What Pearl Street Technologies does

Pearl Street Technologies is a Pittsburgh-based software company that develops applications and platforms for power grid analysis, with a specific focus on mitigating the U.S. utility-scale interconnection backlog. Its two core products are SUGAR™ (Suite of Unified Grid Analyses with Renewables), a power flow engine that adapts circuit simulation methods originally developed at Carnegie Mellon University for billion-transistor electronic design automation to deliver robust steady-state convergence for transmission planning, and Interconnect®, a developer-facing scenario analysis and risk assessment platform offering on-demand injection capacity maps, automated model building, thermal analysis, and cost allocation across user-defined scenarios. Together, the products reduce engineering analysis time by up to 200x and have been used to model 2,000+ generation and storage projects across 500+ GW of ISO-contracted capacity.

The company operates a B2B SaaS model with subscription-based pricing (annual billing for Interconnect®, multi-year enterprise contracts for ISO/utility deployments of SUGAR) and a direct enterprise sales motion supplemented by self-serve web access to the Interconnect platform. Customer segments are vertical: transmission providers (ISOs and utilities, anchored by MISO and SPP), renewable project developers, M&A analysts, and policy advisors. Distribution is primarily direct enterprise field sales targeting ISOs, augmented by content marketing, industry event presence (RE+), and earned media in clean energy publications. Pearl Street was founded in 2018, secured NSF SBIR funding in 2018 and 2020, raised a seed round led by Pear VC with VoLo Earth Ventures in 2022, and was acquired by Enverus (backed by Hellman & Friedman) in March 2025, after which it operates as a part of Enverus while continuing to serve customers under its existing brand and products.

The market opportunity is structurally driven: a 2.4+ terawatt interconnection queue across U.S. ISOs, combined with FERC Orders 2023 and 2023-A mandating interconnection process overhauls, has created a compliance-driven procurement window in which Pearl Street's installed position at two of the largest U.S. transmission providers (MISO and SPP) provides regulatory tailwinds and a defensible reference-customer base for further ISO expansion.

Core offering

Pearl Street Technologies develops cloud-based software for power grid interconnection analysis. Its SUGAR™ platform serves transmission providers by running thousands of complex power flow scenarios in minutes using proprietary circuit simulation methods, replacing legacy software that requires days or weeks. Its Interconnect® platform enables project developers, M&A analysts, and policy advisors to run interconnection studies and assess system upgrade costs and constraints for proposed generation projects.

Product overview

Pearl Street Technologies offers a unified platform of two integrated software solutions: SUGAR™ and Interconnect®. SUGAR™ serves as the core power flow engine for transmission providers, providing industry-leading convergence robustness for grid analysis and accelerating interconnection study processes by up to 200x. Interconnect® is the developer-facing application that leverages SUGAR™ to deliver scenario analysis, risk assessment, and cost allocation capabilities. Both products work together to help stakeholders overcome the interconnection backlog that has created a 2.6+ terawatt queue of pending renewable energy projects across U.S. ISOs.

Partnerships

Three partnerships are on record, tiered core.

• EnveruscoreStrategic or Co-development Partner · 1 March 2025Enverus, backed by private equity firm H&F (Hellman & Friedman), acquired Pearl Street Technologies in March 2025. The acquisition aims to enhance energy project interconnection processes and improve speed and efficiency of energy project approvals amid growing interconnection queues.
• MISOcoreStrategic or Co-development Partner · 1 August 2024In August 2024, MISO announced integration of Pearl Street's software automation solutions to accelerate interconnection study processes. This collaboration represents the largest-ever investment in interconnection study automation made by a transmission provider. By mid-Q1 2025, a first-of-its-kind full automation system will be deployed to rapidly process DPP Phase 1 interconnection requests.
• Southwest Power Pool (SPP)coreStrategic or Co-development Partner · 1 January 2023SPP deployed SUGAR to automate interconnection study processes, following MISO's lead. SPP has used the software to clear more than 10% of the nation's interconnection backlog. David Kelley, VP of Engineering at SPP, provided testimonial noting significant time reductions from weeks to 30 minutes.

Broad incumbents

• Siemens PTI (PSS®E): Industry-standard power system simulation suite (PSS®E, PSS®SINCAL) used by most North American ISOs and utilities for transmission planning studies. Competes head-to-head with Pearl Street's SUGAR for power flow and interconnection study workloads, but as part of a much broader Siemens grid software portfolio.
• GE Vernova (PSLF / MAPS): Provides PSLF and MAPS, two of the most widely deployed power flow and production-cost tools used by North American transmission planners. Competes with Pearl Street on steady-state analysis and interconnection studies, anchored by an extensive installed base at US ISOs and utilities.
• Hitachi Energy (PSS®E / PSCAD / e-Mesh): Sells PSS®E (since the ABB acquisition) along with PSCAD and broader grid-software and -services offerings. Overlaps with Pearl Street on transmission planning and interconnection analysis as part of a much larger grid hardware and software portfolio.
• Energy Exemplar (PLEXOS): Provider of PLEXOS production-cost and capacity-expansion modeling software widely used by ISOs and utilities. Adjacent competitor — used alongside power-flow tools in interconnection and planning studies — and increasingly a substitute in integrated planning workflows.

Direct peers

• PowerWorld Corporation: Developer of PowerWorld Simulator, an interactive power flow and visualization tool widely used by transmission planners, ISOs, and educators. Most directly comparable to Pearl Street on power-flow simulation and is a likely substitute in ISO RFPs.
• GridUnity: Cloud-based interconnection and transmission planning platform used by ISOs and utilities to streamline queue management and study automation. Most direct competitor to Pearl Street's Interconnect® on the queue-management and developer-facing workflow.

Emerging players

• Kevala: Grid data and analytics platform that maps hosting capacity and DER interconnection potential for utilities, regulators, and developers. Overlaps with Pearl Street's capacity-map and queue-intelligence capabilities from an analytics rather than power-flow simulation angle.
• Camus Energy: Grid orchestration and DERMS software for utilities managing distributed energy resources. Adjacent competitor to Pearl Street in the grid-software SaaS category, with overlapping ISO and utility buyers even though the core use cases differ.
• LineVision: Provides dynamic line rating and grid-monitoring sensors and analytics for transmission operators. Thematic peer in grid-modernization SaaS for utilities; serves some of the same ISO and utility buyers as Pearl Street even though the underlying problem (line capacity) differs.
• PingThings: Time-series data platform for grid operators and utilities, focused on high-resolution sensor and SCADA data. Adjacent SaaS infrastructure competitor in the utility-analytics category and a potential partner or substitute for parts of Pearl Street's modeling stack.
