Mission Statement"A forward thinking dynamic Company driven

by the needs and expectations of itscustomers, focused on delivering individualand tailor made utility infrastructure

solutions with uncompromising dedication."

About UsProviding utility infrastructure and connections has evolved significantly over the past five years.However, whilst the end product has not changed much, service, delivery and overall customer care isperceived to be getting worse.

Matrix Networks Renewables was conceived to enable developers to access a company that actuallycares and is passionate about delivering utility networks. A company that is really interested in its clients andaims to remove the frustration commonly associated with dealing with large, unwieldy utility providers.

Our clients concentrate on developing sites; Matrix Networks Renewables concentrates on thedelivery of utility infrastructure to those sites.

Our people have many years’ experience in managing Electrical connections both as a DistributionNetwork Operator and that of an Independent Connection Provider.

Matrix are fully Lloyds accredited for Design and Installation up to and including 132kv(please see case histories for more details).

Matrix Networks Renewables are part of the Dunamis Group.

EcotricityGalsworthy Wind Farm, Devon

Matrix Networks Renewables undertook, the design andconstruction of the 132/33kV substation connection into the local132kV Over Head line network. Supplying 9.5MVA from the nearbyGalsworthy Wind Farm.

The open terminal compound with aluminium tubular busbars, is designed tothe DNO (Western Power Distribution) requirements, which includes all Steelstructures for equipment, structure footing, system earthing, Transformer bund,Control/33kV building and the construction of the High security palisade fence.The design also of the HV protection network, SCADA system andcommissioning there of.

Due to the inclination of the land on which the site is placed remedial groundworks known as “Cut and Fill” on two levels were undertaken, with a Gabion

wall built between the DNO and Customer compounds, which became an idealline of ownership demarcation. A non-environmentally sensitive stream had tobe diverted to avoid the customer 132/33kV transformer compound.

The building design is standard layout but due to the levels across theownership boundary the building in turn has two distinct floor levels. Thebuilding is finished in Natural Cut & Tumbled stone with a slate roof in keepingwith local building requirements.

Area lighting of the compounds and security CCTV is achieved by columnmounted luminaires and cameras strategically placed through the compounds.

Lightsource Renewable Energy LtdMuncey & Black Peak PV Farms, Melbourn, South Cambridgeshire

Matrix Networks Renewables undertook the design and construction of the 132kV connection into theMelbourn Grid, supplying 2 number 20MW PV farms.

The open bar compound with aluminium tubular busbars was designed to the DNO (UK Power Networks)standards, which included installation of UKPN adopted 132kV passmo circuit breaker, customer privatenetwork 132kV/33kV transformer, 33kV switch boards, all steel structures for equipment, structure footingsand earthing systems, transformer bund, control 33kV building and the construction of the high securitypallisade fence. The design included the HV protection network, scada system, and commissioning there of.

Excavation, reinstatement and installation of approximately 4.5km of dual circuit 33kV cabling to connect totwo number 20MW PV farms.

AGR Group LtdFenland and Green End PV Farms, Chittering, Cambridgeshire

Matrix Networks Renewables undertook the design and construction of a special double brick built substationto enable 2no. 20MW PV farms to be connected into Landbeach Primary substation via independent fibreprotected ringed feeder circuits.

Excavation, reinstatement and installation of approximately 7km of dual circuit 33kV cabling and fibre networkto connect each 20MW PV farms was carried out. At each site a double GRP switch house was establishedcontaining DNO 33kV switch gear and protection equipment and customer’s 33kV switch gear and protectionequipment.

A local 11kV pad mount transformer was provided for auxilary LV supplies.

Push Build LtdChurch Farm PV Farm, Croydon, CambridgeshireMatrix Networks Renewables undertook the design and construction of the Constable network to connect the17MW PV farm at Croydon onto the DNO network. The project consisted of ‘ringing in’ the new substation to thenetwork via a fibre protected feeder circuit, and modifications to UKPN’s network.Excavation, reinstatement, and installation of approximately 2 km of 33kV cabling and fibre network to connectthe PV farm was undertaken.On site a brick built substation was constructed containing a 3 panel 33kV switch board, ancillary and protectionequipment.A local 11kV padmont transformer was also provided for auxiliary LV supplies.NOTE: Part of the agreed connection offer from UKPN was a conditional requirement for them to efficiently ‘turndown’ the generation export to an agreed level at times of abnormal demands on their network. A sophisticated protection scheme was designed, approved, and installed to curtail the export as and when needed.

Vine Solar132/33 kV 39 MVA Point of Connection (POC) substation(Wendy – Cambridgeshire)

The open compound 132/33 kV substation with tubular busbars, designed and constructed to the local DNO(UK Power Networks) standards, is located within a 41m x 21m x 5m high screen enclosure, which was aprerequisite for planning approval by the local planning authority.

Planning requirements stipulated that no equipment would be any higher than 5.4 m and not be visible toneighbouring properties. The transformer alone is 6.95 m high and is situated within a deep bund.

The DNO 132 kV switchgear is contained within an ABB “PASS-MO” unit which fits well into the very limitedspace available.

The design included all plant structures, footings, HV protection, SCADA systems and the completecommissioning of the scheme.

The 132 kV connection to the DNO grid, is back along an underground cable route of 7 km, crossing theA1198, numerous secondary roads, farm tracks, ditches, arable farm lands of many owners and a rail crossing.

The solar farm connection consists of three individual strings, feeding into the transformer by way of a fourpanel 33 kV switchboard with associated control equipment and housed within a GRP enclosure.

South Creake 132/33 kV 23 MVA Point of Connection (POC) substation(Hempton near Fakenham Norfolk)

The open compound 132/33 kV substation with tubular busbars, designed and constructed to the local DNO(UK Power Networks) standards, is located 200 m from the local grid substation.

The DNO 132 kV switchgear is contained within an ABB “PASS-MO” compound, with GRP control room andfibre optic communication between the sites.

The design included transformer bund, switch/control rooms, all plant structures, footings, HV protection,SCADA systems and the complete commissioning of the scheme.

The solar farm connection consists of an individual 33 kV circuit approximately 7 km North West of the site,which included a 485 m directional drill beneath an SSI and river.

As a final stage of the project an extensive horticultural screen of local flora was designed and implemented tofulfil local authorities planning requirements.
