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.

For more information, visit the section on Toolkits, see Renewable Energy Projects by Resource (Solar Power, Wind Power, Hydropower, Biomass and Geothermal) or see Water Projects Using Renewable Energy.

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.

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).

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.

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:

  • The seller's primary responsibilities under a PPA developed for an independent power producer (IPP) are to build, operate and maintain a power generation facility in accordance with the requirements of the PPA and applicable law, and to deliver the agreed amount of power.
  • In turn, the buyer is obliged to purchase the energy produced and to pay the agreed tariff.
  • Various elements of the renewable energy PPA depend on the underlying incentive scheme. Typically, one price component in RE PPAs is a fixed price per kWh for electricity delivered for a certain number of years.
  • Risk allocation between the parties may be influenced by the limited ability of the seller to control the output of some RE resources. The lack of output predictability may call for some flexibility with regard to the minimum capacity to be delivered or require the offtaker to pay to some extent for delivered excess electricity.

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: Zambia Renewable Energy Feed-in Tariff (REFIT) Program: REFIT Power Purchase Agreement - Model PPA between state-owned utility and the Seller (draft of February 2016) developed by the United States Agency for International Development (USAID) with the Ministry of Energy and the regulator. 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.
