Grid CapEx Assessments
Early insight into connection cost and grid losses for renewable energy projects.
Grid connection costs can make or break the economics of a renewable energy project.
Arra's Grid CapEx Assessments, prepared in collaboration with EnergyAI, give project teams an early technical view of potential connection options, indicative route distances, estimated connection infrastructure costs, and expected annual transmission losses.
Use them to screen opportunities faster, compare grid scenarios, and focus deeper diligence where it matters most.

What's inside each assessment?
Each Grid CapEx Assessment provides a clear, project-specific technical summary.
Optimal connection options
Review relevant grid connection scenarios where available.
Indicative route distances
Understand the estimated distance between the project location and selected connection points.
Connection CAPEX estimate
See an indicative breakdown of line, station, transformer, and connection-related cost assumptions.
Cost per MW
Compare connection scenarios using a normalized cost/MW view.
Transmission-loss estimate
Review estimated annual cable and transformer losses based on the assessed configuration.
Scenario comparison
Identify which assessed options appear most efficient from a cost and loss perspective.
A concise technical report your team can compare quickly.
Use report outputs to understand connection assumptions and compare likely cost and loss tradeoffs before deeper diligence begins.
Project screening
Built for faster project screening
Grid CapEx Assessments help renewable energy teams move from interesting project to worth deeper diligence more quickly.
They are designed for developers, investors, advisers, and asset teams who want a practical early-stage view of grid-related cost and loss assumptions before committing time and resources to detailed technical work.
Partner
Prepared in partnership with EnergyAI
EnergyAI brings specialist energy-data and infrastructure analytics capability to the assessment process. Arra and EnergyAI work together to prepare structured Grid CapEx Assessments for projects available on the arra platform.
The result is a concise technical report that helps users understand key grid connection considerations in a format that is easy to review, compare, and share internally.
Useful for teams that need early grid clarity
Developers
Screen projects before committing to more detailed technical work.
Investors
Compare connection scenarios across opportunities with a normalized cost view.
Advisers
Bring grid assumptions into early transaction conversations faster.
Asset teams
Share concise technical context with stakeholders during diligence.
