Maximizing Finance for Development in Transport

Castalia worked with the IFC to help governments structure PPPs to attract private investment for transport infrastructure projects, by developing tools that would show them how to de-risk projects. Congestion and poorly maintained highways impact welfare and reduce opportunities for trade and economic growth. If governments don’t have the money to maintain and develop transport systems, countries will be affected by increasing congestion as urbanization rises.

Natural Gas Development: Open Access and On-Shore Uses, Papua New Guinea

Castalia developed policies requiring firms exporting natural gas from Papua New Guinea to also supply on-shore customers, and to allow other firms to access their pipelines. While PNG’s natural gas export business was flourishing, local customers could not access gas, and smaller fields were not being developed due to lack of pipeline access.

New Business Model for the National Water Commission, Jamaica

Castalia identified and managed varied stakeholder interests to develop a business model that would enable the National Water Commission to reap efficiency gains, generate profits, and finance capital investments. The National Water Commission cannot meet growing demands for service without spending billions in capital expenditure. However, the utility cannot raise the finance needed due to the lack of efficiency and profitability.
