Proposed decisions were issued in August. Comments and reply comments opposing the shut-off plan were filed on behalf of MGRA. The cost/benefit analysis initially proposed by M-bar Technologies and Consulting, LLC and other issues raised in our filings were cited as a key reasons for the Commission denial of the SDG&E shut-off plan.
