EPS readies first international credit rating and bond debut as Serbia’s power market shifts toward negative pricing

Elektroprivreda Srbije (EPS) is moving into a decisive phase where financing strategy and market rules are converging. Preparations for a first-time international credit rating by end-2026 are taking shape alongside structural changes in Serbia’s electricity system, with EPS signalling that it wants to fund its transition through capital markets rather than relying primarily on sovereign-backed borrowing and bilateral loans.

Negative pricing raises the stakes for revenue stability

The company’s bond plans land at the same time as a major shift in how electricity prices are formed. Serbia plans to introduce negative pricing on the SEEPEX day-ahead and intraday markets from May 2026, a step toward EU market coupling that also exposes EPS more directly to volatility. In a system long characterised by regulated pricing and dominant state ownership, negative prices represent a fundamental change in revenue dynamics—particularly as renewable generation penetration rises.

A credit rating becomes the gateway to international debt markets

EPS is seeking an international credit rating by end-2026, which management frames as a prerequisite for accessing international debt markets. The company’s approach marks a departure from earlier funding patterns and points toward a more diversified capital structure anchored in bond issuance. Management has indicated that green bonds would be the primary entry point, but only if EPS can build a sufficiently large and bankable pipeline of renewable energy projects.

€27bn of capex through 2050 reshapes the funding model

The investment scale is central to why capital markets are becoming less optional. EPS estimates capital expenditure requirements of approximately €27bn through 2050, covering renewable generation, grid upgrades and system balancing infrastructure. The company says internal cash flows are under pressure—linked to legacy thermal operations and regulated tariffs—and that domestic banking capacity, while meaningful, cannot absorb the full financing burden without creating concentration risks.

Quasi-sovereign positioning and new benchmarks for investors

By entering bond markets, EPS would effectively position itself as a quasi-sovereign issuer, creating an additional pricing benchmark alongside Serbian government debt. For international investors, this could provide exposure to a large, system-critical utility undergoing transition, with an implicit link to sovereign risk but also potential yield differentiation. For Serbia’s financial system, the prospect is that domestic liquidity could be recycled into tradable instruments while attracting external capital inflows.

From centrally managed utility to more market-oriented operator

EPS also appears to be repositioning its role within the energy sector. The company is moving from a centrally managed operator toward a more market-oriented entity that would be increasingly open to partnerships, co-investments and project-level financing structures. This includes potential collaboration with private developers on renewable assets and acquiring ready-to-build projects to accelerate capacity expansion.

Regulatory alignment links operational flexibility with financing needs

The push toward market-based operations is being driven not only by financial constraints but also by regulatory and integration pressures. Alignment with EU electricity market rules—covering balancing mechanisms and cross-border trading—requires greater operational flexibility. The introduction of negative pricing reinforces this direction by incentivising generation optimisation and investment in flexibility assets such as battery storage and demand response.

Execution risk depends on rating outcome

Whether EPS can secure favourable terms will hinge on how rating agencies assess its profile. Achieving an investment-grade or near-investment-grade outcome would support tighter pricing and broader investor participation, including ESG-focused funds targeting green infrastructure. A weaker rating could raise borrowing costs and limit access to long-tenor financing, complicating execution of the investment programme.

Legacy coal assets remain part of the assessment

Rating considerations are expected to focus on balance sheet transparency, governance standards and how EPS manages legacy coal assets. While thermal generation remains important for system stability—especially when renewable output is low—it introduces exposure to carbon costs and regulatory tightening. EPS therefore faces the challenge of balancing gradual coal phase-down with rapid deployment of renewables alongside flexibility solutions.

Regional context: peers already tap international bond markets

The company’s move also reflects regional catch-up pressures. Utilities such as ČEZ Group and MVM Group have established credit ratings and regular access to international bond markets, enabling them to finance large-scale investments at competitive costs. EPS’s entry would represent a significant step toward bringing Serbia’s energy sector closer to European financing standards.

Policy pressure from decarbonisation frameworks adds urgency

The broader policy environment is tightening as well. Mechanisms such as the Carbon Border Adjustment Mechanism are beginning to reshape regional electricity and industrial competitiveness by increasing pressure on carbon-intensive generation. In this context, green bonds are presented as a route for EPS to finance decarbonisation while maintaining reliability.

Taken together—market liberalisation, shifting price formation including negative prices, regulatory alignment demands and high capital intensity—EPS faces a narrow execution window. The company must simultaneously build a credible renewable pipeline, secure suitable financing terms tied to its credit rating outcome, and manage operational risks in a more exposed market environment. If successful, EPS would not only reshape its own funding trajectory but also set a precedent for how state-owned utilities in South-East Europe navigate decarbonisation while maintaining financial discipline.
