic efficiencies, all based on a business case that stands alone without reliance on subsidy.

One part power electronics and one part networking and communications technology, microinverters and DC optimizers (commonly referred to as module-level power electronics, or MLPEs) are playing an increasingly significant role in large-scale and distributed renewable electricity generation.

But the LEDs are far from the full story. As long as cities are sending a truck out anyway, they are also installing other gadgets to take advantage of the fact that street lights a) already have power, b) are pervasive throughout the city and c) are perched on a high vantage. They are installing such things as: Communications modules to create a canopy network throughout the city Security cameras Proximetry sensors that dim the lights when there's no one around Software to strobe the lights to lead police and fire to the site of an emergency

Transmission development has not kept pace with electricity generation in the 10th and 11th plan, resulting in the lack of sufficient transmission capacity. India has installed capacity of 225 GW, yet we are able to meet peak demand of only 123 GW - one of the key reasons being lack of sufficient transmission lines.

E.ON Netz is using an aluminium underground cable from Nexans in the expansion of its grid infrastructure for wind energy. In the administrative district of Dithmarschen, Nexans has installed a double circuit 110-kV underground cable system for E.ON – the first of its kind for a German customer – with a total length of around 5.5 km and an order volume of € 4 million. The section that has now been connected up is part of the concept of the federal state government of Schleswig-Holstein to transport wind power electricity inland along the coast in a 20-km wide corridor via underground cables. As part of the energy turnaround, E.ON Netz has embarked upon an infrastructure project that will enable a future feed-in of 9000 MW of electricity from offshore wind farms into the 380-kV transmission grid along the west coast of Schleswig-Holstein.

By next March, utilities must submit applications to buy storage to supply 1% of projected peak demand for 2020. Pumped hydro is not eligible.

Promoted by key projects including large-scale long-distance power transmission, ultra-high voltage grid construction, power grid construction in new rural areas and railway electrification reconstruction, the power transmission and distribution and control equipment industry of China achieved rapid development in 2009, with the annual sales revenue and total profit of RMB 656.19 billion and RMB 49.13 billion, a YoY rise of 15.7% and 19.5% respectively. Boosted by the fast growth of power transmission & distribution and control equipment industry, five sub-sectors mounted up vigorously in 2009. In particular, capacitor and corollary equipment sub-sectors showed the most rapid growth, with the prime operating revenue and total profit increasing by 28.3% and 63.3% respectively from a year earlier. This can be ascribed to the following three factors: firstly, China has made much progress in the development of ultra-high voltage and extra-high voltage technologies; secondly, it is the period from 2009 to 2010 that the ultra-high voltage demonstration projects in China have been constructed in succession, characterizing huge investment; thirdly, China has actively promoted the concept of energy conservation and emission reduction and paid increasing attention to voltage quality, safety and electricity saving, etc.

It is now well established that ultra-high voltage (>10kV) Silicon Carbide (SiC) device technology will play a revolutionary role in the next-generation utility grid.
