Integrated Optimization for GHG Reduction RGGI Stakeholder Meeting NYC, New YorkFebruary 16th, 2005
NeuCo, Inc. • Boston-Based Software Company • Founded in 1997 • Market Leader in Combustion Optimization • Providing AI Solutions to Electric Power • Data to Knowledge to Action • Process Control to Enterprise Optimization • Running on >80 Large Fossil Generating Units • Fuel Efficiency Improvements from 0.5 – 2.5% • NOx Reductions from 5 - 25% • Developing/Demonstrating Integrated Optimization Suite
Customers El Paso Electric
ProcessLink Solutions for GHG Reduction • CombustionOpt • NOx and Heat Rate Reduction though Fuel & Air Management • PerformanceOpt • Heat Rate Reduction through Reduced Controllable Losses • MaintenanceOpt • Heat Rate Reduction through Reducing Maintenance-Related Inefficiencies • SootOpt • NOx and Heat Rate Reduction through Optimal Boiler Cleaning • DispatchOpt • Meeting electricity demand with the most efficient units
NEUCo Solutions & GHG Benefits • CombustionOpt provides reductions of 0.25-2.0% with simultaneous NOx reductions. • PerformanceOpt can add another 1.0-1.5% reduction. • SootOpt can provide an additional 0.5-1% improvement. • MaintenanceOpt, by identifying equipment degradation and efficiency losses, may dwarf other gains but won’t be demonstrated until late 2005. • DispatchOpt ensures most efficient mix of units for any overall electricity demand. • These products will also help users respond to existing and emerging competitive pressures in the face of fewer skilled operators and engineers.
Combustion Optimization • Lower NOx (5-25%) • Improved heat rate (0.5-2.5%) • Better control of CO, LOI, and opacity • Enhanced operator performance • More consistent operations • Advanced diagnostics • Lower post-combustion costs • Capital preservation

SootOpt • Two modules • Multiple zones, real time CFs • Flexible integration approach • Utilizes existing technology • Addresses global objectives
PerformanceOpt • Serves as bridge between physical and business optimizers. • Builds upon investment and field experience through EPRI and Black & Veatch. • Combines thermodynamics with inductive and expert systems technologies. • Collects, calculates and validates plant performance metrics. • Coordinates equipment level actions toward the unit goals of heat rate, emissions and capacity. • Advanced analysis and diagnostics tools support improved maintenance and remote diagnostics.
MaintenanceOpt • Exploits same underlying thermodynamic model and rule sets as PerformanceOpt. • Focuses on inefficiencies requiring maintenance actions to rectify. • Maintenance actions tend to have greater impact on efficiency than DCS-actuated controllable losses. • Integrates with all major CMMS platforms. • Advanced analysis and diagnostics tools support improved maintenance and remote diagnostics.
DispatchOpt • Use real-time cost modeling to optimize unit-specific production levels for aggregate MW commitments at any node. • Explicitly addresses start-up and shut-down costs. • Simulates optimal dispatch under any set of unit costs, operating parameters and market conditions. • Inductively forecasts demand and LMP on Day-Ahead and Hourly basis. • Ensures most efficient mix of units meeting any overall level of electricity demand.
