Jorge, <br><br>Based on my experience in Mexico, if you work for the electric company, that is the hardest part! Let me see if I can dig up a specific model of equipment that would be appropriate for the size you are requesting. <br>

<p class="MsoNormal"> </p><p class="MsoNormal" style="margin-bottom: 12pt;">Dear Jorge, <br><br>Almost any equipment that produces electricity can be connected to the grid with the proper equipment, however the grid managers are concerned that you have the right voltage, frequency, sine wave and that you have an automatic transfer switch so that you will not continue to put power into the grid when it goes down. For this, you can get grid interconnect synchroscope that "cleans-up" the power that comes out of your device, and that will automatically shut down if the grid goes (the scenario in which someone working on a line thinking that the grid is down and then gets shocked by the power you continue to put in is what utilities want to avoid). Try Lactronics, SMA, or Xantrex or anyone that makes inverters or rectifiers. Also, without this device, as long as the generator you are using is decent and producing the same voltage as is delivered to you, it is probably producing better power quality than the Costa Rican grid. In theory, you can just hook your generator into existing lines, and if you have an analouge power meter, and you are producing more power than you are using, you will make the meter spin back. Not suggesting this, just illustrating that connecting to the grid is really not too hard. <br>
<br>The other hurdle more challenging than the technical part is likely going to be getting the power company to sign on...<br><br>Best,<br><br>A </p><div><p class="MsoNormal">On Mon, May 9, 2011 at 7:32 PM, Charlie Ramos <<a href="mailto:cramos@biogreenengineering.com" target="_blank">cramos@biogreenengineering.com</a>> wrote:</p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);" lang="EN-US">Check out the Mopesa-60 KW.

We designed, built, and operated over 300 anaerobic digesters in Mexico and several of them used the Mopesa-60 KW. We also used the Caterpillar-85 KW that was imported from USA. I do not remember if either of my suggestions meets the IEEE 1547 (distributed energy) compliance, but you can probably find out very quick by making a phone call to both companies.</span><span lang="EN-US"></span></p>
