Chongqing and Elderly Care Public Private Partnership Technical Assistance, PRC

Castalia proposed ways to address the mismatch in demand and supply of elderly care accommodations in Yichang City with the use of private sector participation. The PRC has become one of the world’s largest infrastructure markets, driven by strong economic growth and rapid urbanization. Demand for expanded and effective elderly care services has been increasing as 34 percent of the population is expected to be above the age of 60 by 2050. Further demand arises from government efforts to address regional disparities and ensure the availability of elderly care and services to its people, including the less privileged.

Corporate Financial Strategy for Indonesia’s State Electricity Company, Indonesia

Castalia developed a sustainable corporate financial plan for PLN, Indonesia’s national power utility, including a new revenue model, and recommended legislative changes. PLN needs to finance a US$180 billion expansion of the electricity system. It relies on subsidy to cover the gap between legislated tariffs and the cost of service. The size of the subsidy that would be required in the future led financial markets to question the fiscal sustainability of the arrangement.
