What Byom does

Byom S.r.l. is a Rome-based Italian investment and consulting company founded in 2009 that operates primarily in the renewable energy and infrastructure market. The firm is organized around three service pillars: (i) energy services covering development of photovoltaic, wind, and BESS (battery energy storage) plants, asset management of renewable energy fleets, and technical due diligence for investors and lenders; (ii) energy community and self-consumption advisory, delivered principally through the FusionCER joint venture with Amaranto Holding Group (established 2021), which structured the first incentivised Renewable Energy Community (CER) in Italy at Vitulano and now runs more than 22 CACER configurations; and (iii) financial, accounting, tax, and corporate administration services for industrial clients and investment funds, managing a 40-company portfolio with combined production value of €66M. Key long-tenured advisory mandates include Asterion Fund (since 2019), GAM SGR / Clean Energy One (since 2018), Finint SGR / Copernicus Fund (since 2010), Tirreno Power, Herambiente Servizi Industriali, Libeccio SRL, and Matrix Renewables.

Byom's go-to-market is B2B direct enterprise engagement with industrial operators, companies, and investment funds in Italy, supplemented by event-driven demand generation at the KEY – The Energy Transition Expo and content marketing via its website and LinkedIn. Revenue is generated through professional services: advisory retainers, transaction and due diligence fees, asset management contracts (including a ~300 MW development portfolio managed for Matrix Renewables), and accounting/tax/administrative mandates. The firm owns, jointly and in partnership, approximately 80 MWp of operational photovoltaic and wind capacity and has launched a ~900 MWp pipeline of proprietary and third-party development since 2021. Pricing is not publicly disclosed; engagements are customized and quote-based.

The underlying technology stack is not disclosed; service delivery is expertise-led rather than software-led, with no proprietary AI/ML disclosed products or platform. The team's core asset is its personnel — over 20 professionals with 200 equivalent years of combined experience in industrial, energy, infrastructure, and consultancy sectors — supported by leadership including Managing Partner/CEO Massimiliano Salvi, Massimiliano Checchi (Investments and Operations), Giorgio Mingoli (Special Projects), and CFO Cristina Rastelli. Owner Massimiliano Salvi is also disclosed as Co-Owner & Founder.

Expansion highlights6 records

Broad incumbents

• ERG S.p.A. Large Italian renewable energy operator and asset manager with significant wind and solar capacity. Comparable as a client-counterpart and a benchmark for Italian renewable asset management, though ERG is a broad incumbent vs. Byom's boutique advisory model.
• Mott MacDonald: Global engineering and advisory firm with a strong Italian renewable energy practice in owner's engineering, technical due diligence, and lender's advisory. Comparable on the technical due diligence and project advisory dimensions of Byom's business.
• Enel Green Power: Italy's largest renewable energy developer and operator, with a captive asset management practice. A broad incumbent that both competes with and acts as a counterpart to boutique firms like Byom in the Italian market.
• Falck Renewables (now PLT Energia): Italian renewable energy developer and asset manager. Comparable to Byom as a competitor and as a target customer for development/asset management services; both operate in Italian wind and solar development.
• AFRY (formerly Pöyry): European engineering and advisory firm with deep renewable energy consulting and asset management expertise across Europe. Comparable on the financial/technical advisory and asset management dimensions of Byom's services.

Others

• Terna Energy Solutions: Italian TSO and adjacent energy services provider involved in grid integration and storage. Comparable as an ecosystem participant that Byom's BESS and storage development work must interface with, though not a direct advisor competitor.

Direct peers

• CESI S.p.A. Italian energy consulting and engineering firm working with utilities, developers, and investors on renewable energy project advisory, grid studies, and technical due diligence. Comparable to Byom on the technical advisory side of the Italian renewables value chain.
• Alerion Clean Power: Italian renewable energy operator focused on wind and solar asset management and development. Comparable to Byom's asset management and development practice, particularly for wind projects where Byom manages the Libeccio SRL portfolio.
• RINA: Italian engineering, certification and advisory firm with a significant energy and renewables practice. Directly comparable because it provides technical due diligence, owner's engineering, and asset management advisory to renewable energy investors and developers in Italy, the same value chain Byom serves.

Regional players
