Frequently Asked Questions

RE+ is the evolution of SPI, ESI, and Smart Energy Week. Originally developed by the nation’s leading solar energy organizations to engage the business community, the Smart Electric Power Alliance (SEPA), and the Solar Energy Industries Association (SEIA), RE+ reflects an ongoing entrepreneurial approach to renew best practices across the clean energy landscape as the marketplace evolves. 

Registration to RE+ gives you access to solar, energy storage, hydrogen, EV infrastructure, grid edge technology, and wind power education sessions and exhibiting companies, along with multiple days packed with networking events.

Over time, the renewable industry has evolved—battery costs have dropped, transportation and electrification has changed, and state-level mandates and policies are building towards a carbon neutral future. SPI stayed ahead of this collective shift and has diversified over the years to accommodate emerging trends and complimentary technologies, solidifying its place in the market as the harbinger of the greater renewable energy market. The name change reflects a commitment to providing industry-wide networking, education, and exhibition opportunities that drive a renewable energy future. 

Our flagship event, Solar Power International generates success for energy professionals and the global solar industry. SPI sets the standard for solar events as the fastest growing and largest energy event in North America as recognized by Trade Show Executive and Trade Show News Network. SPI has also been among the Gold 100 for ten years running and has previously been named “Best Use of Technology” and the “Stickiest Show Floor” by Trade Show Executive for the innovative ways in which attendees stay engaged .

With costs continuing to decline, energy storage deployment is rapidly expanding and Energy Storage International (ESI) paves the way for greater integration between the energy storage, solar, and distributed energy markets. As the largest energy storage event in North America, ESI features hundreds of exhibitors and thousands of attendees drawn to energy storage technology and applications each year.

RE+ Events restricts exhibitors and other companies from hosting or participating in competing or conflicting events or activities that occur during official show hours. Exhibitors violating this policy will be subject to cancellation of their booth without refund and may not be invited to participate in future exhibitions. Booth Personnel are not permitted to promote the exhibiting company outside the contracted exhibit space. All marketing must remain within the contracted exhibit space. Marketing materials may not be placed on conference tables or other areas that are not within the boundaries of the booth, both inside and outside of the exhibit hall. Show management reserves the right to remove individuals or discard display materials that do not comply with these guidelines. Please note that while RE+ Events   has a zero-tolerance policy regarding suitcasing. Any attendee who is observed to be soliciting business in the aisles or other public spaces, or in another company's booth, will be asked to leave immediately.

What is suitcasing?
Suitcasing is a business practice in which unethical companies will gain access to an event by obtaining some type of event credential (attendee badge, expo-only badge, etc.) and then solicit business in the aisles or other public spaces used for the conference. This practice skirts the support of the organizer and the industry. Attendees that sell to exhibitors or other attendees within the exhibit hall, but don't purchase an exhibit to do so, are suitcasing. Typically, suitcasers approach people in the public areas of the show, such as registration and food-service areas, or aisles, and hand out brochures or other marketing collateral. This includes the hotels. This is expressly prohibited at most shows since again, these people are poaching the attendees that exhibitors have paid to see.

What can you do?
Attendees can report any observed violations to the exhibits manager, other RE+ Events  staff, or conference security. The exhibits manager will investigate all complaints of suitcasing. RE+ Events   recognizes that suitcasing may also take the form of commercial activity conducted from a hotel guest room or hospitality suite, a restaurant, or any other public place in proximity to our event. For the purposes of this policy, suitcasing violations may occur at venues other than the exhibition floor and at other events. It is for this reason RE+ Events   staff must be informed of any hospitality suites and expressed consent must be given prior to the event.
