RPX rebrands, adds BaaS
Solar Power Accelerator rebranded itself as RPX and introduced customized AI plus Battery‑as‑a‑Service offerings aimed at heavy transport electrification. Packaging batteries as a managed, subscription‑style asset shifts procurement questions toward total cost of ownership, SLA for capacity and data integration across fleets. (prnewswire.com)
A Swedish company that started in rooftop solar is now selling something closer to a trucking utility: power, software, and batteries bundled together for electric freight fleets. On April 10, 2026, Solar Power Accelerator said it had changed its name to Renewable Power Accelerator, or RPX, and shifted its focus to Europe’s heavy-duty transport market. (prnewswire.com) The company was founded in early 2023 to help commercial and industrial property owners in Sweden add rooftop solar and sell surplus electricity under power purchase agreements. RPX says demand for that original model cooled as it pivoted in late 2024 toward electric mobility infrastructure. (prnewswire.com, solarpwr.se) The new pitch is aimed at the hardest part of road electrification: heavy trucks that need large batteries, high-power charging, and tight route planning. The U.S. Environmental Protection Agency says trucking companies are already weighing how electric trucks change daily operations as more heavy-duty models reach production volumes. (prnewswire.com, epa.gov) Battery-as-a-Service means the fleet does not buy the battery pack like a normal piece of equipment. It pays for battery capacity as an ongoing service, which turns a giant upfront purchase into a contract with performance terms. (prnewswire.com, zenobe.com) That changes the buying question from “What does the battery cost on day one?” to “What does this route cost over five years?” The International Energy Agency’s 2025 Global EV Outlook flags total cost of ownership for electric heavy-duty trucks as one of the key variables shaping adoption through 2030. (prnewswire.com, iea.org) It also changes what a fleet manager negotiates. Instead of mostly haggling over purchase price, the contract starts to look like a phone plan or cloud-computing deal, with service-level agreements for usable capacity, uptime, charging access, and data feeds into dispatch systems. (prnewswire.com, zenobe.com) RPX is adding customized artificial intelligence software on top of that battery service. In practice, that usually means software that watches routes, charging windows, electricity prices, and battery health so a fleet can decide which truck charges when and where. (prnewswire.com, nlr.gov) The timing is not random. A 2025 study in Applied Energy found that total cost of ownership for electric trucks is already comparable with diesel in some smaller and short-distance segments, and projected broader parity if battery prices keep falling. (sciencedirect.com, nature.com) The catch is that battery economics are still messy for lenders and operators because resale values, degradation, and replacement timing are hard to model. A 2024 CALSTART explainer said battery-electric truck components could retain 15% to 25% of a truck’s initial value by year five, but financiers still lack much historical resale data. (calstart.org) That is why this rebrand is really a financing story wearing an energy logo. RPX is betting that fleets will adopt electric heavy transport faster if batteries feel less like buying an engine and more like subscribing to a guaranteed power service. (prnewswire.com, iea.org)
