What Electric Power Group does

Electric Power Group (EPG), a privately held California LLC founded in 2000 by Vikram Budhraja and headquartered in Pasadena, develops and commercializes synchrophasor (PMU-based) software for wide-area real-time monitoring, situational awareness, and analytics of electric power grids. The platform processes high-resolution, time-synchronized phasor data through an end-to-end stack of more than 15 production applications spanning data concentration (ePDC), state estimation (eLSE), real-time dynamics monitoring (RTDMS), offline analytics (PGDA), data quality (DataNXT), visualization (PhasorNXT, PhasorSmart), generator model validation (GMV), automated event mining (AEM), operator training (PSOT), data extraction (ePDE), and asset/event notification (iTAM, eGENS). The company's principals led development of IEEE C37.118 and IEC 61850 synchrophasor standards and have direct experience investigating the 1996 WECC and 2003 Eastern Interconnection blackouts.

EPG's customers are electric utilities, Independent System Operators (PJM, NYISO, CAISO, MISO, ERCOT), Reliability Coordinators, and international transmission operators — practically every major U.S. ISO plus deployments in Oman (OETC), India (GETCO, SRLDC), Jordan (NEPCO), and the Dominican Republic (ETED). The company reports installations at 50+ organizations across all three North American interconnections, with the GETCO India project (1,650 PMUs at 50 samples/sec) representing the world's largest WAMS deployment. Business model combines enterprise software licenses, professional services for deployment and training, and recurring training subscriptions via an online portal ($1,500/person for individual enrollment). Distribution is primarily direct enterprise field sales, supplemented by a technology partnership with Hitachi ABB Power Grids for international mega-deals and DOE-funded research collaborations with CERTS, PNNL, and several universities.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Hitachi Energy (formerly Hitachi ABB Power Grids): Hitachi Energy is a global leader in grid automation, ADMS, and PMU hardware, and is EPG's direct technology partner for the world's largest WAMS deployment (GETCO India). Comparability stems from overlapping grid-monitoring product portfolios and shared enterprise utility customers, though Hitachi operates at vastly larger scale across hardware and full ADMS/EMS suites.
• Siemens Smart Infrastructure (Grid Software): Siemens offers Spectrum Power ADMS/EMS and grid management software with synchrophasor capabilities to the same ISO and utility customer base as EPG. As a broad incumbent, Siemens competes via bundled solutions (control center, SCADA, ADMS) where EPG provides best-of-breed synchrophasor applications.
• GE Vernova (Grid Solutions): GE Vernova offers EMS, ADMS, and synchrophasor analytics (including PSLF simulation used by EPG customers) targeting the same utility and ISO market. GE competes as a full-suite incumbent while EPG provides complementary synchrophasor-specialized applications layered on top of GE's ecosystem.
• Schneider Electric (EcoStruxure ADMS / ArcFM): Schneider Electric provides ADMS, DERMS, and grid analytics (ArcFM, EcoStruxure ADMS) to utilities globally, with growing synchrophasor-adjacent functionality. Competes with EPG at the procurement level as utilities evaluate integrated grid management suites versus specialized synchrophasor platforms.
• Open Systems International (OSI / Emerson): OSI (now part of Emerson's Aspen Technology portfolio) provides monarch EMS and ADMS platforms to ISOs and utilities worldwide. Overlaps with EPG in the transmission control room buyer, where utilities choose between full EMS suites and specialized synchrophasor add-ons like EPG's RTDMS.

Direct peers

• Schweitzer Engineering Laboratories (SEL): SEL manufactures PMUs, protective relays, and synchrophasor applications (e.g., SEL-260, SEL-3378, synchrophasor vector processor) sold to the same utility and ISO customer base as EPG. Both companies target real-time wide-area monitoring and event analysis for transmission operators, making SEL one of the closest direct competitors in synchrophasor software and hardware.
• OSIsoft / AVEVA: OSIsoft's PI Historian is a primary data infrastructure integration partner for EPG's PhasorSmart and DataNXT platforms. Both companies serve time-series data management for utilities and industrial operators; while OSIsoft/AVEVA is broader, the integration with EPG and overlap in synchrophasor data archiving makes it a close direct peer in utility data infrastructure.
• Survalent Technology: Survalent provides SCADA, DMS, and OMS solutions for utilities (predominantly mid-market and municipal), competing for similar control room modernization budgets. While not synchrophasor-specific, Survalent increasingly bundles synchrophasor-adjacent monitoring features that overlap with EPG's lower-end PhasorSmart offerings.
• Arbiter Systems: Arbiter Systems manufactures PMUs (Model 1133A) and supporting software for synchrophasor applications in utilities and research institutions. Directly comparable to EPG in the synchrophasor hardware-software ecosystem, particularly in substation PMU deployments and university research labs.

Emerging players

• Power Factors: Power Factors provides renewable energy asset performance and analytics software to utilities and IPPs, overlapping with EPG's customer base in renewable-heavy ISOs like ERCOT and CAISO. While focused on asset management rather than synchrophasors, both serve the same data-driven grid modernization buyer.
