Origis Energy has entered a 20-year solar-plus-storage power purchase agreement (PPA) with Pioneer Community Energy, a not-for-profit Community Choice Aggregator (CCA) based in Rocklin, California. Under the agreement, Origis will deliver clean electricity and energy storage capacity from its new 65 MWac solar and 25 MW (100 MWh) battery energy storage system (BESS) project in Lost Hills, Kern County, California. Commercial operation of the project, named Chalan Solar + Storage, is scheduled for 2026.
Why did pioneer community energy partner with origis energy for its solar and storage needs?
The deal is part of Pioneer Community Energy’s broader strategy to expand its electricity service across 13 new jurisdictions. The Chalan project will provide the additional generation and storage capacity needed to meet the load requirements of this upcoming expansion, while supporting California’s Renewable Portfolio Standard (RPS) and broader decarbonization goals.
Pioneer Board Vice Chair and Rocklin City Councilmember Greg Janda said the partnership comes at an “opportune time” as the utility scales up its operations. The utility, which began serving customers in 2018, currently sources approximately 50% of its power from renewable resources and is seeking to improve both the quantity and reliability of clean energy in its portfolio as its customer base grows.
What are the technical and financial details of the Chalan solar + storage project?
The Chalan project includes a 65-megawatt alternating current (MWac) solar photovoltaic array, paired with a 25 MW / 100 megawatt-hour lithium-ion battery storage system. This configuration enables time-shifting of solar generation, storing excess power during the day and discharging during peak demand periods—an increasingly critical capability in California’s evolving grid environment.
While financial terms of the PPA were not disclosed, long-term utility-scale solar PPAs in California have recently settled in the range of $25–$45/MWh, depending on location, contract structure, and integration of storage. Based on this range, the 20-year agreement could potentially represent more than $100 million in contracted revenue over its lifetime for Origis Energy.
Origis Energy, a private renewable energy developer with over 3 gigawatts (GW) of solar and energy storage projects in operation or construction, will fully develop, build, own, and operate the Chalan facility. The project aligns with its strategy to deploy cost-competitive clean energy assets that can provide grid support and stability, especially in geographies with ambitious climate targets like California.
How does this agreement support California’s clean energy mandates?
The California Energy Commission (CEC) and California Public Utilities Commission (CPUC) have mandated aggressive clean energy procurement through 2030 and beyond. The CPUC’s Mid-Term Reliability procurement orders require load-serving entities like Pioneer to secure new clean energy resources, including storage-backed renewables, to replace retiring gas plants and the Diablo Canyon nuclear facility.
This mandate, along with the increasing frequency of climate-driven grid stress events such as wildfires and heat waves, has elevated the importance of integrated solar and storage projects. Pioneer’s partnership with Origis directly supports these efforts by ensuring resource adequacy and system reliability for its growing customer base.
The Lost Hills location in Kern County is also notable, as it lies within one of California’s most active renewable energy zones. With existing transmission infrastructure and high solar irradiance, Kern County has been a focal point for large-scale clean energy development. Chalan adds to a growing cluster of battery-backed solar projects helping to anchor California’s energy transition.
What is the broader market context for utility-scale solar and storage PPAs?
The Origis–Pioneer deal is emblematic of a broader surge in long-duration renewable PPAs across the U.S., particularly in states with high decarbonization ambitions. The U.S. added over 13 GW of utility-scale solar and nearly 5 GW of battery storage capacity in 2024 alone, with projections pointing to record growth again in 2025. California continues to lead both segments, driven by aggressive policy mandates and the maturity of Community Choice Aggregators like Pioneer.
This trend is also shaped by the ongoing implementation of the federal Inflation Reduction Act (IRA), which provides expanded tax credits for solar, storage, and clean energy developers, including investment tax credits (ITCs) that can be transferred or sold. Origis Energy is among the developers leveraging IRA incentives to deliver more competitively priced projects with enhanced economic returns.
From a procurement standpoint, utilities and CCAs are increasingly prioritizing hybrid projects that combine solar and storage, given their ability to deliver dispatchable, clean power that meets both resource adequacy and decarbonization needs. Analyst sentiment suggests that such projects now represent over 60% of all new PPA announcements in California, reflecting an evolution in clean energy procurement strategies.
How are investors and analysts viewing origis energy’s growth trajectory?
Although Origis Energy is privately held, the company has been actively scaling its footprint across the U.S. and Latin America through a mix of third-party PPAs, build-own-transfer (BOT) agreements, and merchant market plays. Its pipeline reportedly exceeds 20 GW, with a particular focus on solar-plus-storage and green hydrogen projects.
Market observers have described Origis as one of the “quiet consolidators” in the U.S. renewables space. The company’s ability to secure long-duration utility offtake agreements like the one with Pioneer is seen as a sign of strength in a capital-intensive, margin-compressed sector. Its expansion into storage-backed contracts also reflects its strategic pivot toward grid-interactive energy solutions rather than standalone solar assets.
The Pioneer deal may further elevate Origis’ positioning as a trusted utility-scale partner at a time when many project developers are struggling with inflationary pressures, permitting delays, and interconnection bottlenecks.
What are the next steps in the project timeline?
The Chalan Solar + Storage project is expected to complete permitting and begin construction in early 2026, with commercial operation targeted by the end of the same year. Development timelines for such projects in California typically range from 18 to 36 months, depending on environmental impact reviews, grid interconnection studies, and community engagement.
Given its location in Kern County—a region with favorable permitting frameworks and existing grid capacity—industry experts suggest Chalan is likely to proceed on schedule. Pioneer will begin receiving deliveries under the PPA upon the project’s commissioning.
From a customer perspective, the added clean power will enable Pioneer to maintain rate stability and meet growing demand without turning to carbon-intensive peaking resources. This is particularly important as the utility expands into jurisdictions that previously relied on investor-owned utilities for electricity.
How does this align with Pioneer Community Energy’s expansion strategy?
Founded in 2017, Pioneer Community Energy is a joint powers agency currently serving Placer and El Dorado counties, with active plans to expand into additional areas including Butte, Nevada, and Yuba counties. The expansion will bring Pioneer’s service territory to over 500,000 residents and businesses, more than doubling its current load.
To support this growth, Pioneer has been proactively seeking long-term clean energy contracts that provide both environmental and financial certainty. The agreement with Origis helps de-risk this expansion by securing dispatchable solar-backed power at a known cost structure, avoiding exposure to volatile wholesale power prices or spot market premiums during high-demand events.
Vice Chair Greg Janda emphasized that the partnership ensures Pioneer can deliver on its sustainability goals while maintaining reliability and affordability for its customers—a key consideration as energy costs remain top of mind for California ratepayers.
Analysts expect further solar-plus-storage partnerships in California’s CCA landscape
Industry analysts suggest that the Origis–Pioneer deal is likely a harbinger of similar agreements across California’s dynamic CCA ecosystem. With more than 10 million Californians now served by CCAs, and increasing regulatory pressure to procure firm, carbon-free resources, the demand for utility-scale solar-plus-storage contracts is expected to rise sharply through 2030.
Origis Energy’s growing portfolio of such projects positions it to benefit from this market tailwind, especially as CCAs seek long-term partners who can provide integrated development, construction, and operation services. Pioneer’s approach may also influence other CCAs to prioritize similar contracting structures that balance cost, sustainability, and grid reliability.
