Set a new direction in energy and emissions planning

Quickly explore the energy landscape. Investigate an unlimited range of scenarios. Optimize to targets. Posterity Group Navigator™ Energy and Emissions Simulation Suite lets planners create flexible, realistic models to forecast how customer energy use and greenhouse gas (GHG) emissions respond to programs, technology, pricing and policy.

Finally, a better way than spreadsheets and simplistic models

Posterity Group Navigator™ incorporates over 20 years of modelling expertise into a powerful platform for: 

  • Integrated resource planning
  • Energy efficiency potential estimates
  • Demand side management (DSM) program planning
  • Policy impact analysis, and GHG emissions studies 

Analyze and explore alternatives instead of wrestling with your model


Access unprecedented processing power and easy to explore datasets

Posterity Group Navigator™ Energy and Emissions Simulations Suite enables complex, multi-variable modelling not possible with traditional approaches. It lets planners quickly explore the energy landscape, investigate an unlimited range of scenarios, optimize to targets and resolve vexing strategic challenges. All backed by Posterity Group’s expert energy and emissions consulting services.

  • Create flexible, realistic simulations of energy use and GHG emissions

  • Perform unconstrained scenario analysis and solution optimization

  • Communicate model dynamics with greater confidence

  • Dispense with unwieldy spreadsheets and simplistic econometric models

Perform complex analysis and sophisticated optimization

Posterity Group Navigator™ models annual energy consumption and GHG emissions, by region, rate class, block type (such as building, factory or ship) and energy end use. 

Detailed data from census and other government sources, utility customer data, end use surveys and research reports are compiled by a powerful processing engine to produce a comprehensive dataset available for scenario analysis. 

Every calculated value is stored and can be filtered and rolled-up for maximum flexibility of analysis and presentation using standard office productivity software.

Easy access to detailed, “high-resolution” datasets plus fast processing power, ensure the simulation is a powerful means of performing complex scenario analysis such as:

  • Load forecasting over time under a variety of demand growth, pricing, regulatory and technology adoption scenarios
  • Demand Side Management potential savings from efficiency and distributed resource measures
  • Peak demand impact
  • GHG emissions and reductions

As well, users can perform sophisticated optimization tasks such as:

  • Fuel switching in response to price signals
  • Substitution of a system-wide fuel (such as renewables) in specified amounts
  • Efficiency program spending within annual budgets

Explore in minutes rather than calculate for hours

Unlike cumbersome, error-prone spreadsheets and “black box” econometric models, Posterity Group Navigator™ uses actual customer data to create a rich, realistic model that can be easily queried and modified. Calculations that once took hours can be executed in minutes. This encourages exploration of the impact of variables, running scenarios to test assumptions and solving for optimization targets within specific constraints.

Because there’s always a clear line of sight between input data and the output dataset, planners have confidence in their results and can more effectively communicate the dynamics of their energy use model to stakeholders.

Explore and drill-down into the energy & emissions landscape


Detailed output data can be filtered across multiple dimensions and graphically presented to quickly answer questions and reveal deeper insights. With this flexibility and processing power, planners and analysts can spend more time thinking about opportunities rather than massaging data and manipulating spreadsheets. They can quickly answer stakeholder questions and easily explore a wider range of options.

Explore a Commercial Energy Consumption Scenario

Drill down from annual energy consumption in the most likely scenario to energy use mix by building type in 2028


Explore a Residential Emissions Scenario

Drill down from annual energy consumption in the most likely scenario to residential emissions reductions in 2038 for newer dwellings




Posterity Group Navigator™ is used by utility companies, government agencies, communities, industry associations, clean-tech companies, investors, and energy/carbon consultants to model and explore a wide range of energy use, efficiency, technology and GHG questions. 

Planners and decision-makers rely on its realistic forecasts and scenario simulations to inform capital plans, policy and program decisions and investments.

Utility Load Forecasting

Using Posterity Group Navigator™, utility resource, revenue and system planners can create an integrated model of service territories to estimate future load with greater precision and realism than can be done with typical econometric trending. It enables variation in load forecasts, impact of conservation programs and impact of policy changes to be considered within an integrated resource plan.

A major North American natural gas utility used Posterity Group Navigator™ to develop a load forecasting model for its ongoing Integrated Resource Planning (IRP) process.

“Data from a wide range of internal and external sources were assembled to run 3 core simulations and over 20 exploratory variations. The output data array was used to prepare tabular and graphical input for a Long Term Gas Resource Plan filed with the regulator and to respond during the Information Request (IR) process. Posterity Group Navigator™ has also been integrated into the utility’s Load Forecasting system and the output is being used to enhance its sophisticated system capacity planning."

Energy Efficiency Potential Estimation

With Posterity Group Navigator™, government policy planners and utilities can model energy consumption over time by building-type and end use. By applying energy efficiency improvement assumptions, planners can estimate potential savings to guide standards development, set energy and GHG emissions policy, and design efficiency programs. 

Natural Resources Canada (NRCan) modelled national energy savings and GHG reduction.

NRCan considered changing ENERGY STAR rating levels for residential windows, doors and skylights over a 20 year period. The comprehensive analysis included 22 regions, 6 fuels, 4 dwelling types, 7 vintages, 12 end uses and dozens of ENERGY STAR measures
