In February 2013, the capacitor plant in Brazil supplied two three-phase, single tunned filter capacitor banks, two three-phase, thyristor-switched capacitor banks and surge ca pacitors. These capacitor banks were designed to support a high seismic requirement (0.45 g) and a very low temperature (40 C).
STF and TSC capacitors units were designed with internally fused technology and surge capacitors with unfused tech-nology. Type and special tests were performed according to CAN/CSA 60871:03 to assure design is able to with-stand environmental and electrical requirements.

The HVDC system operated by Adani Power Ltd. has a transmission capacity of 2,500 MW and provides low-loss energy transmission over a distance of approximately 960 km, from the port of Mundra located on the west coast to the industrial regions in the Haryana state.
The AC filters for this HVDC system represent the first large order for the capacitor factory in Jundia, which delivered the first units to India only six months after the official inauguration in December 2009. The total installed output of the 54 single-phase, high-voltage AC filters was close to 4,000 Mvar and the total number of units supplied was 4,840 (including spare parts).

Siemens was awarded the FACTS systems for the 1,800 km (> 1,000 miles) long 500 kV high-voltage transmission line connecting the Tucuru Hydro Power Plant with the city of Manaus in 2010. The scope of the project included a total of 18 fixed series capacitors located at five different substations in the Amazon forest.
The capacitor factory in Jundia was responsible for the supply of all the capacitors for this project, which, at the time, was considered to be the largest FACTS project ever executed worldwide.

The Lincs project, owned by Lincs Wind Farm Ltd. is located in the Greater Wash Wind Farm Park, England and gener-ates a capacity of 270 MW. The energy generated offshore is transferred to the grid via the Walpole Onshore Sub-station located in Norfolk Country. Siemens was awarded the contract for the construction of the onshore substation in 2010. The Siemens high-voltage capacitor plant provided a total of six single-phase capacitor banks for the 132 kV-MSCDN, comprised of fuseless C1 and C2 banks, with a total installed rating of 246.3 Mvar, as well as six single-phase banks with internally fused capacitors for the 13.9 kV MSC, with a total output of 145.7 Mvar.

The Dudgeon Offshore Wind Farm Project is located in the North Sea, approximately 32 km off the UK coast at Cromer, Norfolk. The wind farm generates a total capacity of 402 MW. This power is collected at 33 kV by an AC off-shore substation platform, before being exported to shore at 132 kV. In 2015, Siemens was awarded the contract to supply capacitor banks for two 132 kV MSCDNs located in the Necton Onshore Substation. In total, there are six single-phase capacitor banks, comprised of internally fused C1 capacitors and unfused C2 capacitors. Due to extremely low sound pressure requirements, the capacitor units were specially designed and the banks were supplied with sound damping hoods.
