Looking for Off Grid Battery Design Contractor

[Neal29]

Does anyone have any recommendations for an Off-Grid Battery Design firm?

[Sunking]

What state?

[Neal29]

What state?

Georgia. We are looking for a design firm to quote projects.

[Sunking]

Sorry how large of a project are we talking about? Unless this is a commercial or industrial sized project I seriously doubt any firm will even bother to respond. I own and operate a A/E design firm which does Solar Battery systems, I would not touch a single one-time customer smaller than say 50 Kwh/day. Anything smaller I just cannot make any money on. I site visit would blow all the profit. Now if you have multiple projects that is another story. Typical fees is T&E plus 15%

Wished I had a license for GA

Let me do some checking with my peers and see if I can come up with some names for you. I take it you are an Engineer or Project Manager in charge of the project with signature authority? You do understand there is no equipment made to do what you want and the system components will all be custom made to fit the application. One thing I do not see and might of missed it is a minimum daily power requirements. I see the interconnect requirements, but no Mwh/day requirement to be met. I also do not see any generator requirement. To be honest with you I do not know of any company that has ever attempted to design such a system and do not know if it is even remotely possible. Now that I think about it there is only two design firms I know of that can tackle this if it can be done at all; Bechtel or Babcock & Wilcox.

Over the Top

I know this is a ridiculous amount of information. We are a renewable energy company that specializes in medium size commercial and utility scale projects. Our sales team, has been receiving, RFP's for a fair amount of battery based systems. I would like to be able to have a reliable company to refer these customers to. Our website is U-renew.com. if you would like to research our company, and consider speaking? We may be able to become more clear on what we are looking for in a working relationship and it may create value for both parties involved.

Thank you,

I think a license in Chile would be more appropriate.
So Dereck how's your Spanish these days.

these sound a lot like shipping container type structures to house the batteries and related equipment.

[Sunking]

So Dereck how's your Spanish these days.

Not bad. Enough I can start a fight in any bar, or order off a menu in any restaurant.

Honestly though I can speak a little as that comes from living in TX, but I am also taking the Rosetta Stone course for Spanish right now in anticipation of moving to Panama or Costa Rica early next year. Panama is no problem as English is the countries language along with the USD.

Costa Rica is another story. In the main cities most speak English or some English but outside that mostly Spanish. But most of the young population there does speak English as it is a required subject matter in their school system. Lot of large US companies there and many more moving there in the near future.
