Renewable Energy

Many countries have adapted energy policies and laws to encourage investment in renewable energy (RE) sources. They are also looking to different financing, legal and commercial frameworks, including public-private partnerships (PPPs) to leverage private capital and expertise to support the development of renewable energy projects.

This section includes links to RE policies, laws, and regulations from countries around the world, key sample and standardized contracts used for the implementation of RE projects, as well as, reading materials and links to useful online resources.

Renewable Energy Policies, Laws and Regulations

The recent growth of the RE market has been driven to a large extent by policies, laws and regulations that encourage private investment in RE. Often these approaches are combined in order to optimize the benefits of several mechanisms.

Key regulatory and pricing mechanisms to promote the uptake of RE include:

  • National RE targets - Legal requirement to produce a certain portion of energy from RE sources together with a timeline by which the target has to be reached.

  • Feed-in tariffs (FiT)/feed-in premiums (FiP) - FiT and FiP guarantee the purchase of generated RE at a fixed price or premium for a defined period in time.

  • Quota Obligations or Renewable Portfolio Standards (RPS) - Requirements for utilities to source specific percentages from RE sources.

  • Grid Access Provisions - Provisions that give RE producers facilitated access to the grid, e.g. through mandated grid access or reduced transmission fees.

  • Auction Schemes - Public competitive bidding for procuring new RE capacity at the lowest possible price.

In line with its more market-oriented approach to power sector regulation generally (see Energy  Laws and Regulations), Australia operates a market-based renewable energy target scheme under the Renewable Energy (Electricity) Act 2000 (Cth). The scheme aims to incentivize electricity generation from renewable sources.

Under the scheme, large renewable power stations and the owners of small-scale systems can generate renewable energy certificates for every megawatt of electricity they produce. The certificates can then be sold to electricity buyers on the wholesale market, who are required to surrender a certain number of these renewable energy certificates every year (expressed as a percentage of the volume of electricity they purchase in that year) to meet their surrender obligations under the scheme. The sale of renewable energy certificates provides an additional source of revenue for renewable energy projects, which acts as an incentive for investment into this sector. The scheme is regulated by the Australian Clean Energy Regulator.

The Australian Financial Market Association publishes template documents for the trading of renewable energy certificates under the scheme.


Brazil introduced an auction system to procure electricity in 2004 (Law no. 10.848/2004, and Decree no 5163/2004) for the market regulated by ANEEL, the Brazilian Electricity Regulatory Agency.

In the same year EPE – Empresa de Pesquisa Energética was created (Law no. 10.847). The EPE Web Page on Energy Auctions provides information and updates on the Brazilian energy auctions organized by ANEEL as well as links to Laws and Regulations in the Brazilian Energy Sector.

Alternative Energy Auction of July 2011 – Regulation Portaria MME 113 of Feb 1, 2011 - Authorizes ANEEL to organize alternative energy auctions and provides pre-qualification criteria for developers/investors interested in participating in the auction. The capacity to be awarded and the types of energy sources to be promoted at the auctions are defined by MME - Ministerio de Minas e Energia. All types of auctions are conducted by CCEE – Camara de Comercialização de Energía Elétrica, a regulated non- profit entity formed by agents from the power market, on behalf of ANEEL.

Further to the auction-based scheme, a new FIT-scheme has been introduced by the Brazilian government in December 2015 to promote distributed power generation from renewable sources by consumers (Executive Order 538/2015).

A draft Bill is currently under discussion in the Brazilian Congress, following two public hearings in July 2017 aimed at reformulating and improving the Brazilian power sector’s legal framework. One of the topics discussed in the hearing was specific measures that could positively affect the market. Specifically, the hearings discussed the possibility for the establishment of public auctions specifically for capacity sale (unlike existing auctions, which sell energy produced by power plants).

Chile’s RE incentive scheme is based on several different laws, including Law 20257 (Ley de Energías Renovables No Convencionales) as amended by Law 20701 (Procedimiento para Otogar Concesiones Eléctricas) and Law 20018 (Modifica el Marco Normativo del Sector Electrico), as amended by Law 20805 (Perfecciona el Sistema de Licitaciones de Suministro Eléctrico para Clientes Sujetos a Regulaciones de Precios). For more details see Renewable Energy in Latin America: Chile, Norton Rose Fulbright, 2017.


The Renewable Energy Sources Act, also referred to as Renewable Energy Law (Erneuerbare Energien Gesetz – EEG) of 2000 as amended through July 2017 sets out the main support scheme for electricity generation from wind, hydro, solar, biomass and sewage gas combustion, as well as geothermal energy. It used to be based on a FiT scheme and has recently introduced an auction model for utility-scale projects.


Lao PDR has implemented a number of policies to reduce greenhouse gas emissions and increase the use of renewable resources in its energy make up. The key policies include:

  • National Strategy on Climate Change – the strategy includes among its priorities: accelerating the development of renewable energy sources such as wind, solar and hydropower, and development of cleaner technology for the use of the Laos’ coal resources; and

  • Renewable Energy Development Strategy, which among other things:

    1. sets a target to increase the share of the renewable energy to 30% of the aggregate energy consumption by 2025;

    2. sets a target to increase the share of biofuel to 10% of aggregate transportation energy consumption;

    3. outlines a range of financial incentive schemes to encourage investment in the renewable sector; and

    4. provides for the set-up of a Renewable Energy Fund to finance various development and research activities in the renewable sector.

See Sample Energy Laws and Regulations for an overview of Laos’ regulatory framework.


The Electric Power Industry Reform Act of 2001 (“EPIRA”) mandates, among other things, that the Department of Energy (“DOE”) shall encourage private sector investment in renewable energy sources (see Sample Energy Laws and Regulations for a more detailed summary of the EPIRA).

Consequently, the government of the Philippines has enacted a number of laws and policies including:

  • the Renewable Energy Act of 2008. Among other things, the Act establishes:

    1. the National Renewable Energy Board (“NREB”) to set minimum targets of generation from renewable energy sources;

    2. a Feed-in Tariff (“FiT”) system designed to incentivize the development of generation projects from renewable sources;

    3. a Renewable Energy Market (“REM”) for the trading of renewable energy certificates to facilitate meeting the minimum renewable generation targets set by the NREB; and

    4. the Green Energy Option program, which provides end-users with the option to choose renewable energy resources as their sources of energy; and

  • the National Renewable Energy Program, which seeks to increase the renewable-energy based power capacity of the country by:

    1. implementing a comprehensive approach to address the challenges and gaps that prevent or delay the application of renewable energy technologies; and

    2. outlining action plans necessary to facilitate and encourage greater private sector investments in renewable energy development.

Feed-in Tariffs

The Philippine Feed-in Tariff (“FiT”) scheme is an example of how a largely market-oriented approach to incentivizing the development of renewable energy sources can be adopted in less mature electricity markets. The Renewable Energy Act of 2008 established a scheme, which provides emerging independent power producers (“IPPs”) with a guaranteed Php per kWh price for electricity generated through renewable energy sources for a period of 20 years. This provides a degree of cushioning for renewable projects against pricing volatilities in the Philippine electricity market (thereby facilitating their finance and development). The government’s role is broadly analogous to that of a private hedge provider for the project’s revenue stream, while the economic and commercial structures of the project are largely left to the private sponsors.

The FiT rates are set by the Energy Regulatory Commission (“ERC”) with recommendations from the National Renewable Energy Board (“NREB”). The FiT rates are also subject to a degression mechanism, to account for the reduced cost of deploying renewable generation technology over time. The degression rate depends on the year in which the relevant renewable energy plant started commercial operation and the type of renewable energy involved.

The FiT system is largely funded through the Fit-Allowance (“FiT-All”), a levy paid by all consumers who are supplied with electricity through the distribution or transmission network. The levy is set annually by the ERC, collected by utility and electricity suppliers, then distributed to renewable energy generators by the National Transmission Corporation (“TransCo”), a government owned and controlled agency. The Guidelines on the collection of the FiT-All and disbursement of the FiT-All Fund were adopted by the ERC in 2013.


Article 2 of European Directive 2009/28/EC defines “electric energy from renewable sources” as electric energy coming from renewable non-fossil sources, namely wind, solar, aerothermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogasses. This definition is further developed in Spain through article 2 of Royal Decree 413/2014.


As per Royal Decree 1955/2000 the building, operation, modification, temporary or definitive closure and transfer of renewable-electricity generating assets are subject to prior administrative authorizations. They must be granted by the relevant Spanish autonomous community or by the Ministry for Ecological Transition and Demographic Challenge when such actions affect more than one Spanish Autonomous Community or have an installed capacity which exceeds 50 MW, and can be summarized as follows:

  • administrative authorization, if appropriate, in conjunction with the environmental impact study;

  • approval of the execution project; and

  • start-up certificate – the relevant authorities issue the start-up once the project is completed and after having completed the necessary technical inspections and verifications of the project.

Remuneration Regime

The Spanish incentive scheme for renewable generation provides an example of a partially market-oriented policy solution to incentivizing renewable energy developments. In general terms, under the Spanish scheme (mainly regulated in Law 24/2013, Royal Decree 2019/1997 and Royal Decree 413/2014) renewable power generators sell the electricity they generate:

  1. into the Spanish wholesale market (“OMIE”) and receive market price for such sales; or

  2. to specific customers by means of bilateral agreements (Power Purchase Agreements or “PPAs”) which can be either:

    1. physical (long-term PPA) with a specific amount of power sold at a fixed price per MWh; or

    2. synthetic (financial PPAs) which, in general are structured as a hedging agreement through a contract for differences, with no physical delivery of electricity, consisting of the financial coverage of the price of energy, adjusting the differences between the wholesale market price and the agreed price.

In addition, they may also receive additional state regulated payments during their respective regulatory lives, as an incentive to encourage the use of renewable generation sources.

As set out in Royal Decree 413/2014, the specific remuneration additional to market revenues consists of:

  1. a capacity supplement in €/MW to cover investments not recovered in the market; and

  2. if applicable, an operation supplement in €/MWh when operating costs cannot be recovered in the market. This specific remuneration is calculated taking into account standard installations throughout the regulatory life of the power plant, and assuming an efficient and well-managed company.

The granting of this specific remuneration scheme will be determined on a competitive basis through state auctions. The result of the auctions will determine the value of the supplement in €/MW.

Established in 1995 and funded by the U.S. Department of Energy, DSIRE is managed by the North Carolina Clean Energy Technology Center.


The Vietnamese Government has implemented a number of incentives to promote the development of renewable energy, which are primarily in the form of tax relief or government grants. The key policies include:

  • Decision No. 2068/QD-TTg dated 25 November 2015 provides the following incentives:

    • zero import duty for assets to form the fixed assets of a renewable energy project, and for materials and semi products which are unavailable in the domestic markets;

    • corporate income tax exemption or reduction;

    • land rental exemption or reduction; and

    • government funding for research and technology of pilot projects.

  • Decision No. 11/2017/QD-TTg dated 4 November 2017, as amended by Decision No. 02/2019/QD-TTg dated 8 January 2019, also provides incentives for solar energy projects, which are entitled to an import duty exemption for:

    • goods imported to form the fixed assets of the projects; and

    • materials, semi-products and fuel that are not available locally.

  • Circular No. 02/2019/TT-BCT introduces notable changes to the regulations on wind power projects and the mandatory terms of wind power purchase agreements.

Renewable Energy Sample Project Documents and Contracts

Renewable energy projects rely on a number of legal contracts. One central contract is the power purchase agreement (PPA), which governs the sale and purchase of power:

See also Key Features of Power Purchase Agreements.

Other important contracts include land use agreements, supply agreements, installation agreements, O&M agreements and implementation agreements.

Below are links to sample project documents that were developed for multiple renewable energy sources. For sample documents that relate to specific resources see the sample project documents under Solar Power, Wind Power, Hydropower, Biomass and Geothermal.

Reference: Sample PPAs - The Energy Regulatory Commission (“ERC”)  has published standard documentation for the offtake of electricity from Renewable Energy (“RE”) Plants eligible for the Philippine Feed-in Tariff (“FiT”) system. The principal agreement is the Renewable Energy Payment Agreement (“REPA”) under which TransCo (the FiT Allowance Administrator) pays the owner of the eligible RE Plant (RE Developer) the FiT rate for the plant’s metered energy output. The economic function of the REPA is broadly analogous to a synthetic PPA with private hedge counterparties, which are used in more established electricity markets, to provide revenue stability for the project (see Synthetic PPAs). Separately, where a RE Plant does not operate in the Philippine Wholesale Electricity Spot Market (“WESM”), the RE Developer and local host distribution utility (“DU”) must enter into a Renewable Energy Supply Agreement (“RESA”) for the offtake of electricity generated by the plant.

The 20-year agreement is applicable for solar, hydro, biomass, geothermal and wind plants and outlines the provisions commonly found in PPAs for private power projects internationally. The PPA is based on the assumption that the developer will finance the project through project finance arrangements. The Seller will also enter into an implementation agreement with the government of Zambia and will obtain a Generation License from the energy regulator in Zambia. The standardized agreement is based on a REFIT policy to stimulate renewable energy production and to promote private sector participation in energy sector.
