CHP & Cogeneration

When combined heat and power makes sense, sizing to heat demand, and assessing economic and carbon performance.

01CHP Fundamentals

  1. How CHP WorksEngine/turbine + generator produce electricity; waste heat recovered for heating/DHW.11 min
  2. CHP Technologies (Gas, Biomass)Reciprocating engines, microturbines, Stirling engines; pros and cons; typical sizes.10 min
  3. Efficiency Metrics & LossesElectrical efficiency, heat recovery efficiency, overall efficiency, stack losses.10 min
  4. CHP Fundamentals CheckQuiz on CHP operation, technologies, and efficiency.5 min

02Sizing & Integration

  1. Sizing to Heat Demand (Not Electricity)CHP should be sized to annual heat demand curve; oversizing = wasted electricity export.10 min
  2. Load Profile AnalysisThermal and electrical demand matching; seasonal variation; identifying steady base load.10 min
  3. CHP Integration with Boiler/ChillerHybrid operation: CHP for baseload heat, boiler backup for peaks; sequencing controls.10 min
  4. Sizing & Integration CheckQuiz on heat-demand sizing and system integration.5 min

03Economics & Carbon Assessment

  1. Cost-Benefit AnalysisCapital cost, fuel cost, electricity export revenue (or avoided grid purchase); 10-year payback.10 min
  2. Grid Connection & Export RevenueMetering, export tariffs (export price vs avoided import cost), DNO approval.10 min
  3. Carbon Payback & LifecycleManufacturing carbon, fuel carbon, electricity displacement; payback period.10 min
  4. Economics & Carbon CheckQuiz on CHP payback, export economics, and carbon assessment.5 min

04Capstone Project

  1. Capstone: CHP DiagnosticsHands-on: diagnose eight CHP call-outs — dumped heat, spark spread, low-value export, fouled heat exchangers, short-cycling and the carbon case — then calculate, verify and prescribe the fix.30 min
