Using configurable shift factor analysis and transmission modeling, Gransolar expanded early-stage screening from approximately 10–15 sites annually to hundreds of candidate locations across multiple markets.
Background
As utility-scale renewable development becomes increasingly competitive, developers are under pressure to evaluate more sites, move faster, and identify interconnection risk earlier in the process. For global renewable developer Gransolar, scaling early-stage site evaluation required more than public overlays and high-level market screening. They needed engineering-grade visibility into system capacity and power flow behavior to prioritize the strongest opportunities before investing deeper engineering resources. By integrating InSights into their workflow, Gransolar significantly expanded the number of sites they could evaluate annually, helping their team move from reviewing a handful of locations each year to screening hundreds of candidate sites across target markets.
About Gransolar
Gransolar is an international renewable energy company focused on the development, construction, and operation of utility-scale solar and energy infrastructure projects. With projects spanning multiple global markets, the company evaluates opportunities across evolving regulatory environments, land availability constraints, and transmission system conditions. As development competition intensified, Gransolar sought a more scalable way to evaluate grid feasibility and congestion risk earlier in the development lifecycle.

Challenge
Historically, early-stage site evaluation required stitching together multiple market intelligence and mapping tools to understand: regional pricing dynamics market attractiveness land positioning transmission congestion exposure However, understanding whether a site could realistically support new generation still required deeper engineering analysis. At the same time, increasing interconnection competition required the team to evaluate significantly more opportunities before committing to land negotiations, dispatch analysis, and formal interconnection studies.

Unlike generalized market grid intelligence platforms, InSights enabled Gransolar to evaluate hundreds of candidate sites each year using the same proprietary, engineering-grade power flow models EPE uses in formal grid studies, not public GIS overlays or disconnected datasets. giving the development team greater confidence before advancing sites into deeper analysis.
According to the Gransolar team, the ability to evaluate power flow behavior and system capacity early became a key competitive advantage in prioritizing candidate sites.

Key Outcomes
- Expanded Site Screening Capacity: Gransolar dramatically increased the scale of opportunities they could evaluate. Instead of limiting deep analysis to approximately 10–15 sites annually, the team can now efficiently screen and compare hundreds of candidate locations across multiple markets.
- Earlier Visibility into Deliverability Risk: Using InSights to evaluate system constraints and shift factor sensitivity helped the team identify congestion exposure and potential curtailment risk before advancing sites further into development. This allowed Gransolar to focus engineering resources and dispatch analysis on stronger candidate locations.
- Improved Development Efficiency: By incorporating engineering-grade intelligence earlier in the workflow, the team reduced time spent advancing lower-quality opportunities and improved confidence during land evaluation and project prioritization discussions.
