Table schema:
CREATE TABLE table_name_19 (_billion_ VARCHAR, electricity_production__kw_h INTEGER, _percentage_hydropower VARCHAR, _percentage_other_renewable VARCHAR, _percentage_coal VARCHAR)

Question: what is the highest electricity production (kw/h, billion) when the % other renewable is 0.4, % coal is 0 and % hydropower is more than 99?
SQL: SELECT MAX(electricity_production__kw_h), _billion_ FROM table_name_19 WHERE _percentage_other_renewable = 0.4 AND _percentage_coal = 0 AND _percentage_hydropower > 99
