This mode seeks to maintain constant utility contribution to a site load. This is accomplished by monitoring utility contribution and trimming generator set load levels up and down as site loads change. Import control means the generator set is contributing less than the total site load requirements, and the utility supplies the difference. Export control means the generator set is contributing more than the total site load requirements, and the utility is absorbing the difference.
