and end users. NUGs may be privately held facilities, corporations, cooperatives such as rural solar or wind energy producers, and non-energy industrial concerns capable of feeding excess energy into the system. An independent water and power producer (IWPP) is similar to an IPP, but with a unified process to also output usable treated water.


Economic situation

For most IPPs, particularly in the renewable energy industry, a

or power purchase agreement provides a long-term price guarantee. IPPs have been successful in driving the electricity sector's transition to renewables globally, owning the majority of the currently operating renewable energy generation capacity.


Germany

Rare in Germany for decades, the IPP business model has grown more common since the EEG (for renewable energy). Success in the approach depends on finding a partner for distributing the produced energy to the customer.


Canada

Electricity regulation in Canada is governed at the provincial level, and there are differences between the provinces for how IPPs are integrated into the electric system. In 2002, the government of British Columbia stipulated that new clean renewable energy generation in the province would be developed by independent power producers (IPPs) not

, save for large hydro-electric facilities. IPPs now produce a significant proportion of the power generated in BC.


Taiwan

Taiwan's electricity market was liberalized in January 1995. Nine IPP companies are currently operating in Taiwan.


United States

NUGs were rare before the enactment of the US Public Utility Regulatory Policies Act (PURPA) of 1978. The few existing NUGs were seldom able to distribute power, as the cost of building the conveyance infrastructure was prohibitive. Public utilities generated power and owned the generating facilities, the transmission lines, and the local distribution-delivery systems. PURPA, however, established a class of non‐utility generators, called Qualifying Facilities (QFs), that were permitted to produce power for resale. PURPA was intended to reduce domestic dependence on foreign energy, to encourage energy conservation, and to reduce the ability of electric utilities to abuse the purchase of power from QFs. A QF is defined as a generating facility that produces electricity and another form of useful thermal energy through the sequential use of energy, and meets certain ownership, operating, and efficiency criteria established by the Federal Energy Regulatory Commission (FERC). Section 210 of PURPA now requires

to purchase energy from QFs at the utility's avoided cost. This allows QFs to receive a reasonable to excellent price for the energy they produce and ensures that energy generated by small producers won't be wasted.

announced an investor-friendly policy to develop IPPs based on oil, coal and gas. Following the policy, 16 IPPs were established. The next year, a hydro power policy was announced, which resulted in the development of the country's first Hydro IPP. In 2002, the new government adopted a new policy, under which another 12 IPPs began operations. For the development of Independent Power Producers (IPPs)

In 2015, Pakistan adopted a new power policy by which another 13 IPPs were established, mostly by Chinese companies. A transmission policy for development of

in the private sector was also announced. More than 40 IPPs were operating in Pakistan as of 2018.


India

India also has many IPP's like ReNew Power, Adani, Onix Renewable, KPI Green Energy, Hero, Mytrah, Ostro, Greenko, Alfanar, Mahindra Susten, Jakson Ltd.Etc.
