Independent Power Producers (IPPs)

Overview

Independent Power Producers (IPPs) or non-utility generator (NUG) are private entities (under unbundled market), which own and or operate facilities to generate electricity and then sell it to a utility, central government buyer and end users. IPPs may be privately-held facilities, cooperatives or non -energy industrial concerns capable of feeding excess energy into the system.

IPPs invest in generation technologies and recover their cost from the sale of the electricity. They can be great help to country's energy sector (especially when the public sectore do not have the required financial capacity for investment).

There are different goals for integrating IPPs into the nationals, but USAID has summarized the following three goals:

• "Attract outside capital to meet rapidly growing electricity needs without imposing large strains on the nations internal financial capabilities;
• Reduce electricity costs though competitive pressures; and,
• Assign risks in a more efficient or desirable manner."

Integrating IPPs into the Grid

The criteria for integrating IPPs into the electricity market depends on the specific country. However, there are generally four models used to describe the integration of IPPs into the grid. The picture below summarizes the four different models.

Risk for Independent Power Producers (IPPs)

Before investing in electricity generation, IPPs need to consider various factors like revenue security, market demand, and contract procurement. The following table from Best Practices Manual from USAID summarizes the risks of IPPs.

However, there are different mechanism to curb these risks namely,Power Purchase Agreement (PPA),sovereign guarantees or feed in tariffs.

Corruption during IPPs Contract Procurement

Normally, the involvement of private parties in contract procurement is expected to reduce corruption and increase transparency, but IPPs contract procurement can be corrupted due to the following reasons:

• IPPs contract are of a high value and thus attract embezzlement from public and private entities.
• IPPs contract are generally drafted under the crisis situation and are flexible. Thus, the involved parties can justify the deviation from least-cost method and can embezzle the funds.
• IPPs are fairly new to the electricity market and thus there is no clear guidelines on how to handle its contract procurement.
• IPPs procurement is usually handled between high ranking officials (as compared to other power sector procurement).This situation can provide extra level of protection for corrupt behavior.
