May refer to:

1) current

2) discount rate


overcurrent with inverse tripping characteristic

I-V Curve

The plot of the current versus voltage characteristics of a photovoltaic cell, module, or array. Three important points on the I-V curve are the open-circuit voltage, short-circuit current, and maximum power point.


May refer to: 1) initial investment cost, 2) extra terrestial irradiations


International Bank for Reconstruction and Development


International Climate Fund


direct-axis current

IDB (also IADB)

Inter-American Development Bank


International Energy Agency

IEC Standards

IEC standards are standards issued by the International Electric Committee (IEC) covering a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others.


induction generator


Insulated Gate Bipolar Transistor


International Climate Initiative

immersion heater

An electric heater that is immersed in water to heat it up


1) Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. 2) The combination of resistance and reactance affecting the flow of an alternating current, generally expressed in ohms.

impulse turbine

Also known as action turbine. This is a turbine that has the same pressure before and after the impeller. It operates in air at atmospheric pressure.

inception date

The initial starting date from which a contracted insurance policy provides risk coverage to the insured party.


Intended Nationally Determined Contribution


Compensation to a party for a loss or damage that has already occurred, or to guarantee through a contractual clause to repay another party for loss or damage that might occur in the future. The concept of indemnity is based on a contractual agreement made between two parties in which one party (the indemnitor, e.g. the insurer) agrees to pay for potential losses or damages caused by the other party (the indemnitee; e.g. the insured).

indemnity period

The maximum duration over which the insurers will be liable to indemnify the insured parties. Example: in the case of business interruption insurance, the indemnity period refers to the number of days over which the insurer has to pay loss of revenue compensation to the insured.
