The wind turbine of claim 1, wherein the top ring further comprises a plurality of vertical openings, and the bottom ring further comprises a plurality of vertical openings separate from the troughs, the vertical openings in the top ring aligned with the vertical openings in the bottom ring. 5. A wind turbine, comprising: a nacelle;a tower comprising an upper section and a base section supported on a foundation; anda tower base ring assembly comprising a top ring, a bottom ring having an open center, and a middle ring having an open center, the top rim separate from and connected to the base section of the tower with connect bolts,the middle ring sandwiched between the top ring and the bottom ring, the top ring, the middle ring, and the bottom ring detachable from one another,wherein the middle ring comprises a plurality of apertures spaced circumferentially about the open center, the plurality of apertures extending radially from the open center towards an outer diameter of the middle ring, each aperture comprising an open radially inner end and a closed outer end that is offset from the outer diameter of the middle ring by a defined width around the periphery of the bottom ring, the apertures aligned with the connect bolts such that the connect bolts extend vertically into the apertures and are accessible from the open center of the middle ring via the open radially inner ends of the apertures. 6. The wind turbine of claim 5, wherein the top ring further comprises a plurality of vertical openings, and the bottom ring further comprises a plurality of vertical openings, the vertical openings in the top ring aligned with the vertical openings in the bottom ring. 7. The wind turbine of claim 5, wherein the base section of the tower comprises an L-flange connected to the top ring of the tower base ring assembly with the connect bolts. 8. A wind turbine, comprising: a nacelle;a tower comprising an upper section and a base section supported on a foundation; anda tower base ring assembly connectable to a foundation, the tower base ring assembly comprising a top ring and a second ring having an open center, the top ring separate from and connected to the base section of the tower with connect bolts,the top ring and the second ring detachable from one another,wherein the second ring comprises a plurality of radially extending passages spaced circumferentially about the open center and extending radially from the open center towards an outer diameter of the second ring, each passage comprising an open radially inner end and a closed outer end that is offset from the outer diameter of the second ring by a defined width around the periphery of the second ring, the passages aligned with the connect bolts such that the connect bolts extend vertically into the passages and are accessible from the open center of the middle ring via the open radially inner ends of the passages. 9. The wind turbine as in claim 8, wherein the second ring is a bottom ring of the base ring assembly. 10. The wind turbine as in claim 9, wherein the passages are troughs having a bottom surface and an open top. 11. The wind turbine as in claim 8, wherein the base section of the tower comprises an L-flange connected to the top ring of the tower base ring assembly with the connect bolts. 12. The wind turbine as in claim 8, further comprising a bottom ring, wherein the second ring is a middle ring coupled between the top ring and the bottom ring, and wherein the top ring, the middle ring, and the bottom ring are detachable from one another. 13. The wind turbine as in claim 12, wherein the passages in the second ring are apertures having an open top and open bottom.
