Load growth. Resource retirements. Transmission expansion. Policy changes. Fuel prices. Storage. Each assumption can reshape long-term market outcomes. But many organizations still face a tradeoff: ready-to-use forecasts with limited visibility into the underlying assumptions, or sophisticated models that require extensive preparation and workflow management.

Yes Energy Modeling gives utilities, developers, investors, and market participants a better way to understand what could happen before deciding what to do next.

Understand More Before You Decide

Start With a Transparent Market View.

Explore fundamentally modeled long-term market outlooks built on documented assumptions. Understand what is driving the results, not just the answer.

Test the Futures That Matter.

Change assumptions, run scenarios, and see how different choices reshape market outcomes. Scalable energy market simulation software makes broader scenario exploration practical.

Connect Resource and Transmission Planning.

Connect integrated resource planning with detailed power grid modeling. Evaluate capacity needs, resource portfolios, market operations, and transmission impacts from the zonal level through detailed nodal analysis, without stitching together disconnected tools.

Spend More Time Deciding.

Reduce the data preparation, exports, imports, and workflow handoffs that slow analysis. Bring model-ready data, forecasts, and simulation capabilities together so teams can focus on interpreting results and making decisions.

Model Portfolio and Market Futures at Scale.

Bring capacity expansion, production cost modeling, and embedded powerflow together in one modeling environment. EnCompass helps teams plan future resource portfolios and analyze how market and transmission conditions could shape outcomes across zonal and nodal markets.

Frequently Asked Questions on Modeling Solutions

What is power system modeling software?

Power system modeling software helps organizations analyze how changes in demand, generation, transmission, fuel prices, policy, and other assumptions could affect future market and grid outcomes. These platforms can combine energy market simulation, capacity expansion, production cost modeling, powerflow analysis, and scenario planning to support long-term decisions.

What is the difference between EnCompass and GridSite?

GridSite is forecast-led. It provides ready-to-use nodal market history, long-term forecasts, infrastructure intelligence, and benchmarking for teams evaluating sites, assets, and market opportunities.

EnCompass is modeling-led. It gives teams direct control over assumptions so they can build, modify, and run their own capacity expansion, production cost, and powerflow scenarios.

What long-term market forecasts are available in GridSite? The Nodal Forecast provides a 20-year outlook of hourly nodal prices. It includes three scenarios updated quarterly, with nodal LMP and marginal emissions results produced by the same model. Documented assumptions and methodology help users understand what is driving the forecast.

How does EnCompass support long-term energy planning?

EnCompass supports integrated resource planning, generation and transmission planning, portfolio strategy, resource adequacy, and regulatory analysis. It brings capacity expansion, production cost modeling, and embedded powerflow together so teams can evaluate how different assumptions affect resource needs, market operations, costs, and transmission outcomes.

Can Yes Energy support both zonal and nodal analysis?

Yes. EnCompass supports connected zonal and nodal modeling workflows, allowing teams to move between broader market planning and detailed grid analysis. GridSite provides ready-to-use nodal history and long-term forecasts for evaluating specific locations and assets.

How transparent are Yes Energy’s forecasts and models?

GridSite provides documented forecast assumptions and methodology, supported by quarterly analyst review. EnCompass gives modeling teams visibility into and control over model inputs, assumptions, and scenarios. This transparency helps users understand what is driving the results and explain their analysis to regulators, investors, lenders, and other stakeholders.

Can EnCompass support large-scale scenario analysis?

Yes. EnCompass is designed to run multiple simulations in parallel and make broader scenario exploration practical. Cloud-scale execution allows teams to move beyond a few base cases and investigate how combinations of load growth, resource changes, transmission development, fuel prices, policy, and other assumptions could reshape future outcomes.

Is EnCompass available in the cloud and on-premise? Yes. EnCompass supports both cloud and on-premise deployment. Cloud deployment enables scalable scenario execution, workflow automation, and easier collaboration, while on-premises deployment supports organizations that require greater control over their modeling environment.
