CogenS™ — CHP Module

The Ultimate Guide to CHP System Design

Combined Heat and Power (CHP), also known as cogeneration, is a cornerstone of modern, efficient energy strategy. Producing both electricity and useful thermal energy from a single fuel source, CHP systems can achieve efficiencies exceeding 80%.

Why CogenS™

From Spreadsheets to Engineering-Grade Precision

Historically, CHP feasibility analysis required complex, time-consuming spreadsheet models prone to error. Today, there’s a better way.

CogenS™ Design Tool is a free, powerful software platform that gives engineers, consultants, and facility managers the ability to conduct a comprehensive Combined Heat and Power feasibility analysis. Move beyond basic calculations and model the real-world performance, financial returns, and environmental benefits of your CHP project with engineering-grade precision.

Capabilities

Complete Technoeconomic Analysis for CHP Systems

CogenS™ empowers you to perform a complete technoeconomic analysis of a Combined Heat and Power system.

Model Different Prime Movers

Choose from 118+ CHP models across 24 manufacturers -- reciprocating engines (RICE), gas turbines, microturbines, and three fuel-cell types: phosphoric-acid (PAFC), solid-oxide (SOFC), and molten-carbonate (MCFC). Fuels include natural gas, hydrogen blends, and biogas.

Use Real-World Data

Pre-loaded TMY weather data, multi-tier utility tariffs (electric, gas, oil), and 8,760-hour reference load profiles for 30+ building types across 340+ cities. No external data collection needed.

Simulate Performance

Accurately forecast annual energy production, fuel consumption, and operational hours at intervals as low as 5 minutes.

Calculate Financial Viability

Generate NPV, IRR, TCO, and payback period with pre-loaded equipment CAPEX/O&M cost data, government incentives, and auto-converted financials in 40+ currencies.

Signature Features

Everything You Need for CHP Feasibility

Technoeconomic Engine

Perform a complete analysis combining technical performance with detailed financial modeling.

Real-World Inputs

Pre-loaded weather, utility tariffs, and building load profiles for 340+ cities, or upload your own data for a fully custom analysis.

Multiple Technologies

118+ CHP models from 24 manufacturers with real performance curves, part-load ratios, and degradation data. Reciprocating engines (RICE), gas turbines, microturbines, and three fuel-cell types: phosphoric-acid (PAFC), solid-oxide (SOFC), and molten-carbonate (MCFC).

Financial KPI Reporting

Automatically generate the key financial metrics (NPV, IRR, TCO) needed to justify your project to stakeholders.

DER Optimization

Tabbed optimization workflow that determines the optimal capacity mix and dispatch strategy for an integrated CHP + BESS + thermal energy storage (TES) + solar PV microgrid. Minimizes lifecycle cost across your specific load profile and tariff structure.

H2

Hydrogen Blending

Specify a hydrogen blend ratio for natural-gas-fired CHP units (RICE, gas turbines, microturbines, fuel cells). The platform auto-maps fuel properties so you can evaluate near-term H2 transition pathways alongside conventional natural gas operation.

Waste-Heat Capture Revenue (EaaS)

Model revenue from selling thermal output (steam, hot water, or chilled water via absorption) to a host facility under an Energy-as-a-Service contract. Revenue flows into the financial TEA report alongside electricity sales and avoided utility costs.

CHP Plant P&ID Diagram

Auto-generated P&ID schematic showing thermal mains, electric paths, absorption chiller branch routing, and multi-unit configurations. The diagram updates as you add or remove units (CHP, supplemental boilers, TES, absorption chillers) and ships with the print-ready TEA report.

Multi-Vendor Comparison

Compare multiple CHP manufacturers side-by-side with standardized technoeconomic metrics. Generate comparison reports showing NPV, IRR, payback, and energy cost differences across vendors.

Emissions Analysis

Quantify the carbon reduction benefits, supporting sustainability goals and regulatory reporting.

Why It Matters

Solving the Hardest Parts of CHP Design

Load Profile Matching

A successful CHP installation depends on accurately matching the system's electrical and thermal output to your facility's actual load profile, hour by hour, throughout the year. CogenS™ simulates this match with precision.

Complex Utility Tariffs & Incentives

Financial viability is intertwined with local utility rate structures — demand charges, time-of-use rates, standby fees — and government incentives. CogenS™ models these variables to give a true picture of economic performance.

Environmental & Resiliency Goals

CHP is a key technology for reducing greenhouse gas emissions and improving energy resiliency. By providing reliable on-site power, a well-designed CHP system can keep critical facilities operational during grid outages.
