About this event
Intersolar & Energy Storage North America – IESNA Midwest
Overview
IESNA Midwest (Intersolar & Energy Storage North America – Midwest) is a focused conference and expo event dedicated to the solar and energy storage ecosystem. Positioned in the Midwest market, the event brings together clean energy innovators, industry practitioners, and decision-makers to explore the latest technology, discuss policy and market developments, and build meaningful connections across the renewable energy value chain.
According to the event’s official information, the next edition takes place from June 14-16, 2027 at the Donald E. Stephens Convention Center in Rosemont, IL. The event format includes both conference programming and an exhibition, with multiple days of presentations, updates, networking opportunities, and hands-on training alongside an expo showcasing innovations in solar.
The event is described as formerly known as the Midwest Solar Expo, and it continues to provide a platform for solar + storage professionals to gain insights, share best practices, and connect with peers across the industry.
What to Expect on the Ground
IESNA Midwest is built for attendees who want more than static product browsing. The event combines:
- Conference content: cutting-edge presentations and learning opportunities for solar and energy storage professionals.
- Policy and market updates: time set aside for state-level changes and evolving trends that affect project development and deployment.
- Networking and peer learning: structured opportunities to meet clean energy leaders, practitioners, and collaborators.
- Hands-on training: practical training sessions intended to help professionals apply new knowledge and approaches.
- An exhibition: a marketplace-style environment where attendees can meet solution providers and explore innovations across solar.
Overall, the event is designed to support learning, decision-making, and relationship-building across solar and (where relevant to the broader IESNA series) energy storage and integration themes.
Why Attend IESNA Midwest
The event’s “Why Attend” positioning focuses on practical outcomes. Attendees typically come to:
- Explore innovative products and solutions that can support deployment and growth in the clean energy sector.
- Examine state-level policies and market trends so teams can plan effectively and understand regulatory direction and local market dynamics.
- Meet and learn from clean energy leaders and peers who are actively shaping solar and storage adoption.
- Take hands-on training to deepen operational competence and technical understanding—particularly valuable for teams who need actionable knowledge.
For event research and planning purposes, IESNA Midwest stands out as an industry-focused convening point where educational programming is paired with an expo experience. That combination generally attracts professionals who influence vendor selection, partnerships, project development, and technology adoption decisions.
Who Typically Participates (Audience & Buyer-Relevant Roles)
While individual attendee categories are not fully enumerated in the supplied source text for the Midwest page, the event is clearly positioned as a clean energy industry gathering. In practice, events built around solar innovations, policy updates, networking, and training usually draw the following buyer-relevant participant groups:
- Clean energy developers and project teams seeking solutions to move projects forward.
- Technology and component providers offering solar-related products and systems that integrate with broader grid and energy needs.
- Energy storage stakeholders interested in the role of storage in reliability, optimization, and project performance (aligned to the broader IESNA “energy storage” umbrella).
- Utilities and distributed energy ecosystem participants that evaluate market-ready offerings.
- Commercial and community solar leaders focused on scaling deployments and improving economics.
- Engineering, operations, and implementation teams looking for practical knowledge, best practices, and supplier relationships.
- Policy-aware professionals who attend to understand state and market trend implications.
- Manufacturing and supply chain participants supporting system availability, procurement planning, and technology readiness.
For attendee-list research purposes, the strongest buyer signals typically come from job functions aligned to project decisions, procurement, partnership building, and technical evaluation rather than purely informational attendance. This is the category of attendees most likely to convert event discussions into vendor selection, pilot programs, or contracted work.
Where the Show Happens (Location Context + Local Market Relevance)
The event is held at the Donald E. Stephens Convention Center in Rosemont, IL, United States, from June 14-16, 2027. Rosemont is a major convention destination serving the Chicago metro region, which generally increases accessibility for Midwest-based companies and decision-makers.
Because the event is explicitly framed as a Midwest-focused convening, it is expected to be particularly relevant to organizations with operational footprints, commercial development pipelines, or policy engagement needs in the central U.S. solar and storage market.
Core Themes & Program Focus
The event page emphasizes a clean-energy agenda centered on solar innovation and the practical application of industry knowledge. The following themes are consistently aligned with what attendees come to learn and act on:
- Solar product and solution innovation showcased through expo participation.
- Energy storage-informed decision contexts under the broader Intersolar & Energy Storage North America positioning.
- State-level policies and market trends that impact project timelines, economics, and market readiness.
- Networking and peer learning to support partnerships and collaboration.
- Hands-on training intended to translate knowledge into operational capability.
- Industry connections across companies, professionals, and clean energy operators.
In addition, the official page text indicates the event offers three days of presentations, policy updates, networking opportunities, hands-on training, and an exhibition showcasing the latest solar innovations.
Event Structure (Conference + Expo)
IESNA Midwest is structured as a combined conference and expo experience. Attendees can move between educational sessions and expo interactions, enabling:
- Evaluation cycles: learn about trends and technology, then validate offerings with vendors during expo time.
- Relationship building: connect with peers and solution providers in an industry-forward setting.
- Action planning: take insights from policy and market content into planning and procurement conversations.
For stakeholders planning attendance, this format typically supports both short-term engagement (meet providers, see products) and longer-term outcomes (follow-ups, partnerships, pilots, or contracts).
How We Can Use This Event for Deep Research & Buyer Targeting
If the goal is deep research analysis on events and conferences, IESNA Midwest is a strong candidate because it sits at the intersection of technology innovation, policy, and market deployment in the solar and energy storage ecosystem. This usually enables buyer segmentation based on:
- Procurement and deployment decision influence (teams that evaluate vendors and implementation approaches).
- Technical evaluation functions (engineering and implementation specialists who compare solutions).
- Commercial and project leadership roles (those who drive project pipeline decisions).
- Policy and market intelligence involvement (professionals who align strategy with regulatory direction).
- Supply chain and manufacturing-related participation (organizations supporting system availability and scaling).
To refine the “best buyer fit” with high precision, we would tailor buyer targeting to the exact category of solutions your client provides (for example: solar components, installation services, monitoring platforms, energy storage solutions, EV-adjacent charging infrastructure, manufacturing/supply chain products, or training/education enablement).
