Direct peers

• Svea Solar: One of the largest residential and commercial solar EPC companies in Sweden, offering rooftop and ground-mount installations. Direct competitor to Alstra Energy in the Swedish solar EPC market, particularly for commercial and industrial customers.
• OX2: Stockholm-based large-scale renewable energy developer with operations across the Nordics and Europe, developing utility-scale solar and wind parks. Comparable in target market (utility-scale renewable EPC and development) and customer base (power producers, investors).
• Nordic Solar: Denmark-headquartered solar PV developer building and operating utility-scale solar parks across the Nordics. Closely comparable as a Nordic-focused solar park developer targeting similar investor and utility off-takers.
• Better Energy: Danish developer and EPC of large-scale solar parks across Northern Europe, with a focus on ready-to-build project development. Directly comparable in business model (utility-scale solar development and EPC) and Nordic geography.
• Soltech Energy Sweden: Swedish solar installer and EPC group active in commercial and industrial solar across Sweden. Direct peer in the Swedish C&I solar market with overlapping customer segments and similar service offering.

Broad incumbents

• Vattenfall: Swedish state-owned integrated utility with growing solar generation portfolio across Sweden and Europe, plus distribution and grid operations. Overlaps with Alstra on the utility-scale solar generation and grid-services dimensions but operates a much broader energy portfolio.
• E.ON Sweden: Large integrated energy company operating in Sweden with electricity distribution, solar, and energy solutions for commercial and industrial customers. Comparable customer base and overlap in solar/storage and grid services, but operates across a much wider portfolio.
• Fortum: Nordic integrated energy company with utility-scale solar development, battery storage pilots, and grid services across Sweden and Finland. Comparable on the utility-scale solar and battery storage dimensions, though much broader in scope.
• Solar Energy UK member firms (e.g., Banks Renewables / RWE): Large European energy developers and EPC contractors (such as RWE) building utility-scale solar and storage across Europe. Comparable as scaled competitors with project finance and EPC capabilities targeting the same hyperscale and data-center customer segments.

Regional players

• Ellevio: Sweden-focused electricity distribution operator managing significant grid infrastructure. Adjacent rather than directly competing; comparable as a Swedish energy infrastructure player that Alstra would interact with on grid-connection and frequency-regulation services.
