La Tejona is a 19.8 MW wind power project, situated in the middle of Costa Rica, near Lake Arenal, in the province of Guanacaste. The Tejona wind farm is made up of thirty VESTAS V47-660 kW wind turbines and is fully operational since the beginning of 2003.

Costa Rica and the Netherlands have endorsed and supported the project as an Activity Implemented Jointly (AIJ) in order to gain experience with the implementation of project based emission reduction. We invested

The baseline was determined by methodology ACM0002, version 06 of 19 May 2006 “Consolidated baseline methodology for grid-connected generation from renewable sources”. The baseline was validated by accredited designed operational entity TUV-SUD.

Additionality

Additionality is demonstrated by using the ‘Tool for the demonstration and assessment of additionality of 28 November 2005’. Both the Investment Analysis method and the Barrier Analysis Method were chosen and validated by TUV-SUD.

Why we purchased it?

We contributed in significant ways to the development of this project: we invested capital in the project and supplied technical know-how during the project development phase in cooperation with the Costa Rican electricity company. We also assisted the project through the CDM project cycle and purchased the generated CERs.
