ABB, the Switzerland-headquartered power electronics specialist, has this week secure a couple of big project supply deals in the wind and solar energy sectors.
In the U.K., ABB will supply a 2 MW battery energy storage system to support the integration and transmission of electricity generated by the 90 MW Burbo Bank offshore wind farm that sits off the coast near Liverpool.
The storage device will help to stabilize the frequency of the U.K. grid at 50 Hertz (Hz), which is the level operated by the National Grid. Storage solutions are increasingly being adopted in the U.K. now that solar and wind energy supplies a sizeable percentage of power to the grid.
The intermittent nature of wind power in particular can cause stresses to grids, and the hope is that this battery will help to flatten out the peaks. “Energy storage is playing a key role in the evolution of the power network and is a strategic focus area to reinforce our position as a partner of choice for a stronger, smarter and greener grid,” said ABB’s GIandomenico Rivetti, who is MD of the high voltage products business unit in the company’s power grids division.
Having this week reached the milestone of 5 GW of inverters installed in India, ABB has also announced that it has secured a contract to supply solar inverters to 750 railway stations in northern India – one of the busiest railway networks in the world.
“Solar inverters for this project vary between 5 kW to 50 kW in performance depending on the size of the station,” said an ABB statement. “They will be part of the solar installations being set up by Azure Power.”
Indian solar power developer Azure Power is installing solar arrays at a number railways in India. Indian Railways has targeted an installation goal of 1 GW of solar power at its stations across the country. Currently, there is 36 MW of solar capacity installed at India’s railway stations.
