Objectives of the Transaction

The objective of the Transaction is to increase the company’s competitiveness, value creation and capacity to grow. With the Transaction Renova will recycle invested capital at an attractive and predictable cost for both the backlog and for the Pipeline, and will gain new options for financing based on Backlog exchange contracts and Terraform shares received as payment. The need to issue equity for development of Backlog projects will be equalized.

Further, the dividends that Renova will receive from TerraForm Global, company oriented to the continuous growth of dividends, will be a source of funding for the multiple possibilities for Renova’s growth.

Mr. Mathias Becker, CEO of Renova Energia, comments:

“This operation will be an important milestone in the history of the Latin American electricity sector, and principally in the history of the Company, because it will place us once again in the leadership of the renewable energy sector, since it will enable us to recycle capital at lower and predicable costs, and will give us access to financings not available to other companies of the sector. We have great confidence in the growth of renewable sources in the world, and we are prepared to take advantage of the opportunities of this growth.

Conditions precedent for completion of the Transaction

Completion of the two phases of the Transaction described above is subject to certain conditions precedent, which include: completion of the IPO of TerraForm Global (ongoing process); and obtaining of consent from third parties and regulatory approvals, including approval by Aneel and Eletrobras.

Trading volume in Cemig’s preferred shares (CMIG4) in the first half of 2015 totaled R$ 5.96 billion. Cemig continues to be one of the most liquid companies in the Brazilian electricity sector, and one of the most traded in the Brazilian capital markets.

On the New York Stock Exchange the volume traded in ADRs for Cemig’s preferred shares (CIG) in first half 2015 was US$ 2.01 billion: we see this as reflecting recognition by the investor market of Cemig as a global investment option.

The São Paulo stock exchange (Bovespa) index – the Ibovespa – was up 6.15% in the first half of 2015, closing June at 53,080 points. This performance runs contrary to the general perception of Brazil’s economic scenario in the period.

Cemig’s shares underperformed the Brazilian stock market’s principal index. Our common stock (Cemig ON) was down 11.01% in the first half of the year, and our preferred stock (Cemig PN) was down 6.85% in the half year.

The electricity market of Cemig D

Electricity billed to captive clients and electricity transported for Free Clients and distributors with access to Cemig D’s networks totaled 10,268 GWh in 2Q15, or 7.76% less than in 2Q14.

We attribute the lower consumption to macroeconomic factors such as: (i) retraction in the level of economic activity at both state and national levels; (ii) reduction of demand for goods and services; (iii) low level of private and public investment; (iv) greater selectiveness in granting of financings; (v) high levels of debt and default; (vi) uncertainties in the Brazilian political and economic outlook; and (vii) the slow pace of recovery of the international economy.

In June 2015 Cemig billed 8,012,722 consumers, or 1.4% more consumers than in June 2014. Of this total, 426 are Free Consumers using the distribution network of Cemig D.

Comments on the various consumer categories:

Residential

Residential consumption was 16.81% of the total volume of electricity transacted by Cemig, and totaled 2,386 GWh, or 2.98% less than in 2Q14.

Industrial

Electricity used by captive industrial clients was 8.65% lower in total volume than in 2Q14, and electricity transported for Free Clients was 13.70% lower.

The main Brazilian and international macroeconomic factors that could have influenced consumption by the industrial sector are:

| ¡ | In Brazil: retraction of domestic demand, accumulation of inventories, fall in industrial capacity utilization in various sectors, loss of competitiveness, reduction of the number of employees and/or reduction of the use of labor (forced vacations, shorter work shifts), lower business and consumer confidence; and low level of investments.

30

##### Table of Contents

| ¡ | Internationally: lower exports due to lower external demand.

In manufacturing industry we saw lower consumption of electricity by most of the economic sectors – especially: Ferro alloys (down 50.5%), non-ferrous metallurgy (down 15.6%), and automotive industry (down 14.9%).

Rural:

Total consumption by the rural consumer category was 750 GWh, or 11.28% less than in 2Q14. The main factor in this retraction was better climate conditions: higher rainfall and more comfortable temperatures – consumption for irrigation was 11.5% lower, and consumption by other farming activities up 1.3%.

The electricity market of Cemig GT

Cemig GT’s market – generation and transmission – comprises sales of power as follows:

| (I) | in the Free Market (Ambiente de Contratação Livre or ACL), to Free Clients, either located in Minas Gerais or in other States; and to other agents in the electricity sector – traders, generators and independent power producers;

| (II) | to electricity distributors (in the Regulated Market); and

| (III) | sales in the CCEE (Electricity Trading Chamber).

Cemig GT invoiced a total of 10,183 GWh in 2Q15, or 1.75% more than in 2Q14, reflecting sales in the CCEE.

31

##### Table of Contents

Free Clients consumed 4,745 GWh in 2Q15, or 11.19% less than in 2Q14, reflecting:

| ¡ | termination of contracts with clients at the end of 2014 that were not renewed with Cemig GT; and

| ¡ | reduction of consumption by clients due to weak demand in the Brazilian economy, with lower domestic demand for goods and services, also affected by the speed of recovery of the international market.

Trading of electricity to other agents in the electricity sector in the Free Market totaled 1,571 GWh in 2Q15.

The total sold in the Regulated Market in the quarter was 1,440 GWh.

QUALITY INDICATORS – SAIDI AND SAIFI

Cemig is continuously taking action to improve operational management, organization of the logistics of its emergency services, and its permanent regime of preventive inspection and maintenance of substations, lines and distribution networks. It also invests in training of its staff for improved qualifications, state-of-the-art technologies and standardizations of work processes, aiming to uphold the quality of electricity supply, and, consequently, maintain the satisfaction of clients and consumers.

32

##### Table of Contents

The charts below show Cemig’s indicators for duration and frequency of outages—SAIDI (System Average Interruption Duration Index, in hours), and SAIFI (System Average Interruption Frequency Index, in number of outages), since January 2014. These results reflect the investments made by the company in preventive maintenance, such as cleaning of power line pathways, tree pruning, replacement of cross-arms, maintenance of structures, replacement of poles, transformers and cables, and other work such as network shielding, and overhaul and interconnection of circuits. Another important initiative is the change of the overall technological level, with systematic investment in automation of the electricity system, which will enable automatic remote re-establishment of supply after outages.

Consolidated operational revenue

Revenue from supply of electricity:

Total revenue from supply of electricity to final consumers was R$ 5.819 billion in 2Q15, an increase of 36.31% from 2Q14 (R$ 4.269 billion).

| ¡ | The annual tariff adjustment, with average effects on the rates for captive consumers of Cemig D, of 7.07%, applicable from April 8, 2015.

| ¡ | Application of the ‘Tariff Flag’ mechanism, since January 2015, with the following charges per 100 kWh consumed: R$ 1.50 for the Yellow Flag, and R$ 3.00 for the Red Flag; and, since March 2015, R$ 2.50 for the Yellow Flag and R$ 5.50 for the Red Flag. The Red Flag was in effect in the whole of the first six months of 2015.

Revenue from Use of Distribution Systems (the TUSD charge)

The revenue of Cemig D (Distribution) from the TUSD in 2Q15 was R$ 521mn, which was 138.79% higher than in 2Q14 (R$ 218mn). This reflects the impact of the tariff adjustments in 2015—an increase of 96.21% for Free Consumers. The 2015 increases were mainly due to passing through of the CDE (Energy Development Account) amounts to the tariffs paid by consumers. The effect of the increase in tariffs was partially offset by the effect of lower activity in the industrial sector—which consumed 13.70% less electricity, year-on-year, in the period.

Revenue from transactions in the Electricity Trading Chamber (CCEE)

Revenue from transactions in electricity on the CCEE was R$ 701mn in 2Q15, compared to R$ 940mn in 2Q14—i.e. 25.44% lower. This mainly reflected the spot price (PLD—Preço de Liquidação de Diferenças) being 47.70% lower in 2Q15, at R$ 356.81/MWh (compared to R$ 682.20/MWh in 2Q14). On the other hand, the Company had more supply available for settlement in the wholesale market in 2015, and this partially offset the effect of lower sale prices, and the negative impact of the Generation Scaling Factor (GSF).

On July 27, 2015 the courts awarded Cemig GT a provisional remedy ordering the Brazilian regulator, Aneel, not to apply to the plaintiffs, until a final hearing of the action against which there is no further appeal, the effect of the MRE system for sharing hydrological risk of the system’s hydroelectric plants, when the aggregate total of generation output from the participants in this aggregate of plants is lower than their aggregate physical offtake guarantee.

CVA and Other financial components in tariff adjustment

Due to the alteration in the concession contracts of the distributors, Cemig started to recognize balances of non-controllable costs to be passed through to Cemig D’s next tariff adjustment, which represented an operational revenue of R$ 212 million in 2Q15.

Revenue from supply of gas

In 2Q15 the Company reports revenue from supply of gas totaling R$ 425mn. This is the result of consolidation of the results of Gasmig, since October 2014.

Taxes and charges applied to revenue

The sector charges that are effectively deductions from reported revenue totaled R$ 3.052 billion in 2Q15, or 117.87% more than their total of R$ 1.401 billion in 2Q14. This principally results from the increase in the charges under the Energy Development Account (CDE), and the Tariff Flag charges.

Charges for the CDE in 2Q15 were R$ 859mn, compared to R$ 54mn in 2014. The expenses included are: concession indemnities, tariff subsidies, subsidy for balanced tariff reduction, low-income consumer subsidy, coal consumption, and the Fuels Consumption Account (CCC). In 2014 certain expenses were not considered in full in the definition of the amounts of the CDE, leading to a deficit in the year. In 2015 a new budget was made for the CDE, increasing the annual amount from R$ 194 million to R$ 2.147 billion (in accordance with Aneel Resolution 1857/2015) and this was passed through to tariffs in the Sector Charges component.

The other deductions from revenue are taxes, calculated as a percentage of amounts invoiced. Thus their variations are, substantially, proportional to the changes in revenue.

Operational costs and expenses

Operational costs and expenses, excluding Financial revenue (expenses), totaled R$ 4.348 billion in 2Q15, or 29.69% more than in 2Q14 (R$ 3.352 billion).

The following paragraphs comment on the main variations:

Electricity purchased for resale

The expense on electricity bought for resale in 2Q15 was R$ 2.312 billion – compared to R$ 1.869 billion in 2Q14, an increase of 23.70%. Main factors in the increase, by company, are:

Cemig D:

| ¡ | Cemig D’s expense on electricity acquired in auctions was 54.37% higher year-on-year, at R$ 1.040 billion, in 2Q15, compared to R$ 673 million in 2Q14 – reflecting availability contracts, due to expenditure on fuel for generation by the thermal plants.

| ¡ | Its expense on electricity from Itaipu Binacional was 102.60% higher YoY. This amount, indexed to the US dollar, was R$ 401mn in 2Q15, compared to R$ 198mn in 2Q14. The changes basically reflect the increased tariff of US$ 38.07/kW-month, since January 2015, compared to US$ 26.05/kW-month in 2014. Adding to this effect was the higher Real/dollar exchange rate in 2Q15 than in 2Q14: the average rate used in invoices from Itaipu in 2Q15 was R$ 3.08, or 39.37% higher than in 2Q14 (R$ 2.21/US$).

37

##### Table of Contents

| ¡ | Cemig D’s purchases of supply in the stock market were 59.42% lower, due to Cemig D’s lower exposure to the wholesale market (R$ 201mn in 2Q15, vs. R$ 496mn in 2Q14).

Cemig GT:

Cemig GT’s expense on electricity bought for resale in 2Q15 was R$ 625 million, or 52.04% more than in 2Q14 (R$ 411 million). This reflected a volume of energy purchased in 2Q15 that was 37.21% higher (at 4,004 GWh), than in 2Q14 (2,517 GWh), as well as the higher price of supply.

Operational provisions

Operational provisions represented an expense of R$ 230mn in 2Q15, compared to R$ 42mn in 2Q14 – an increase of 446.72%. This change mainly reflected a provision of R$ 160mn made in June 2015 for losses relating to the put options for the equity interests in Parati and SAAG.

| a) | Put options for Units in FIP Melbourne

Option contracts for sale of Units (’the Put Options’) were signed between Cemig GT and the pension plan entities that participate in the investment structure of SAAG, giving those entities the option to sell their shares in the 84th (eighty-fourth) month from June 2014. The exercise price of the Put Options will correspond to the amount invested by each pension plan company in the Investment Structure, updated pro rata temporis by the IPCA inflation index (Índice National de Preços ao Consumidor Amplo, published by the Brazilian Geography and Statistics Institute – IBGE), plus 7% per year, less such dividends and Interest on Equity as have been paid by SAAG to the pension plan entities. Based on the studies made, the amount of R$ 75mn is recorded in Cemig GT relating to the best estimate of the loss on these options.

| b) | FIP Redentor

Cemig has granted to Fundo de Participações Redentor, which is a stockholder of Parati, an option, exercisable in May 2016, to sell the totality of the shares which that fund holds in Parati. The price of the option is calculated using the sum of the value of the injections of capital by the fund into Parati, plus the running expenses of the fund, less any Interest on Equity, and dividends, distributed by Parati. The exercise price is subject to monetary updating by the CDI (Interbank CD) rate plus financial remuneration at 0.9% per year. Based on the studies made, the amount of R$ 280mn is posted in the Company, relating to the best estimate of loss on that option, exercisable in May 2016.

Maturity of the put option: May 30, 2016

Deadline for statement of intent: 240 days prior to maturity.

|  |  |  |  |  |  | 1074.68 |

Gas bought for resale

The expense on gas purchased for resale in 2Q15 was R$ 262mn. The results of Gasmig have been consolidated into those of Cemig since October 2014, after Cemig acquired the 40% interest in Gasmig held by Petrobras.

Raw materials and inputs for production of electricity

The expense on Raw material and inputs for production of electricity was R$ 3mn in 2Q15, compared to R$ 88mn in 2Q14. The difference reflects the shutdown of the Igarapé Thermal Plant in 2Q15, due to the need for maintenance and installation of new equipment.

39

##### Table of Contents

Financial revenue (expenses)

Cemig reports net financial expenses of R$ 252mn in 2Q15, compared to net financial expenses of R$ 274mn in 2Q14. The main factors are:

¡ | Higher revenue from updating of the Remuneration Base of Assets (BRR): this item was a gain of R$ 102mn in 2Q15, compared to a reversal of R$ 113mn in 2Q14. The difference reflects the higher variation in the indexer of the BRR – the IGP-M inflation index – which varied by 2.27% during 2Q15, compared to a negative variation of 0.09% in 2Q14. Also, in June 2014 there was a reversal in the monetary updating of the BRR, totaling R$ 110mn, due to the final, definitive homologation of the value of the BRR of Cemig D.

¡ | Higher interest costs on loans and financings: R$ 317mn in 2Q15 – this was 57.62% higher than in 2Q14 (R$ 201mn), mainly reflecting higher debt indexed to the CDI in 2015, and also higher variation resulting from the CDI (3.02% in 2015, compared to 2.51% in 2014).

Ebitda

Cemig’s consolidated Ebitda in 2Q15 was 21.66% lower than in 2Q14. This mainly reflects operational costs and expenses (excluding effects of depreciation and amortization) 32.26% higher, partially offset by net revenue 14.70% higher:

DIVIDENDS

Cemig’s dividend policy establishes that:

¡ | 50% of Net income is distributed as obligatory dividend to the Company’s shareholders, subject to the other provisions of the by-laws and the applicable legislation;

¡ | the balance, after any retention specified in a capital and/or investment budget prepared by Cemig’s management, which complies with the Long-term Strategic Plan and the dividend policy stated in it, and has been duly approved, is applied to constitute a profit reserve to be used for distribution of extraordinary dividends, up to the maximum limit specified by law.

At the General Meeting of Stockholders held on April 30, 2015, a proposal by the Board of Directors was approved to the effect that, of the net profit for 2014, totaling R$ 3.137 billion, R$ 797 million would be allocated for payment of dividends, corresponding to 25% of the net income, the other 25% being held in Shareholders’ equity, in the account Reserve for obligatory dividends not yet distributed, to be paid as soon as the Company’s financial situation permits, in accordance with Paragraph 5 of Article 202 of the Brazilian Corporate Law.

Default

In 2015, to achieve economic and financial equilibrium for the companies of the sector, and synchronization between tariffs and the real variable costs of electricity, Aneel implemented the system of Tariff Flags, as from January, and in March also imposed an Extraordinary Tariff Increase. These measures had an impact on electricity tariffs, involving as it did a pass-through of costs to final consumers.

In this context of an exceptional increase in electricity tariffs, the Company has seen an increase in amounts invoiced that are not paid by final consumers, and this has resulted in growth in the stock of debt to levels higher than the average of recent months.

Since January, when the Tariff Flag system came into effect, the Company’s average level of default has risen by 5%. This percentage increase in default has had a negative effect on the company’s cash flow, reducing the average effective ratio of revenue collected, from 96% last year to 95% this year.

The Company uses various tools of communication and collection to prevent increase in default. These include telephone contact, sending of e-mails, use of texting, and letters. If the client does not pay, a communication is sent raising the possibility of the client being included on the ‘blacklists’ of payment defaulters held by the Credit Protection Service (Serviço de Proteção ao Crédito) run by Serasa, and by the Store Managers’ Association (Câmara de Dirigentes Lojistas, or CDL), and giving the client five days after receipt of the correspondence to regularize the situation and avoid that inclusion. If the default continues, the Company has available to it the option of cutting off supply. Aneel Resolution 414 allows cut-off of supply after 15 days from receipt of a notice to the defaulting consumer, made through the electricity bill itself.

##### Table of Contents

Historically, the majority of clients pay their bills on dates close to the due date, to avoid being in default with Cemig, and to avoid claims for collection, and the related cut-off of supply.

Electricity losses – 2Q15

Control of electricity losses is one of Cemig D’s strategic objectives, and the Company has a structure dedicated to this: its Distribution Losses Measurement and Control Management Unit. Compliance with this objective is monitored monthly through the Total Distribution Losses Index (Índice de Perdas Totais da Distribuição, or IPTD): the result in 2014 was 11.00%, for a regulatory target of 10.48% by the end of 2017. In the decision on the regulatory target, taken during the 3rd Tariff Review Cycle, the regulator, Aneel, made significant changes in the method of calculation of technical losses, imposing extremely challenging limits for Cemig D. Total losses comprises two elements: technical losses; and non-technical losses. The indicators for measurement are the PPTD (Distribution Technical Losses Percentage), and the PPNT (Distribution Non-technical Losses Percentage). The projected result for the PPTD on March 31, 2015 was 8.85%, for a regulatory target of 7.84%; the projected result of the PPNT was 2.45%, for a regulatory target of 2.64%.

Aneel measures non-technical losses with reference to the low-voltage market. Taking this into account, the result for the PPNT in relation to the low voltage market as invoiced in 1Q15 was 5.74%, for a regulatory target of 7.63% (17% below the limit set by the regulator).
