How to Sell to Solar Developers and Battery Storage Buyers

To sell to solar developers, start with the project and work outward to the people. Most US utility-scale solar and battery storage projects pass through three buyers.

1. The developer controls the project while land, permits, interconnection and the power contract get secured.
2. The EPC contractor (engineering, procurement and construction) designs the plant, buys most of the equipment and builds it.
3. The long-term owner, often an independent power producer or a utility, runs the plant for decades and buys what keeps it running.

Your job as a supplier follows the same order. Pick the projects most likely to get built. Work out which of these three buyers controls your purchase at that stage. Then reach the real title there through LinkedIn and email before the order is placed.

For 2026, developers have told the government to expect 43.4 GW of new utility-scale solar and 24 GW of new battery storage, according to the EIA.

I have no solar client case to show you, and I will not fake one. The method below comes from outbound work in other niches that sell to the same kind of buyer: the engineering, construction and energy companies that run big projects.

This guide is for equipment makers, subcontractors, engineering firms and service companies selling into US utility-scale projects. Rooftop solar, community solar and land leasing are left out.

Who actually buys on a utility-scale solar or storage project?

"Renewable energy" is an industry label. One person at one company signs your purchase order, for one project. Which company that is depends on the stage the project has reached.

The lines blur in practice. Some developers build their own projects, and some owners develop in-house. That is why a title alone never decides who goes on the list.

So start with your own history. When I open a new niche, I go through the past projects first and write down who actually approved each order.

Then I search for the titles that buyer carries in this niche, the ones on real project org charts, and skip whatever a database tags generically. Drop the catch-all titles: Assistant, Associate and a bare "manager", which on a solar EPC can be anyone from the person who signs your subcontract to an office coordinator.

Then I look at the companies already paying and find others built like them.

The decision rule:

• If your product gets specified during design, start with the developer's engineering team.
• If it gets bought during construction, start with the EPC's procurement and project leads.
• If it keeps a plant running, start with the owner.

Which solar and storage projects should you target first?

Start where the building is concentrated. In EIA's 2026 plan, Texas takes 40% of new utility-scale solar. Next come Arizona and California at 6% each, then Michigan at 5%. Storage leans even harder on one state: Texas holds 53% of planned battery capacity, or 12.9 GW.

One Texas project on that list, Tehuacana Creek 1, pairs 837 MW of solar with 418 MW of battery storage. For a storage supplier, that means solar developers belong on the list too.

The interconnection queue is the wider pool around that plan. Berkeley Lab compiled queue data from more than 50 grid operators. At the end of 2025 it counted about 8,200 projects actively seeking interconnection, with 1,312 GW of generation capacity plus roughly 749 GW of storage between them (Berkeley Lab, Queued Up 2026).

Historically, most of that capacity has not become a plant. Only 13% of the capacity that requested interconnection from 2000 to 2020 had reached commercial operation by the end of 2025.

So rank projects in three groups:

1. Projects in EIA's planned list for your target states. A developer has told the government it expects to bring them online.
2. Queue projects with visible progress. Look for an interconnection agreement, filed permits, or a named EPC.
3. Everything else in the queue. Treat it as background, and do not build outreach around it.

Then pick your territory. If you sell storage equipment or services, Texas comes first and it is not close. If you sell solar-only products and your reference projects sit in the Southwest, Arizona and California may be a better first ring than crowded Texas.

Whatever you pick, commit to it. I would rather see a supplier work one region and one buyer type for a full 12 months than hunt across twelve states at once. Before committing, check that the region holds enough accounts for the number of meetings you need. The arithmetic is in my market-selection order: closed deals, then market size, then geography.

When should suppliers approach each project phase?

Read the planning numbers for what they are. EIA's planned capacity comes from the Preliminary Monthly Electric Generator Inventory, built on Form EIA-860M. EIA calls these preliminary estimates that will be corrected, and says its figures are "not meant to be capacity commitments" (EIA-860M). A planned date tells you where to look. It promises nothing.

The pressure on developers is also uneven, and that shapes when they listen. These figures come from SEIA's Q3 2026 market report. SEIA builds it from bottom-up modeling, tracked component prices and industry interviews (SEIA Solar Market Insight Q3 2026):

• The safe-harbored pipeline (projects that began construction early enough to keep their tax credits) totals up to 240 GWdc (gigawatts of panel capacity).
• Projects that did not begin construction in time must be placed in service by December 31, 2027, or lose the credit window.
• Utility-scale contracting reached 4.9 GWdc in Q2 2026, down 8% from a year earlier. The leading states were Utah, Texas, Arkansas, Oklahoma and Washington.

In June 2026, Wood Mackenzie counted 457 solar and storage projects with permits pending, all vulnerable to delays or cancellations (Wood Mackenzie). For the credit rules themselves, read the official guidance or ask an adviser.

My reading: projects still waiting on permits will move slowly. Projects racing the 2027 date have a reason to buy early. Match your timing to that.

Here is the rule I would hand a sales team on day one. If a project has neither a permit nor an interconnection agreement, you are early: build the relationship and save the ask, unless your product shapes the design or the studies. If it has both, your message should name the project and request a short call.

How do you build a target list from project data?

Work from projects to companies to people, in that order:

1. Filter by geography. Take one or two states from EIA's planned list where your proof fits.
2. Pull the projects. EIA's monthly inventory tracks the status of proposed units at plants of 1 MW or more, which gives you project names, sizes and planned dates.
3. Add the queue projects. Berkeley Lab's dataset is built from grid operators' interconnection queues, so the queue of the operator covering your state is where these projects sit. Keep the ones that show progress, and tag each with its phase from the table above.
4. Map every project to companies. Record the developer, the EPC if one is named, and the owner if it differs. An EPC award usually surfaces in a press release, a county permit file or a post from the contractor's own team. If none is public yet, tag the project "EPC open" and work it through the developer. One company often appears on several projects, and that tells you which accounts deserve the most work.
5. Build rows per account. Each company gets one row, the projects attached to it, and the titles from the buyer table that fit the phase. A keyword search for "solar" returns installers, consultants and students, and few of them buy on utility-scale projects.
6. Segment before writing a word. Split by buyer type (developer, EPC, owner) and by phase. Each segment gets its own message, because a message written for everyone reaches nobody in particular.
7. Source and verify the contacts. Pull them from named data tools such as Apollo or LinkedIn Sales Navigator, never from scraped files of unknown age, and check that each address is valid before anything goes out, keeping the bounce rate below 0.5%. Bounced emails on a list this small burn the few accounts that matter. And no copy fixes a bad list.

The general list-building method, including a case where rebuilding the list turned a campaign around, is in my write-up on why the list matters more than the email.

What should your first message say to solar and storage buyers?

Ask for 15 minutes and nothing else. In a first message I sell the meeting and keep the service for the call. I also put proof straight into the email: a past client, a result, a case study the reader can check. And I keep it short enough to skim on a phone between site meetings, written the way a person talks.

For this market, good proof names three things: a comparable project size, the state or terrain, and what you delivered against the schedule. "We work with leading solar companies" proves nothing. A line like "finished piling on a 250 MW site in West Texas" would prove a lot, if it is true for you.

Take that proof from jobs you have already delivered, not from your brochure. Buyers check the reference you name, so it has to hold up when they pick up the phone.

A made-up example, from a piling subcontractor to an EPC construction manager:

Subject: Piling crews for your Texas solar build

Hi Maria, I saw your team is building the 300 MW solar and storage project outside Abilene, planned to come online next year. We recently finished pile installation on a 250 MW site in West Texas and can share the reference. If you are still lining up piling for this job, would a 15-minute call next week help?

That is about 60 words. It names one project, one scope and one piece of proof, and it asks one small question. It also matches the phase: construction is close, so the EPC is the buyer.

If you have no comparable US job, use your closest one by size and technology, and say plainly where it was.

How should email and LinkedIn work together here?

Let LinkedIn outreach open the conversation if the buyer is active there. The email then follows as a warm note to a buyer who already recognizes you from LinkedIn. Plan at least 5 to 6 touches across both channels; two messages followed by silence will miss most of the people you picked.

A sequence for one EPC procurement lead might run like this:

1. A plain LinkedIn invite that mentions the project or the region and sells nothing.
2. After they accept, a short LinkedIn message referencing their project.
3. The first email, using the message above.
4. A follow-up email with one new piece of proof, such as a photo of the finished site or a schedule chart.
5. A LinkedIn follow-up asking whether someone else handles piling on that job.
6. A last email that closes the loop politely and leaves the door open for their next project.

Give each step real time. In our campaigns, the reply that counts usually arrives around the third follow-up, as long as the follow-ups are spaced out rather than stacked.

When a reply points you elsewhere, such as "talk to our preconstruction team" or "procurement handles that," treat it as a warm introduction. Ask for the name, mention the referrer in your next message, and log it against the account.

Measure the campaign in this order: conversations started, then calls booked, then contracts. Conversations come first. Calls come out of conversations. Clients come out of calls.

What should renewable suppliers avoid when selling into this market?

Quoting the market back to the buyer. A development director tracks how many gigawatts are planned this year for a living, so opening with that number tells them nothing. The EIA and queue numbers are for choosing projects. Write about their project.

Pitching long-lead equipment after the site mobilizes. Big equipment is often ordered well before crews arrive, so ask the developer who holds that procurement contract. Once crews and equipment start arriving on site, sell what the EPC still buys there, or ask the developer which of its next projects is still in design.

Treating a queue entry as a purchase plan. Historically most queued capacity has not reached operation, as the Berkeley Lab figure above shows. A project with no permit, no interconnection agreement and no EPC is worth a LinkedIn connection, not a sequence.

Closing the account after one "no." A developer with four projects in your state can turn you down on one because the scope is already awarded and still need you on the next. Log the reason against the project, keep the account open, and come back when the next project reaches late development.

Start this week with the projects in your state that already have both a permit and an interconnection agreement, and find the person who buys your scope on each one. A team can run that for you, as my cold email agency does.

Following a project in an interconnection queue and unsure who signs? I can help work out whom to contact at the developer, just book a call.
