Solidus Power (formerly Arhan Power Pvt. Ltd.) delivers specialist EPC power infrastructure services across Transmission & Distribution, Gas Insulated Switchgear, Substation Automation, and Grid Connectivity for large-scale solar, with the technical depth of a multinational and the accountability of a team that still picks up your call.
Managing a Transmission & Distribution project means coordinating engineering, procurement, installation, testing, and commissioning, across multiple vendors, timelines, and technical dependencies. One gap in scope means delays, cost overruns, and a project that doesn't perform as designed.
Solidus Power takes complete ownership of your T&D turnkey project from first design to final commissioning. We identify what the scope is missing before it becomes a problem on site. We source high-quality equipment from reputed manufacturers. We install, test, and hand over with documentation that holds up to ISO audit.
Substation design, single-line diagrams, load flow analysis, built for your specific site and load requirement.
Transformers, switchgear, circuit breakers, protection relays, sourced from reputed manufacturers with full traceability.
Site-experienced teams with ISO-compliant processes. Siemens-standard site setup from day one.
Rigorous pre-commissioning checks, relay coordination, and final commissioning, no shortcuts.
Substation SCADA integration for real-time monitoring, control, and remote visibility of your entire network.
Full cost transparency, material costs, project management charges, and margin visible to the client.
Gas Insulated Switchgear is precision advanced technology. It reduces a conventional substation's footprint by up to 10 times, making it the critical solution for space-constrained urban sites, data centre substations, metro infrastructure, and industrial campuses where land is at a premium.
Most EPC contractors in India take GIS orders and then rely entirely on OEM supervisors to execute. Solidus Power is different. Our team has independently delivered GIS substation installation at 220kV, understanding every sequence, every handling requirement, every pre-commissioning check, with OEM partners confirming our execution capability. We pre-empt site requirements before OEM supervisors arrive, not after.
Independent installation and commissioning at EHV level, without full OEM dependency on site.
Space-optimised substation solutions for data centre power infrastructure, critical where footprint and uptime are non-negotiable.
Proven delivery on metro rail and high-density urban infrastructure projects where conventional substations are not viable.
High-precision switchgear installations for manufacturing, processing, and industrial campus power networks.
We show clients the full total cost of ownership, not just capital cost, so the GIS investment decision is grounded in real numbers.
Deep relationships with Siemens, GE, and Hitachi, we speak their language and pre-empt site requirements before they arrive.
WORK PROCESS
Your work maybe small compared to the big giants, but you are at the top of the list for commitment, workmanship, and site setup.
A substation is only as reliable as its ability to be monitored, protected, and controlled in real time. For data centre power infrastructure, industrial campuses, and utility networks where any outage translates directly into revenue loss, substation automation is not optional, it is the difference between a functioning asset and a liability.
Solidus Power designs and delivers complete substation automation systems, from protection relay coordination and bay controllers to full SCADA integration, with the engineering rigour of a team that understands both the electrical and the operational consequences of getting it wrong.
Relay coordination, differential protection, busbar protection, designed for your specific fault scenario and load profile.
Full supervisory control and data acquisition, remote visibility, alarm management, and control from a central point.
Intelligent electronic device integration for accurate data acquisition and bay-level automation.
Power quality monitoring, demand management, and energy analytics, built into the automation layer.
IEC 61850 and legacy protocol integration, fibre, ethernet, and serial communication architecture built for reliability.
Full factory acceptance testing and site acceptance testing before go-live, no shortcuts on commissioning.
India's renewable energy buildout is accelerating, and the gap between solar generation capacity and reliable grid connectivity is one of the most critical infrastructure challenges in the sector. A poorly engineered solar power plant substation or grid interconnection creates instability, regulatory risk, and revenue loss from curtailment and outages.
Solidus Power brings its full EPC substation capability to large-scale solar projects, designing and delivering the HV/EHV substation, grid interconnection, protection systems, and SCADA that ensure your generation asset performs at its designed capacity, reliably, and in full compliance with CERC and SERC requirements.
Engineering and execution of grid-connected substations for utility-scale solar including GIS where site constraints apply.
Transmission line interconnection design, protection coordination, and synchronisation with the state grid.
Complete power evacuation infrastructure from the inverter output to the grid injection point, designed for minimum losses.
Generation monitoring, grid compliance logging, fault detection, and remote plant visibility through integrated SCADA.
CERC, SERC, and SLDC compliance built into design and commissioning, avoiding costly post-commissioning rework.
Substation and automation design for floating solar, hydro, and hybrid renewable energy configurations.
