PPIAF provides three types of technical assistance for governments of low- and middle-income countries. First, PPIAF assists governments to develop enabling environments that facilitate private investment in infrastructure by: preparing and reviewing policy frameworks; developing and implementing legal and regulatory frameworks; designing and strengthening new institutions to support private participation in infrastructure; and translating the enabling laws, regulations and policies into specific infrastructure transactions.

Second, PPIAF’s project cycle-related assistance addresses a lack of capacity to develop and transact “bankable” projects that can attract private sector investment. Examples of project cycle support provided by PPIAF includes the preparation of  financial models, contracts and bidding documents, and providing advisory support after transactions reach financial closure.

Third, capacity and awareness building [6] activities help developing countries by sharing knowledge of key issues related to private infrastructure development. PPIAF identifies and disseminates knowledge by publishing best practices studied, developing toolkits, and conducting workshops and seminars.

PPIAF also supports sub-sovereign authorities and utilities through its Sub-National Technical Assistance (SNTA) [7]program. The SNTA program helps sub-national entities, such as municipalities and utilities, improve their creditworthiness and develop their capacity to access market-based financing without sovereign guarantees. Technical assistance provided by the SNTA program includes helping clients prepare for and obtain credit ratings, structure and negotiate financial transactions, and carry out specific creditworthiness improvement activities.
