Energy Transfer (ET) and MPLX are standing out with attractive dividend yields—7.8% for ET and 8.5% for MPLX—while continuing to grow their payouts. Both are funding new expansion projects and acquisitions without overstretching their finances. ET retained $2 billion in cash in the first half of the year and is set for more growth with its latest projects. MPLX just hiked its payout by 12.5% for the second year straight, covers its dividend comfortably, and is also expanding through new deals and projects. The consistent payout increases look sustainable, though keep in mind the extra tax paperwork if you invest in MLPs.
