Renalfa
Renalfa was founded in 2017 in Sofia by Bulgarian industrialist Ivo Prokopiev, who also chairs Alfa Finance Holding. The firm operates as an integrated clean-energy platform spanning solar, wind, battery storage, green hydrogen, and electric mobility. From the start, Renalfa built both physical assets — its first major PV installations and wind parks — and the operating companies that deploy and service them. Renalfa allocates across renewable generation, energy storage, EV infrastructure, and green hydrogen. Its investment posture is project-heavy, moving from greenfield development through project finance and into operational asset management. The firm's main vehicle, Renalfa IPP, owns and operates a portfolio that passed 1 GWh of energy storage in operation and closed a €315 million HoldCo financing led by the European Bank for Reconstruction and Development (per the firm, 2025). Renalfa Solarpro Group functions as an installer and innovator for PV, BESS, and wind — it completed a 9.3 MWp self-consumption PV plant for Apollo Tyres in Hungary and a 2 MWp plant for Volkswagen in Poznan (per Renalfa, 2024). A joint venture with French investor RGREEN INVEST targets €800 million for regional IPP development in Eastern Europe, with €200 million already committed (per the firm, 2025). The firm also partnered with Eurowind Energy on the Tenevo Hybrid project, Bulgaria's first hybrid renewables scheme. Renalfa runs three operating companies that double as deployment channels: Eldrive, its EV charging network, received a €40 million loan from the European Investment Bank in 2024 to expand in Bulgaria, Lithuania, and Romania; Spark operates an EV car-sharing fleet; and a green hydrogen unit aims to build four plants with 400 MWe of electrolysis capacity. The group's physical footprint includes the Vetrocom Wind Farm near Kazanlak and the Landmark Centre Sofia commercial property. Its pipeline extends to 1.8+ GW of projects and 963 MW/3,570 MWh of battery storage capacity. Alongside the infrastructure buildout, Renalfa trades 4.5+ TWh of clean energy annually and signed the region's first corporate green PPA with A1. Renalfa's architecture differs from a typical infrastructure fund because it controls the entire value chain — from installation through trading to fleet operation — while financing projects through dedicated vehicles and lender clubs rather than blind-pool funds. Prokopiev's background as a founder of Bulgaria's main employer association, KRIB, and former chairman of the Bulgarian Industrial Association gives the group a regulatory proximity uncommon for independent developers. The firm is not a family office managing inherited wealth; it is a founder-led investment group that earns and redeploys capital through operating businesses and project finance.

Frequently asked questions
Who runs investment decisions at Renalfa?
Founder Ivo Prokopiev sets strategy as Chairman and CEO, with operational management split across the platform's units. Konstantin Nenov and Ivan Nenkov lead Renalfa Solarpro Group, the installation and innovation arm. Major financing decisions run through joint venture partners — RGREEN INVEST co-controls Renalfa IPP alongside Renalfa, and Eurowind Energy is a direct co-investor in the Tenevo Hybrid project.
How does Renalfa source proprietary deal flow?
Renalfa originates most projects through greenfield development rather than competitive auctions. Its in-house engineering unit, Renalfa Solarpro Group, scouts sites, designs PV and BESS installations, and builds them for third parties like Apollo Tyres and Volkswagen — a pipeline that feeds Renalfa IPP's acquisition funnel. The firm's early presence in Bulgaria, plus Prokopiev's relationships through employer and industry associations, gives it visibility into Eastern European energy infrastructure before broader processes launch.
Is Renalfa structured as a family office or a traditional asset manager?
Neither. Renalfa is a founder-led investment group that operates through three lines: an asset-heavy independent power producer (Renalfa IPP, with RGREEN as JV partner), an installation and innovation company (Renalfa Solarpro Group), and a clean energy trading desk. It does not raise blind-pool funds or manage third-party capital on a discretionary basis; it co-invests alongside strategic partners in project vehicles.
What is Renalfa's posture on co-investments alongside external GPs?
Renalfa acts as a principal, not an LP. Its main co-investors are strategic operating partners — RGREEN INVEST (France) in Renalfa IPP and Eurowind Energy (Denmark) in the Tenevo Hybrid project. Lenders include development finance institutions: the EBRD led Renalfa IPP's €315 million HoldCo club financing, and the EIB provided €40 million to portfolio company Eldrive for EV charging expansion.
Which sectors does Renalfa explicitly avoid?
Renalfa operates exclusively within the clean energy and electrification complex. It has no disclosed activity in fossil-fuel generation, traditional infrastructure (toll roads, airports), or financial services beyond project finance. Even its real estate holdings, such as Landmark Centre Sofia, appear incidental rather than a standalone property strategy.
How are Renalfa's philanthropic and operating structures separated?
Philanthropy runs through the Cedar Foundation, a separate legal entity focused on education and employment for people with intellectual disabilities in Bulgaria. The foundation is not funded from Renalfa's renewable energy cash flows in a disclosed earmarked structure; Ivo Prokopiev supports it personally and through his wider business interests.
What does Renalfa's green hydrogen strategy involve, and how serious is the commitment?
The firm launched a dedicated hydrogen business unit aiming to develop four green hydrogen plants in Bulgaria with a combined 400 MWe electrolysis capacity, each designed for 43 tons of daily output. The unit is still in early development — Renalfa frames it as a natural extension of its wind, solar, and storage portfolio, built on the same development-and-finance model it uses for utility-scale renewables (per Renalfa, 2025).
