These two types of guarantees are more applicable in regions where the energy harnessed by the renewable technology is more volatile. A basic sample PPA between the Bonneville Power Administration and a wind power generating entity was developed as a reference for future PPAs. Solar PPAs are now being successfully utilized in the California Solar Initiative's Multifamily Affordable Solar Housing (MASH) program. This aspect of the successful CSI program was just recently opened for applications. PPAs can be managed in the European market by service providers. The legal agreements between the statewide power sectors(seller) and the trader(buyer/who buys large quantity of power) will be treated as the PPA in power sector. Data center owners Amazon, Google, and Microsoft have used PPAs to offset the emissions and power usage of cloud computing. Some manufacturers with heavy carbon emission footprints and energy usage such as Anheuser-Busch InBev have also shown interest in PPAs. In 2017, Anheuser-Busch InBev agreed to purchase using a PPA from the utility company Iberdrola in Mexico for 220 MW of new wind farm energy. Recently, a new form of PPA was proposed to commercialize electric vehicle charging stations through a bi-lateral form of power purchase agreement.
