Most Stranded Projects Were Not Bad Projects.

They were good projects on the wrong bus, filed into the wrong cluster, or priced before anyone checked the upgrades.

Keentel Engineering screens candidate sites, points of interconnection and queue positions before the land, deposits and study fees are committed. We use advanced interconnection modeling and market analytics, then apply the judgment of engineers who perform system impact, EMT, protection and substation work every day. You get a ranked, defensible answer in days, and one firm to carry the winning site from screen to energization.

01

Where to Build

Nodal price, congestion, nearby competing projects, regional load growth and distance to viable POIs, ranked site by site.

02

What It Will Cost to Connect

Network upgrades, cost allocation, constraint drivers and attrition scenarios for generation in every U.S. RTO and ISO.

03

Whether the Grid Can Serve the Load

Withdrawal headroom, upgrade exposure and phased-ramp scenarios for data center and large-load sites.

High-voltage electrical transmission infrastructure

Send your candidate sites or queue position, project type and MW. We return a scoped fee and schedule, usually within a few business days.

Site & Market Screening and Generation Cost Screening

Where a project should go and what the interconnection will likely cost, answered before the application, the deposit or the land option.

Renewable energy project site
01

Site & Market Screening

A candidate site is only as good as the node it settles at and the bus it connects to. We screen sites against the market and grid conditions that decide revenue and risk, then rank them on one consistent basis.

Nodal price profile. Historical price level, shape and volatility at the settlement node, by hour and season, and how the site compares with nearby hubs.
Congestion exposure. Monthly and annual congestion patterns, binding constraints near the site and the direction of basis risk.
Competing development. Projects in the queue or under construction nearby, their size, technology and stage, and what they mean for headroom and cost sharing.
Load growth. Regional demand trends and where new large loads are landing, which shapes future pricing and upgrade need.
Transmission access. Distance to candidate substations and lines, voltage class, and whether a tap, a new switching station or a radial line is realistic.
Engineering flags. Short-circuit strength, weak-grid indicators, right-of-way constraints and anything our study engineers expect to drive cost later.
Outcome A ranked shortlist with a one-page summary per site: price and congestion context, POI options, competing projects and the red flags to check before land control.
Best for: early-stage developers, land and origination teams, data center site selectors, portfolio planners.
Transmission grid infrastructure
02

Generation Interconnection Cost Screening

ALL U.S. RTOs
For solar, wind, storage and hybrid projects, we model the RTO cluster study process to estimate the network upgrades a project is likely to trigger and the share it is likely to carry.

Upgrade identification. Thermal and voltage constraints the project is likely to trigger or worsen under the applicable study criteria.
Estimated upgrade cost. Planning-level cost of the upgrades, using the RTO's cost basis and our own substation and line experience.
Cost allocation. The project's likely share of each upgrade, based on its contribution to the constraint.
Attrition scenarios. How cost and allocation move as other projects in the cluster withdraw, so you can see best case, expected and worst case.
POI and size sensitivity. Alternate buses, MW sizes and technology mixes to find the configuration with the lowest exposure.
Stay-or-withdraw support. For projects already in a cluster, a view of exposure ahead of the next decision point and deposit.
Outcome An upgrade and cost-allocation summary with the constraints driving it, attrition cases, recommended POI and size, and the questions to raise in the RTO scoping meeting.
Best for: developers preparing applications, projects in active clusters, teams facing a withdrawal or deposit milestone.
Applies To

Utility-scale solar · Onshore wind · Standalone and co-located BESS · Hybrid plants · Repowering and capacity additions · Portfolio origination

Large-Load Headroom Screening and Queue Due Diligence

Whether the grid can actually serve the load, and whether a queue position is worth what someone is asking for it.

Data center infrastructure
03

Large-Load & Data Center Headroom Screening

For data centers, industrial expansions, hydrogen and electrification projects, power availability is the schedule. We screen candidate sites for how much load the grid can take today and what it would take to serve the rest.

Withdrawal headroom. Load the grid can serve at candidate substations and buses without triggering upgrades, under normal and contingency conditions.
Upgrade exposure. Planning-level upgrades and cost to serve the full requested load where headroom falls short.
Multi-site comparison. Candidate sites and markets ranked on headroom, cost and timeline on one consistent basis.
Phased ramp scenarios. Initial, interim and full build-out loads, so energization can start before the last upgrade is in service.
Co-location and on-site generation. How on-site generation, storage or a co-located plant changes the net withdrawal and the upgrade picture.
Utility engagement prep. The load profile, single-line concept and questions to bring to the utility's load interconnection process.
Outcome A headroom map of candidate sites, upgrade exposure for the full load, a phased ramp recommendation and a package ready for the first utility meeting.
Best for: hyperscale and colocation developers, powered-land developers, industrial and manufacturing expansions.
Professional engineering due diligence
04

Queue Due Diligence

Before you buy, finance or sell a project, you need an independent view of the interconnection position, which is often the largest unknown in the valuation.

Position review. Queue number, cluster, study phase, milestones met and milestones still ahead.
Study document review. Feasibility, system impact and facilities study results read by engineers who write those studies.
Cost exposure. Current upgrade allocation, sensitivity to attrition and the realistic range still ahead.
Schedule risk. Remaining study phases, upgrade in-service dates and their effect on the commercial operation date.
Technical red flags. Model gaps, ride-through or EMT issues, POI configuration problems and anything likely to come back in review.
Buy-side and sell-side. Independent reports for acquirers, lenders and tax equity, or pre-sale packages for sellers.
Outcome A due diligence memo with a risk-rated summary, cost and schedule ranges, red flags and recommended conditions or next steps.
Best for: investors, IPPs, lenders, tax equity and M&A teams, and developers preparing a project sale.
Applies To

Hyperscale and colocation data centers · Powered land · Industrial and manufacturing · Hydrogen and electrification · Project acquisitions, financings and sales

Screen to Study

The screening work carries forward into formal studies, engineering and design.

What a Screen Tells You

Relative ranking.

Which sites, POIs and sizes carry the least risk, on one consistent basis.

Planning-level cost range.

The likely order of magnitude of upgrades and your share of them.

The drivers.

Which constraints, contingencies and nearby projects are behind the number.

Where to look harder.

The questions to take into the RTO or utility scoping meeting.

What a Screen Does Not Replace

The formal study.

RTO, transmission owner and utility studies set the final requirements and costs.

A guarantee.

Results are engineering estimates. Queue changes, model updates and new projects move them.

Detailed design.

Final upgrade scope and cost come from facilities studies and engineering design.

Plant-level compliance.

EMT, ride-through and protection studies still follow for the selected project.

One Team, One Model Lineage

The engineer who flags a weak-grid bus in the screen is on the team that later builds the EMT model for it. Assumptions, POI choices and red flags are documented once and carried forward, not rediscovered.

How the Work Runs

WHY CLIENTS BRING THIS TO US

01

The Answer Arrives Before the Commitment

Screening happens while land, deposits and study fees are still decisions, not sunk costs.

02

Engineers Read the Results

Numbers are reviewed by people who run system impact, EMT and protection studies, so anomalies get caught.

03

Built for One Client

Every screen is run for one client only and never resold or reused for another.

04

No Handoff Gap

The team that screens the site designs the interconnection, so assumptions carry straight through.

Screen the Grid Before You Commit

Send your candidate sites or queue position, project type and MW. We return a scoped fee and schedule, usually within a few business days.

Market Coverage

Generation Interconnection Cost Screening

Nationwide, all RTOs/ISOs: PJM · MISO · SPP · ERCOT · CAISO · NYISO · ISO-NE. Cluster-based upgrade and cost-allocation screening for solar, wind, storage and hybrid projects.

Site, Market and Large-Load Screening

Nationwide: PJM · MISO · SPP · ERCOT · CAISO · NYISO · ISO-NE, plus the Southeast and West non-RTO utilities. Tell us the location, utility or balancing area.

Common Reasons a Site Disappoints

Chosen for land, not the grid. Cheap acreage next to a congested or weak bus.
Load ramp assumed, not studied. Full load planned for day one when headroom supports a phase.
Nearby projects ignored. Competing queue positions share, or claim, the same headroom.
Price risk missed. Congestion and basis that erode revenue after COD.
Single-scenario cost. Upgrade estimates that assume no one else withdraws, or everyone does.
No path to the formal study. A screen that cannot be carried into the application package.

When to Screen

Before Land Control

Rank parcels before options and leases are signed.

Before Filing

Pick the POI and size with the lowest upgrade exposure.

Before Each Decision Point

Re-check exposure ahead of deposits and withdrawal windows.

Before Close

Price the queue position before an acquisition or financing.

Scoping Inputs

Site coordinates or queue number · Project type and MW · POI options if known · Load profile or ramp plan for large loads · Decision date
