What OptiStudio Is?

OptiStudio is INSUS’s industrial AI optimization platform designed to operate alongside existing plant automation infrastructure to optimize complex operational variables in real time.

Who It Helps

It serves energy-intensive manufacturers and utility operators- such as power plants, chemical producers, cement manufacturers, and seawater reverse osmosis (SWRO) desalination facilities- that manage high-cost, physically constrained operational loops.

What business outcome it delivers

OptiStudio reduces energy consumption, lowers overall operational costs (OpEx), stabilizes production quality, and cuts emissions through AI-generated setpoint recommendations without requiring a rip-and-replace overhaul of the plant’s Distributed Control System (DCS).

Executive Summary: Bridging the OT Optimization Gap

Industrial facilities running energy-intensive assets face high power tariffs, tight operational constraints, and strict quality requirements. Traditional automation tools manage baseline stability but lack the dynamic multi-objective capability needed to optimize real-time energy efficiency across continuous, variable inputs.

OptiStudio bridges this gap by deploying an advisory AI layer alongside existing operational technology (OT). It continuously ingests historian data, runs agentic AutoML and Bayesian optimization models, and provides supervisory setpoint recommendations to control room operators. Every output is subject to physical reliability validation and human-in-the-loop oversight to ensure zero disruption to plant safety or core DCS logic.

Across energy-intensive sectors, this approach delivers operational cost reductions of up to 10–18% (and utility cost savings of 30–40% across broader efficiency initiatives), stabilizes production parameters, and reduces carbon footprints while requiring zero upfront capital expenditure (CapEx) under INSUS's Gain-Share commercial model. Target industries include process manufacturing sectors such as Cement, Chemical Processing, Utilities & Desalination, Mining, Steel, District Cooling, and Petrochemicals.

The Core Challenge in Industrial Energy Optimization

Industrial facilities suffer from fragmented data sources, unutilized historical records, and manual operational adjustments that fail to adapt to real-time tariff and process fluctuations, directly increasing energy expenses.

Process environments incur unnecessary expenses due to structural inefficiencies across their operational architecture:

  • Siloed Historians: Critical process parameters are archived in isolated databases (e.g., OSI PI, Aspen IP.21) without continuous, cross-functional modeling.
  • Disconnected Data: Quality lab results, real-time telemetry, and energy grid tariffs remain unintegrated, delaying economic adjustments.
  • Tribal Knowledge: Shift operators rely on manual "rules of thumb" or static Standard Operating Procedures (SOPs), leading to inconsistent shift-to-shift performance and conservative safety buffers that consume excess power.
  • Fluctuating Energy Prices: Real-time variations in power tariffs or renewable availability are rarely integrated dynamically into control-room decisions.

This failure to model complex interactions dynamically forces operators to over-design processes- running pumps, kilns, or compressors above optimal energy baselines simply to protect quality margins.

Why Traditional Automation Falls Short

Standard control architectures (like APC and DCS) prioritize base-loop stability over dynamic, multi-variable economic optimization, leaving energy efficiency opportunities untapped.

  • Why APC isn't enough: Advanced Process Control relies heavily on deterministic linear models. When feedstocks, ambient conditions, or equipment wear drift, APC matrices require expensive, manual re-tuning by specialized control engineers.
  • Why dashboards aren't enough: Business intelligence dashboards show that energy was wasted past-tense, but they leave the operational response entirely to operator guesswork during live shifts.
  • Why historians don't optimize anything: Plant historians store billions of time-series data tags, but act strictly as passive data repositories rather than active optimization engines.

The Solution: What is OptiStudio?

OptiStudio places business outcomes—power reduction, emissions abatement, and cost minimization—ahead of technical feature sets. Rather than forcing a costly infrastructure overhaul, OptiStudio functions exclusively as an external, multi-objective advisory engine next to the DCS.

Core Engine Capabilities:

  • AutoETL: Ingests raw time-series sensor data from legacy OT platforms, automatically cleaning, unifying, and structuring tag feeds into single-source-of-truth analytical tables.
  • Agentic AI & AutoML: Automates feature engineering and model selection to dynamically adapt to shifting plant operational states.
  • Bayesian Optimization: Solves multi-objective trade-offs simultaneously (e.g., minimizing power usage while preserving total volumetric output and product spec boundaries).
  • Digital Twin Simulation: Simulates candidate recommendations within a virtual representation of the process asset prior to dispatch.
  • Reliability Gates: Enforces hard boundary rules, physical safety constraints, and asset operational ranges so no invalid setpoint is ever generated.
  • Human Approval Interface: Presents recommended adjustments to shift operators alongside clear, SOP-linked explainability metrics. Direct automated write-back to the PLC/DCS is explicitly blocked by design.

  1. Connect Historians: Non-intrusive integration reads live operational tags directly from existing plant infrastructure (e.g., OSI PI, Aspen IP.21, SCADA).
  2. Clean Data Automatically: AutoETL parses noise, fills missing data values, normalizes parameters, and aligns disparate timestamps automatically.
  3. Build Optimization Models: Multi-objective Bayesian algorithms map active process variables against economic, energy, and throughput constraints.
  4. Simulate Recommendations: Digital twin modules run continuous scenario checks to calculate expected power savings and process stability outcomes.
  5. Reliability Validation: Algorithmic gates verify that recommendations remain strictly within defined safe operating envelopes and equipment design limits.
  6. Human Approval: Recommendations populate the operator interface with reasoning context; control room personnel retain final execution authority.
  7. Continuous Learning: Closed-loop feedback ingests real-world performance results post-adjustment, continuously refining model precision over time.

AI Safety & Governance

Feature importance rankings provide transparent visibility into process drivers (power_consumption and pump_speed), supporting industrial explainability requirements.

Is AI safe to deploy in mission-critical process industries?

Yes, because OptiStudio isolates its AI models within a supervisory advisory layer, enforcing physical constraint gates and keeping control-room operators strictly in charge of execution.

Industrial leadership frequently cites operational safety and risk mitigation as top prerequisites for software deployment. OptiStudio is engineered around explicit safety guardrails:

  • Human-in-the-Loop Architecture: The AI functions strictly as a decision-support advisory system. Recommendations require human review before any change impacts the plant floor.
  • No Direct PLC Control: Automatic write-back into direct control loops is structurally prohibited by system architecture, preventing autonomous system overrides.
  • Reliability Gates: Physics-based constraints enforce operational boundaries (e.g., maximum pressure limits, temperature thresholds, vibration tolerances) to block out-of-spec actions.
  • Audit Trail & Compliance: Every recommended setpoint, operator action, rejection reason, and resulting plant behavior is logged for regulatory and internal audit requirements.
  • Explainable AI (XAI): Rather than outputting "black-box" numbers, recommendations include context detailing why an adjustment was suggested and how it aligns with established plant SOPs.
  • Cybersecurity Compliance: Designed to comply with IEC 62443 standards and enterprise IT/OT segregation requirements, protecting core control networks against external vulnerabilities.
