Companhia Energética de Minas Gerais (CIG) - Porter's Five Forces: Competitive rivalry

The competitive rivalry within the Brazilian energy sector for Companhia Energética de Minas Gerais is sharp, particularly as the market evolves toward greater liberalization. You see this pressure from established national players who operate at a different scale.

Integrated national generation and transmission (G&T) players challenge Companhia Energética de Minas Gerais on sheer scale and the speed of their renewable energy pipelines. Competitors like Eletrobras dominate in hydro and transmission assets, while Engie Brasil, Auren, AES Brasil, and Neoenergia are actively scaling up their low-carbon fleets. This dynamic forces Companhia Energética de Minas Gerais to focus on its core strength: its dominant retail and distribution presence within Minas Gerais.

The free-market segment (ACL) has seen rivalry intensify through 2024 and into 2025 as more captive customers migrate. Energy traders and retailers, including Comerc, Delta Energia, Brookfield/Origin, Engie, and Raízen Power, are aggressively competing for large commercial and industrial clients by offering structured Power Purchase Agreements (PPAs) and green energy attributes.

Companhia Energética de Minas Gerais is responding to this competitive environment with significant capital deployment. The company launched its most ambitious investment program to date, committing BRL 6.3 billion in 2025 toward modernizing its infrastructure to compete on service quality. For context on competitive spending, look at the planned capital expenditure of key rivals:

Company	Investment Focus/Period	Reported/Planned Amount (BRL)
Companhia Energética de Minas Gerais (CIG)	Total Investment Program 2025	6.3 billion
Engie Brasil Energia	Estimated Capex for 2025	6.32 billion
Engie Brasil Energia	Planned Investment for 2026	2.75 billion

The state-controlled ownership structure of Companhia Energética de Minas Gerais introduces a distinct layer of political risk that inherently limits the company's ability to make the most aggressive market maneuvers seen from fully private competitors. As of June 2025, the State of Minas Gerais maintains a controlling stake, holding 51.0% of the voting capital. This governance structure means the rating incorporates political cycle risks, even if the state has refrained from direct operational interference in recent years. The proposed privatization remains uncertain, dependent on legislative approval and potentially a popular referendum.

Competition for new regulated assets through government auctions is fierce, representing a major avenue for growth and a key battleground. The Energy Research Company (EPE) projected that planned 2025 electricity auctions could attract between R$47 billion and R$57 billion in total investments, split between generation and transmission infrastructure. Major players are mobilizing for these tenders.

Specifically in transmission, the unique auction scheduled for October 31, 2025, offered 11 lots with an estimated investment of BRL 7.6 billion, or alternatively, seven lots with an estimated investment of R$ 5 billion. Companies keeping a close watch on this and future tenders include Eletrobras, Eneva, Petrobras, Âmbar, CPFL, CTG, Spic, Auren, and Copel. Companhia Energética de Minas Gerais - CEMIG GT, for instance, had a gross Regulated Annual Revenue (RAP) of about R$ 1.36 billion in the 2024-2025 cycle, which it seeks to grow through these competitive bids.

The competitive intensity is further illustrated by the sheer volume of investment planned by the sector:

• Total estimated investment in 2025 generation and transmission auctions: R$47 billion to R$57 billion.
• Investment in the October 31, 2025, transmission auction: BRL 7.6 billion (11 lots).
• Companhia Energética de Minas Gerais H1 2025 distribution investment: R$ 2.2 billion.
• Companhia Energética de Minas Gerais total planned 2025 investment: BRL 6.3 billion.
• Companhia Energética de Minas Gerais adjusted EBITDA (12 months ended June 2025): BRL 9.6 billion.

Companhia Energética de Minas Gerais (CIG) - Porter's Five Forces: Threat of substitutes

The threat of substitutes for Companhia Energética de Minas Gerais (CIG) is substantial, driven primarily by the direct competition from decentralized generation (DG), which is overwhelmingly solar photovoltaic (PV) in the Brazilian context. As of late 2025, Brazil's total distributed generation capacity is approximately 43 GW, a significant portion of which is located in the Southeast region, where Minas Gerais holds 4.63 GW of that capacity. The market saw a projected total addition of only 8.5 GW in 2025, a slowdown from the previous year, but solar PV still accounts for 99% of all DG installations. This distributed capacity directly substitutes for grid power supplied by Companhia Energética de Minas Gerais (CIG) customers, particularly in the residential and commercial segments. For perspective, Brazil's utility-scale solar capacity stood at only 17.9 GW by mid-2025, dwarfed by the distributed segment's 40 GW by June 2025.

Companhia Energética de Minas Gerais (CIG) is actively countering this trend by re-entering the centralized solar generation space to compete more effectively on price and supply security. The company launched its first major solar plant in July 2025, a clear strategic move to address the substitute threat head-on. This action signals a commitment to integrating utility-scale renewable capacity that can better match the profile of distributed generation.

Project Name	Location	Installed Capacity (MW)	Investment (R$)	Inauguration/Status
UFV Advogado Eduardo Soares	Montes Claros, MG	85	460 million	July 2025
São Gonçalo do Abaeté Project (Total)	São Gonçalo do Abaeté, MG	70 (Seven 10 MW units)	390 million	Upcoming (in the coming months)

Energy efficiency technologies act as an indirect substitute by reducing the overall volume of energy demanded from the grid, thereby limiting Companhia Energética de Minas Gerais (CIG)'s revenue base. While specific Brazilian energy efficiency consumption data for 2025 is complex to isolate from broader economic factors, the market's overall deceleration in DG growth-from a projected 25% growth in 2025 to a potential addition of only 8.5 GW for the full year-suggests that factors beyond just new solar installations are tempering demand or investment appetite.

The viability of DG as a substitute is significantly boosted by regulatory developments concerning Battery Energy Storage Systems (BESS). The legal framework is solidifying, with initial energy storage regulations from Agência Nacional de Energia Elétrica (ANEEL) expected in the second half of 2025, addressing grid access and remuneration, including revenue stacking. Furthermore, the approval of Conversion Bill No. 1.304, originating from Provisional Measure 1.304/25, solidifies storage's role as a transversal activity. However, the cost side remains a hurdle; the tax burden on BESS in Brazil is calculated to reach up to 70% of the total system value, which Companhia Energética de Minas Gerais (CIG) and its customers must factor into the total cost of ownership for storage solutions.

Companhia Energética de Minas Gerais (CIG) - Porter's Five Forces: Threat of new entrants

The threat of new entrants for Companhia Energética de Minas Gerais (CIG) is bifurcated, heavily constrained in the infrastructure segments but increasingly relevant in the commercialization space due to regulatory shifts. The sheer scale of existing physical assets creates a formidable initial hurdle for any competitor looking to replicate CIG's integrated model.

The capital expenditure required to compete in the core infrastructure business is a major deterrent. Companhia Energética de Minas Gerais has planned total investments exceeding R$39 billion between 2025 and 2029, primarily focused on maintaining and expanding its network within Minas Gerais state. This massive outlay signals the financial muscle needed just to keep pace. To put that into perspective regarding existing assets, as of December 31, 2024, CIG operated 357,044 miles of distribution lines and 4,754 miles of transmission lines. Furthermore, in the transmission segment, the gross RAP (Regulated Asset Base) for the 2024-2025 cycle was R$1.36 billion.

The Distribution and Transmission segments remain heavily protected, effectively operating as regulated monopolies where entry barriers are exceptionally high. Companhia Energética de Minas Gerais, through its subsidiaries, is responsible for distributing electricity to approximately 9.3 million clients in Minas Gerais. The existing, extensive, and regulated network infrastructure represents a massive sunk cost barrier. Moreover, bottlenecks in transmission grid expansion and the recurrence of access denials for new projects suggest that connecting new generation capacity to the existing system is not straightforward, reinforcing the incumbent advantage.

However, regulatory changes are actively lowering barriers in the less capital-intensive parts of the value chain, specifically the Free Market. Provisional Measure No. 1,300/2025 is driving this liberalization. The schedule confirms that industrial and commercial consumers served at low voltage will gain the right to freely choose their suppliers starting August 1, 2026, with full market opening, including residential consumers, confirmed for December 2027. This opens the door for new commercializers and generators to target CIG's captive customer base.

Consequently, new entrants are strategically focusing on generation and trading, deliberately avoiding the massive capital requirements of grid ownership. This shift is supported by the fact that existing beneficiaries of tariff discounts on TUSD/TUST for incentivized energy must secure contracts by December 31, 2025, to retain the benefit, pushing new players toward direct market negotiation. Still, even in generation, regulatory changes are tightening the screws on smaller players; for instance, new rules under MP 1,300/2025 for self-production by equivalence now require a minimum aggregate contracted demand of 30,000 kW, with individual units needing at least 3,000 kW.

Here's a quick look at the structural differences in entry barriers:

Segment	Primary Barrier Type	Key Data Point
Distribution/Transmission	Massive Capital Expenditure & Regulatory Control	CIG planned investments through 2029: R$39 billion
Generation (New Projects)	Grid Access & Self-Production Rules	New self-production minimum aggregate demand: 30,000 kW
Energy Trading/Commercialization	Market Opening Timeline	Full Free Market opening date: December 2027
