Who is EnCompass designed for?

EnCompass is designed for organizations and teams responsible for long-term power system planning, market analysis, and infrastructure investment decisions.

Utilities use EnCompass to support integrated resource planning, capacity expansion, and fuel and emissions analysis, while also understanding how transmission constraints, congestion, and deliverability affect portfolio outcomes. Because zonal and nodal simulations live in one platform, planning teams can move beyond siloed IRP and transmission studies toward a more integrated system planning approach.

Transmission planners rely on EnCompass to evaluate congestion drivers, test transmission expansion options, and assess how new generation, retirements, or large load additions impact flows, reliability, and costs across the grid.

Developers, IPPs, and investors use EnCompass to evaluate generation and storage projects, assess basis and curtailment risk, identify binding constraints, and test sensitivities related to transmission upgrades, load growth, and policy changes. Nodal price formation and powerflow insights help inform siting, valuation, and acquisition decisions.

EnCompass is also widely used by consultants, cooperatives, regulators, and market participants who need a defensible, transparent modeling framework that supports scenario analysis, regulatory filings, and stakeholder review.

In short, any organization that needs to understand how generation, transmission, markets, and policy interact over time can benefit from EnCompass, especially those looking to replace disconnected tools with a single, integrated planning platform.

What capabilities does EnCompass have?

EnCompass is an integrated power market simulation and planning platform that combines zonal capacity expansion, production cost modeling, and nodal power flow modeling in a single system. It supports integrated resource planning and integrated systems planning through long-term portfolio optimization, fuel and emissions analysis, congestion and deliverability assessment, and zonal and LMP price forecasting across multi-decade planning horizons.

How does EnCompass differ from other power system modeling software?

EnCompass brings zonal capacity expansion, production cost modeling, and embedded nodal power flow together in one integrated platform.

EnCompass also supports single-pass co-optimization of energy, capacity, and ancillary services, flexible time resolution, and scalable deployment for broader scenario exploration.

What algorithm does EnCompass use?

EnCompass uses a security-constrained unit commit (SCUC) and security-constrained economic dispatch (SCED) to determine the least-cost solution to meet energy demand. SCUC determines when generators will be on or offline, while SCED determines how much energy is dispatched from online or available resources.

Can EnCompass run zonal and nodal analysis?

Yes, our power market simulation software conducts zonal and nodal analysis. Teams can evaluate long-term portfolio and market outcomes at the zonal level, then examine nodal prices, transmission constraints, congestion, and deliverability using a consistent modeling foundation.

Can EnCompass perform sub-hourly analysis?

Yes, EnCompass supports hourly and sub-hourly simulations, with time steps as short as one minute. This allows teams to evaluate ramps, reserves, renewable variability, fuel constraints, and short-duration storage behavior at the resolution their study requires.

Does EnCompass come with data, or do I use my data?

EnCompass can be configured with model-ready North American datasets, and customers can also incorporate their own data and assumptions. Available datasets can support zonal and nodal analysis across the Eastern, Western, and ERCOT Interconnections. Dataset contents and availability may vary by package and deployment

How does EnCompass support modeling at scale?

EnCompass is available as a fully managed cloud solution that allows teams to scale computing resources as their modeling needs grow.
