MSEB is also planning to partly privatise its distribution network with an investment of Rs 2,000 crore over five years. ``MSEB will come out with a debenture issue in June to raise Rs 500 crore, which will be on the same lines as last year's debenture issue,'' Maharashtra deputy chief minister Gopinath Munde said. The SEB had issued debentures last year for Rs 500 crore, to finance its stake in Phase 1 of the Dabhol project.
