Interlock Power AdvisoryFor developers, operators and site-selection teams
You found the land. Now find the megawatts.
Interlock gets large loads connected to the grid: data centers, fabs and electrified plants. We tell you how much power a site can really get, how long it will take, and what it takes to get it sooner.

Power, not land or fiber, now decides where large projects go.
Utilities are receiving requests for more load than their transmission systems were planned to carry. Studies take longer, upgrade costs arrive late, and a site that looked ready on a map can turn out to be five years from service.
Most teams learn this after the land option is signed. Interlock’s job is to find it out first, and then change the answer where the physics and the tariffs allow.
“The utility’s first letter is an opening position. It is rarely the fastest path.”
Three stages, each with a decision at the end.
Secure
Load request strategy, study scoping, and negotiation of facilities and service agreements.
Deliver
Owner’s representation through construction, commissioning and ramp schedule.

§ 01 ServicesSix practices, one team from screen to energization
Six practices, one accountable team.
Most clients start with a screen. About a third of screened sites move forward, and we stay with them through energization.
Fixed-fee screens. Retainers after that.
A site screen is a fixed fee, credited against a Secure engagement if you proceed. Secure and Deliver work is billed on a monthly retainer tied to milestones, not hours.
We do not take success fees contingent on utility decisions. It keeps our advice honest when the right answer is to walk away from a site.
§ 02 IndustriesWhere large loads are coming from
Different loads, different leverage.
A 300 MW campus and a 40 MW fab face the same utility with very different bargaining positions. We plan around the one you actually have.
§ 03 Case filesSelected engagements
What changed because we were there.
Each file shows the utility’s first answer, what we did, and where the project landed.

§ 05 TeamFormer utility planners, regulators and developers
We used to sit on the other side of the table.
Our partners have run transmission planning groups, written tariffs and negotiated service agreements for developers. We know what a utility can say yes to.
§ 06 FAQQuestions from first calls
Before the first call.
We already have a utility letter. Why screen again?
A capacity letter usually reflects today’s system and today’s queue. We test it against queued load ahead of you, planned upgrades and the tariff rules that decide cost allocation, which is where most schedules slip.
Do you work with the utility or against it?
With it. Utilities want load that pays for itself and does not threaten reliability. Our work is structuring requests so they can say yes faster, through phasing, flexibility commitments and funded upgrades.
Can you help if we have not picked a market yet?
Yes. Site selection teams often bring us a long list. We narrow it by power availability before anyone spends money on land or entitlements.
How confidential is a screen?
We work under NDA and never contact a utility about a specific site without written approval. Early screens use public data and our own models only.
What if the answer is no?
Then you will know in three weeks instead of eighteen months, and the screen fee is the cheapest thing you will spend on that site.
