Castalia designs and develops public private partnerships to improve infrastructure service delivery.

David Ehrhardt—David has worked for more than ten years on effective design, implementation and management of public-private partnerships. This includes PPP transactions for railway and communications in Victoria (Australia); off-grid electrification in the Philippines; and wastewater infrastructure in the Czech Republic. He has worked on all stages of PPP transactions, from originating deals for investors including Azurix, the IFC and the EBRD, to helping the Government of Victoria (Australia) restructure troubled urban transport concessions. His advice on how to structure government PPP policies and process has been sought by countries as diverse as South Africa, Uganda and Indonesia. He was a lead contributor to the definitive guide to PPPs in the water sector. The World Bank also drew on David’s extensive experience and legal training in asking him to draft a standard Management Contract for water and electricity services, as well as standard provisions for key terms in Concession Contracts in these sectors.

For example, he advised the City of Lahore on a PPP for a new metro system, and was part of an IFC team that successfully procured private investment in off-grid power in the Philippines. He has also led projects to improve the management of contingent liabilities for PPP projects in Indonesia, the Philippines and Pakistan. Prior to Castalia, Alfonso was with the utilities practice at Deloitte & Touche’s, and worked as PPP advisor to the Government of Colombia.

Nils Janson—Nils advises governments and financial institutions on strategies for financing, developing, regulating, and managing infrastructure. He led a Castalia team advising the Government of Uganda on a national PPP strategy. He has advised governments in Brazil, El Salvador, Malawi, Mexico, Nicaragua, Paraguay, Saint Lucia, Sierra Leone, and Tanzania on PPP projects and policy frameworks.

Helen Martin—Helen has advised the Government of Uganda on developing a national PPP strategy and framework for developing and implementing PPPs, as well as on developing private sector participation in the water sector. She is managing a project in the Philippines to improve the Government’s management of contingent liabilities from PPP projects. Prior to joining Castalia, Helen has worked in both the public and private sectors—as an economist at the Ministry of Finance in Uganda and as a private sector strategy consultant in Europe.
