Utah-based rPlus Energies Lands New $650 Million-Plus Financing Package for Idaho Solar Project

The new Blacks Creek funding extends a larger capital-raising run that has turned Salt Lake City-headquartered rPlus into one of the most consequential renewable energy developers in the West.

19 March 2026 — Salt Lake City-based rPlus Energies has secured more than $650 million in new debt facilities, along with tax equity backing, for its Blacks Creek Energy Center, a 400-megawatt alternating-current / 520-megawatt direct-current solar project in Ada County, Idaho.

The debt package was led by Santander Corporate & Investment Banking and KeyBanc Capital Markets, while Santander also provided a tax equity financing commitment for the project.

As framed by rPlus CEO, President, and Co-Founder, Luigi Resta, this newest funding stands as "another major milestone" for the company.

“This project represents another major milestone for rPlus as we continue to invest in large‑scale, homegrown energy across the American West,” Resta said. “Santander and KeyBanc are strong partners, and we’re pleased to work with them to deliver a project of this scale and importance.”

On its face, this is clearly a major Utah-focused financing announcement.

But for Utah Money Watch readers, the bigger story is what this latest raise says about rPlus Energies itself.

rPlus is no longer just a Utah company with an ambitious renewable energy pipeline.

Rather, rPlus is increasingly a large-scale Western energy platform, a firm headquartered in Salt Lake City that is repeatedly attracting institutional capital to finance, construct, own and operate utility-scale generation and storage projects.

That distinction matters.

In the renewable energy business, plenty of developers can assemble a project pipeline on paper.

However, far fewer prove they can repeatedly turn that pipeline into financed, construction-ready infrastructure backed by large banks, tax equity investors, and platform capital providers. 

So far, rPlus Energies has built a track record that increasingly places it in that latter category, and the company’s recent capital history helps explain why.

A Look Back to Look Forward

In February 2024, Sandbrook Capital committed up to $460 million in platform equity to rPlus Energies, alongside continued support from Salt Lake City-headquartered Gardner Group, which formed rPlus as a subsidiary in late 2018.

At the time of that $460 million funding announcement, the companies said the investment would help advance a development pipeline of more than 15 gigawatts spanning solar, wind, battery storage and pumped storage hydropower, while also supporting a longer-term own-and-operate strategy.

That was followed in July 2024 by another landmark transaction as rPlus announced it had landed more than $1 billion in construction debt financing for its Green River Energy Center in Emery County, Utah.

That project includes 400MW of solar generation and 400MW / 1,600 megawatt-hours of battery storage (aka, 1.6 gigawatt or 1.6GW), a project which rPlus described as a key step in its evolution as an independent power producer.

Then came (as reported by Utah Money Watch in December 2024), combined financings of over $300 million for rPlus, specifically

🔹 A $179 million construction debt facility for Pleasant Valley Solar 2 in Ada County, Idaho, and

🔹 a separate $125 million corporate letter of credit facility secured with Deutsche Bank.

According to our research, the $304 million financings of last December mean that, in total, rPlus had raised nearly $1.9 billion in 2024 alone to support its more than 1.2 gigawatts under construction and the addition 15GW rPlus has announced it has in development.

This week's new Blacks Creek financing now adds another major layer to that capital stack.

It also fits into a broader strategic expansion in Idaho.

The rPlus Idaho Play Seen from a Utah Perspective

Although rPlus Energies is clearly Utah-headquartered company, the firm is not a Utah-only firm.

For example, in November 2025, rPlus Energies announced that it had acquired Blacks Creek Energy Center and Bluebird Solar in Ada County, Idaho, together representing 900MW of new solar and storage capacity. 

Blacks Creek, which rPlus acquired from Qcells, included 400MW of solar, plus a 200MW battery storage phase. 

Bluebird, which rPlus acquired from Mission Clean Energy, included 200MW of solar and 100MW of storage.

At the time of that November 2025 announcement, rPlus explained that its four Ada County developments represented more than $1.4 billion in planned investment and more than 1.2GW of solar and storage capacity.

That point is important because it reframes the rPlus announcement made this week.

Contextually, Blacks Creek is not a standalone project financing dropped into the middle of nowhere.

Instead, it is part of a larger regional buildout that has become one of the company’s most concentrated development clusters outside Utah.

The timing also fits a bigger conversation unfolding in Utah.

Since October 2024 and the Utah Office of Energy Development launch of its Operation Gigawatt initiative, Gov. Spencer Cox has repeatedly stated his goal of doubling the state’s power production over the coming decade as Utah responds to rising electricity demand tied to population growth, electrification, artificial intelligence, data centers and other energy-intensive industries.

Now clearly Blacks Creek is obviously an Idaho project.

But the ongoing financing success of rPlus underscores a related point for Utah readers:

rPlus Energies, one of the state’s leading homegrown energy developers, is already helping build the kind of large-scale generation capacity that the broader Operation Gigawatt push says the region increasingly needs.

The Rest of the Story

This week's rPlus news release notes that Pleasant Valley Solar 2 is expected to reach commercial operation in spring 2026.

Additionally, the firm stated that the rPlus-developed projects in Ada County that are operating, under construction or contracted now represent nearly 1GW of energy capacity.

Without question, the energy demand driver is both significant and notable.

Specifically, rPlus, has stated that its Blacks Creek Energy Center will deliver solar electricity to Idaho Power’s grid and support Meta’s public commitments tied to power use at its Kuna, Idaho data center, while also serving additional Idaho Power load needs.

Contextually, such a framework gives this new $650 million in debt facility monies for continued Blacks Creek development even more heft beyond project finance alone.

In fact, when you figuratively connect-the-funding-dots tied to rPlus, they place the company squarely at the intersection of utility procurement, grid growth and the rising electricity demands of hyperscaler data infrastructure.

From my perspective, that is a meaningful and powerful place to be ... no pun intended.

Across the American West, the energy conversation has shifted from broad talk about decarbonization to a much harder question:

Who can actually deliver large amounts of new generation and storage onto the grid, on a financeable basis, and at the pace required by utilities and large energy users? 

For its part, rPlus Energies is clearly positioning itself as a leading Utah-linked answer to that question, an inference that can be drawn from the company’s deal flow, project scale, and stated mission.

Wrapping it all Up: The "Poppa P Perspective"

Its own public positioning reinforces that view. 

For example, rPlus says it focuses on developing, financing, constructing, owning and operating large-scale renewable generation and electric storage projects across the United States, and that its portfolio includes solar, battery, wind and pumped storage hydro.

The company also says it now has more than 1.5GW of developed assets in operation or under construction.

AUTHOR'S NOTE: One point of precision worth making.

The company’s release states that rPlus Energies secured “over $650 million in debt facilities, along with tax equity financing commitments” for Blacks Creek.

When read carefully, however, that wording suggests the debt facilities alone exceed $650 million, with tax equity on top of that.

Because the company did not publicly break out the exact tax equity amount, the cleanest and safest framing for today's writeup is that rPlus secured more than $650 million in debt facilities (plus tax equity backing), rather than assigning a single all-in total to the full capital stack.

Preciseness aside, the bottom line is this:

The newest rPlus Energies financing matters not only because it is large, though it clearly is. It matters because it extends a now-familiar pattern.

From platform equity to construction debt, and from to corporate credit facilities to project acquisitions, rPlus keeps assembling capital at meaningful scale.

Such an approach suggests a sophisticated approach to monies: Call it the rPlus Financial Stack.

And with this latest Blacks Creek funding package, the Salt Lake City-headquartered company has given itself another marker in what is becoming one of Utah’s more intriguing, and arguably important, long-range energy financing stories.

Put simply, the new $650 million-plus financing is the headline.

The deeper story is that rPlus Energies keeps proving it can raise real money for real energy projects across the West.
