Research Methodology for the Renewable Energy Market

1. Market Definition and Scope

The Renewable Energy Market would be defined based on the technologies and activities included in the study. The scope could cover solar PV, concentrated solar power, onshore wind, offshore wind, hydropower, bioenergy, geothermal, and marine energy. Depending on the report objective, renewable energy storage, renewable hydrogen, renewable fuels, equipment manufacturing, EPC services, and operation and maintenance services could be treated separately rather than included directly in the market value.

The market would be measured in US$ million/billion, while installed capacity would be tracked in MW/GW and electricity generation in GWh/TWh. IRENA provides country-level renewable capacity and generation datasets by technology, while the IEA provides historical and forecast data covering renewable electricity, heat, and renewable fuels.

2. Estimate Installed Renewable Energy Capacity

The first step would be to identify the total installed renewable capacity by technology and geography.

The calculation would be:

Total Renewable Capacity = Solar + Wind + Hydropower + Bioenergy + Geothermal + Other Renewables

Capacity would be collected separately for utility-scale and distributed generation wherever data were available. IRENA's capacity statistics measure maximum net generating capacity and provide technology-level country data, making them suitable for establishing the installed-capacity base.

3. Estimate New Annual Capacity Additions

Annual additions would then be calculated for each renewable technology:

New Capacity Added = Current-Year Installed Capacity - Previous-Year Installed Capacity + Retirements/Adjustments

This would capture new solar farms, wind farms, hydroelectric projects, biomass plants, geothermal facilities, and other renewable installations.

Project-level announcements, government procurement programs, auctions, PPAs, and developer pipelines would be used to identify capacity additions that may not yet appear in installed-capacity statistics.

4. Estimate Electricity Generation

Installed capacity alone would not represent the market value, because different renewable technologies operate at different capacity factors.

Annual generation would therefore be estimated as:

Renewable Generation (MWh) = Installed Capacity (MW) X Capacity Factor X 8,760 hours

The calculation would be performed separately for solar, wind, hydro, bioenergy, geothermal, and other technologies.

IRENA tracks both capacity and electricity generation by technology and country. Its methodology also highlights capacity factor as an important measure of asset utilisation.

5. Estimate Average Electricity Value

The value generated by renewable electricity would then be estimated using applicable electricity prices, PPAs, auction prices, tariffs, or merchant-market prices.

Renewable Energy Revenue = Renewable Electricity Generation X Average Realized Electricity Price

Where project-specific PPA prices were available, they would be used. Otherwise, weighted electricity prices by country, technology, and customer type would be applied.

This distinction would be important because the wholesale electricity price, PPA price, auction tariff, and retail electricity price represent different stages of the electricity value chain. The IEA tracks electricity-price developments and market structures, including long-term contracts and other electricity-market mechanisms.

6. Calculate the Bottom-Up Market Size

The core market estimate would be developed separately for each renewable technology:

Market Size = Renewable Capacity/Generation X Applicable Market Value per Unit

For a generation-based approach:

Market Size = Σ [Renewable Generation by Technology X Average Realized Price]

For an investment/equipment-oriented market definition:

Market Size = Σ [New Capacity Added X Average Installation Cost per MW]

The appropriate formula would depend on whether the report defined the Renewable Energy Market as electricity generation revenue or as the investment/value of renewable energy deployment.

7. Estimate Technology-Level Markets

The market would be divided into major renewable technologies:

• Solar PV
• Concentrated Solar Power
• Onshore Wind
• Offshore Wind
• Hydropower
• Bioenergy
• Geothermal
• Marine Energy, etc.

For each segment, capacity additions, generation, project costs, utilization, electricity prices, and revenue would be estimated independently.

IRENA's renewable cost database covers major renewable technologies and provides project-level information on CAPEX, OPEX, capacity factors, and LCOE, which could be used to support technology-level assumptions.

8. Estimate Investment and Project Pipeline

The project pipeline would provide another important market indicator.

For each announced, under-construction, and commissioned project, the analysis would capture:

• Project developer
• Technology
• Location
• Planned capacity
• Project status
• Expected commissioning year
• Estimated investment
• EPC contractor
• PPA/auction arrangement
• Expected generation

Projects would then be classified as announced, permitted, under construction, operational, or cancelled to avoid double counting.

9. Estimate CAPEX per MW

For renewable-energy deployment measured through investment, technology-specific CAPEX would be applied:

Renewable Investment = New Capacity (MW) X CAPEX per MW

CAPEX would vary significantly between solar PV, onshore wind, offshore wind, hydropower, geothermal, and bioenergy.

IRENA's cost database would be used as a benchmark because it contains project-level cost and performance information across major renewable technologies.

10. Company-Level Revenue Validation

The market estimate would then be cross-checked against major companies operating across renewable generation, development, EPC, equipment, and services.

The analysis would examine:

• Renewable-energy revenue
• Installed renewable capacity
• Annual capacity additions
• Project pipeline
• Geographic exposure
• Technology mix
• EPC and O&M revenue

Company disclosures would be used to determine the portion of revenue attributable specifically to renewable energy rather than applying the entire corporate revenue to the market.

11. Validate Through Electricity Generation Data

The bottom-up market would be compared with official electricity-generation statistics.

The calculation would use:

Renewable Share = Renewable Electricity Generation ÷ Total Electricity Generation

The resulting renewable generation estimate would be compared with IRENA, IEA, national electricity regulators, utilities, grid operators, and energy ministries.

The IEA's Renewables Information database provides historical renewable supply and consumption data and includes installed capacity and renewable input into electricity and heat production for covered countries.

12. Use a Top-Down Approach

A top-down estimate would be developed using the overall electricity market or energy market as the starting point.

For example:

Renewable Energy Market = Total Electricity Market X Renewable Energy Share

Alternatively:

Renewable Investment = Total Power-Sector Investment X Renewable Investment Share

The renewable share would be established separately for each country and technology rather than applying a single global percentage.

13. Validate Through LCOE and Project Economics

Levelized Cost of Electricity would be used as an economic validation parameter rather than as the market size itself.

LCOE = Lifetime Project Costs ÷ Lifetime Electricity Generation

IRENA uses LCOE as a key metric for comparing renewable technologies, alongside CAPEX, OPEX, and capacity factors. However, LCOE does not include transmission and distribution costs beyond the plant boundary and therefore should not be directly treated as market revenue.

14. Estimate Distributed Renewable Energy

Distributed generation would be estimated separately from utility-scale projects.

The analysis would cover:

• Residential rooftop solar
• Commercial rooftop solar
• Industrial solar
• Small wind
• Off-grid systems
• Distributed bioenergy
• Other decentralized renewable systems

The estimation would use installations, average system size, equipment prices, installation costs, and replacement cycles.

This would be particularly important because distributed solar represents a substantial component of renewable-capacity expansion.

15. Validate Through Trade and Equipment Data

Import and export statistics would be used to cross-check equipment demand, particularly for:

• Solar modules
• Inverters
• Wind turbines/components
• Batteries
• Generators
• Renewable-energy electrical equipment

The analysis would use relevant HS codes, customs data, UN Comtrade, ITC, and national trade databases.

This would provide a supply-side check on the equipment required to support estimated renewable-energy deployment.

16. Estimate Regional/Country Markets

For a global or regional study, the market would first be estimated at the country level.

Country Renewable Market = Capacity/Generation X Country-Specific Value

Country estimates would then be aggregated:

Regional Market = Σ Country Renewable Energy Markets

This approach would avoid distortions caused by applying a single electricity price, CAPEX assumption, or capacity factor across multiple countries.

17. Estimate Historical Market Size

Historical market values would be reconstructed using:

• Installed renewable capacity
• Annual capacity additions
• Renewable electricity generation
• Historical electricity prices
• Project CAPEX
• Technology-specific capacity factors
• Renewable investment
• Company disclosures
• Government and utility data

Historical estimates would be reconciled against IRENA and IEA datasets to maintain consistency across years. IRENA's renewable statistics provide long-term country and technology data, while the IEA provides historical renewable supply and consumption information.

18. Forecast the Renewable Energy Market

The forecast would be developed technology by technology rather than applying one CAGR to the entire market.

Forecast assumptions would include:

• Renewable capacity targets
• Electricity-demand growth
• Government auctions
• PPAs
• Renewable portfolio requirements
• Declining technology costs
• Grid expansion
• Energy-storage deployment
• Corporate renewable procurement
• Financing conditions
• Fossil-fuel prices
• Permitting and regulatory developments
• Project pipeline

For each technology:

Future Capacity = Base-Year Capacity + New Capacity Additions - Retirements

Then:

Future Generation = Future Capacity X Capacity Factor X 8,760

And:

Future Market Value = Future Generation X Expected Realized Electricity Price

IEA's renewable forecasting framework considers technology potential, costs, deployment constraints, policy incentives, and other system factors when projecting renewable deployment and investment needs.

19. Third Validation and Market Triangulation

The final market size would be established through three independent approaches:

Demand-side: electricity generation X realized renewable electricity value

Supply-side: installed/new capacity X project or equipment value

Top-down: total electricity/energy market X renewable share

The three estimates would be compared and reconciled. Large differences would be investigated by reviewing capacity factors, project commissioning dates, electricity prices, captive generation, distributed generation, PPAs, and whether equipment or electricity-generation revenues had been included.

Core Formulas

For an electricity-generation market:

Renewable Energy Market = Σ [Renewable Electricity Generation X Average Realized Electricity Price]

Renewable Electricity Generation = Installed Capacity X Capacity Factor X 8,760

For a renewable deployment/investment market:

Renewable Energy Market = Σ [New Renewable Capacity X Average CAPEX per MW]

The methodology would therefore allow the market to be measured consistently in US$ million/billion, while maintaining supporting metrics in MW/GW, GWh/TWh, project investment, and renewable-energy share.
