Arkansas Generator Interconnection Queue Update - Fall 2025

September 24, 2025 | Stacey Svendsen, Operations Director

Arkansas leads the region in renewable development interest. The state’s position in MISO South makes it a hub for solar, hybrid, and wind projects. Developers are pursuing projects at unprecedented scale, reflecting both resource quality and access to wholesale markets. Arkansas’ queue is dominated by MISO, with SPP adding a smaller share. The sheer volume of renewables in the pipeline underscores Arkansas’ position as a key renewables state in the Southeast.

Arkansas By the Numbers:

Solar: 27.8 GW (26.2 GW in MISO, 1.6 GW in SPP)
Wind: 3.0 GW (all in MISO)
Hybrid: 9.8 GW (9.2 GW in MISO, 0.6 GW in SPP)
Battery Storage (Standalone): 2.0 GW (1.25 GW in MISO, 0.77 GW in SPP)
Renewables Total: 42.6 GW
Gas: 1.6 GW (1.47 GW in MISO, 0.1 GW in SPP)

Powering Arkansas

The coming years will test our state’s electric grid. Powering Arkansas is a nonpartisan coalition of Arkansans united to engage and empower voices across The Natural State who support utility-scale renewable energy developments. Our mission is simple: accelerate energy growth in Arkansas by connecting people who understand that a modern, reliable grid requires local, scalable solutions.

If you agree that we need to move every available electron we can get onto the grid to build a future for Arkansas where energy is homegrown, reliable, and abundant, Powering Arkansas invites you to join us. This is about real progress, real collaboration, and real results. It's about lower bills, local jobs, and a more resilient grid for tomorrow. We can pursue practical policies that streamline permitting while encouraging investment in our rural communities.

Together, we will drive the energy future Arkansas deserves.

Challenge Misinformation

Powering Arkansas partners with communities across the state to counter misinformation about renewable energy and to support community leaders in crafting clear, practical language for advocating when wind or solar projects come to their areas.

Coalition Building

Powering Arkansas believes lasting change comes from uniting communities, policymakers, and industry partners to advocate for transparent, evidence-based renewable energy policies. By forming broad coalitions across the state, we advance practical, affordable power solutions that protect everyday Arkansans.
